Robustness of steel framed buildings with pre-cast concrete floor slabs

Miratashi Yazdi, Seyed Mansoor January 2014 (has links)
Following some incidents in high-rise buildings, such as Ronan Point London 1968, in which collapse of a limited number of structural elements progressed to a failure disproportionate to the initial cause, consideration of robustness was introduced in British Standard. The main method of preventing progressive collapse for providing robustness to steel framed buildings with precast concrete floor slabs focuses on the allowable tying forces that the reinforcement in between the slabs and in hollowcores should carry. However there are uncertainties about the basis of the practical rules associated with this method. This thesis presents the results of numerical and analytical studies of tie connection behaviour between precast concrete floor slabs (PCFS). It is shown that under current design regulations the tie connection is not able to resist the accidental load limit applied on the damaged floor slabs. By establishing the capability of a finite element model to depict and predict the behaviour of concrete members in situations such as arching and catenary action against several experimental tests, an extensive set of parametric studies was conducted in order to identify the effective parameters in enhancing the resistance of the tie connection between PCFSs. These parameters include: tie bar diameter, position, length, yield stress and ultimate strain; the slab’s height, length; and the compressive strength of the grouting concrete in between the slabs that encases the tie bar. Recommendations are made based on the findings of this parametric study in order to increase the resistance of the tie connection. Based on the identified effective parameters in the parametric study a predictive analytical relationship is derived which is capable of determining the maximum vertical displacement and load that the tie connection is able to undergo. This relationship can be used to enable the connection to capture the accidental limit load on a damaged slab. The identified parameters are examined in a three dimensional finite element model to assess their effect when columns of the structure are lost in different locations such as an edge, corner or internal column. Based on the findings of this study methods for improving the connections performance are presented. Also the effect of alternative transverse tying method is evaluated and it is concluded that although this kind of tie increases the load carrying capacity of the connection, its effect on the catenary action is not significant.

Métodos: Estudo de coorte prospectivo, realizado no Hospital Universitário da Faculdade de Medicina de Jundiaí (HU-FMJ). Foram selecionadas 133 primíparas, no puerpério imediato, com idade entre 18-35 anos, que tiveram parto vaginal com episiotomia espontâneo ou instrumental por fórcipe. A contração dos músculos do assoalho pélvico (MAP) foi avaliada 40-55 dias após o parto, por meio de eletromiografia de superfície - EMGs (avaliando-se tônus de base ¿ TB, contração voluntária máxima - CVM e contração sustentada média - CSM) e por graduação de força segundo Escala de Oxford Modificada (graus 0-5). Avaliou-se a presença de IU durante a gestação e puerpério, utilizando o Internacional Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). Os métodos estatísticos utilizados foram teste de Qui-Quadrado (X2) ou exato de Fisher para comparar proporções e teste Mann Whitney para comparar médias. Resultados: A média de idade foi de 22,3 anos (±4,2), o IMC gestacional foi de 27,6 Kg/m2 (±5,1). Apenas 44 mulheres realizaram avaliação puerperal, sendo uma descontinuada, 72,1% submetidas ao parto vaginal (PV) e 27,9% ao parto fórcipe (PF). A ocorrência de laceração perineal foi mais frequente no grupo PF (33,3%) do que no grupo PV (3,2%), mas as complicações devidas à episiotomia foram relatadas em apenas 7,0% dos casos, todos no grupo PV. A prevalência de IU foi de 37,6% durante a gestação e 39,5% no puerpério, sendo 32,3% do grupo PV e 58,3% do grupo PF. Houve mais IU desencadeada no puerpério no grupo PF [RR=3,10 (IC=95% 1,16-8,28); p=0,0468]. O sintoma urinário predominantemente referido no puerpério em ambos os grupos foi a urgeincontinência (29,5%), e a média do escore ICIQ foi 2,3 (±3,8) para o grupo PV e 4,2 (±3,9) para o grupo PF, não havendo diferença significativa entre os grupos. Apresentaram grau reduzido de força muscular 66,7% das puérperas do grupo PF e 27,6% do grupo PV. Os valores médios encontrados para TB, CVM e CSM do grupo PV foram 4,6?V, 23,2?V e 16,8?V e do grupo PF 3,4?V, 14,2?V e 10,7?V, respectivamente, havendo diferença significativa para TB e CVM. Conclusão: Entre as mulheres do estudo em questão observou-se associação do parto fórcipe com a diminuição da função dos MAP 40-55 dias após o parto na graduação de força por palpação e parâmetros eletromiográficos de TB e CVM, sem associação com IU / Abstract: Objective: To evaluate the influence of the spontaneous or instrumental vaginal delivery by forceps in the muscular contraction of the pelvic floor of primiparas and urinary incontinence (UI). Methods: Prospective cohort study, carried out in the University Hospital of the Faculty of Medicine of Jundiaí (HU-FMJ). 133 primiparas in the immediate puerperium, aged between 18-35, that have had vaginal delivery with spontaneous or instrumental episiotomy by forceps were selected. The contraction of the pelvic floor muscles (PFM) was evaluated 40-55 days after delivery, by means of surface electromyography - EMGs (evaluating tonus of basis - TB, maximum voluntary contraction - MVC and average of sustained contraction - ASC) and by muscle strenght graduation according to the Modified Scale of Oxford (degrees 0-5). The presence of UI during pregnancy and puerperium was evaluated according to the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). The statistical methods used were the Qui-Square test (X2) or the accurate Fisher indicator to compare ratio and the Mann Whitney test to compare averages. Results: The average age was 22,3 years old (±4,2), gestacional BMI was 27,6 Kg/m2 (±5,1). Only 44 women returned for the puerperal evaluation and one volunteer was discontinued, 72.1% gave birth via spontaneous vaginal delivery (VD) and 27.9% via instrumental vaginal delivery (FD). The occurrence of perineal laceration was more frequent in the FD group (33.3%) than in the VD group (3.2%), but complications due to episiotomy were reported in only 7.0% of the cases, all in the VD group. There were more UI triggered puerperium in the group PF [RR=3,10 (CI=95% 1,16-8,28); p=0,0468]. The prevalence of UI was of 37,6% during pregnancy and 39.5% in the puerperium, where 32,3% of the VD group and 58,3% in the FD group. The urinary symptom predominantly related in the puerperium in both groups was the urge incontinence (29.5%), and the average of the ICIQ score was 2,3 (±3,8) for the VD group and 4,2 (±3,9) for the FD group, without significant differences between the groups. Showed reduced degree of muscular strength 66,7% of the puerperal in the FD group and 27.6% of the VD group. The found average values for TB, MVC and SVC in the VD group was 4,6 ?V, 23,2?V and 16,8?V and in the FD group was 3,4 ?V, 14,2?V and 10,7?V, respectively, with significant difference for TB and MVC. Conclusion: Among the women of the study concerned noted an association of forceps delivery and the reduction of the function of MAP was observed 40-55 days after delivery in the graduation of muscle strenght for palpation and electromyographic parameters of TB and MVC, not associated with UI / Mestrado / Saúde Materna e Perinatal / Mestra em Ciências da Saúde

Ampliar o conhecimento sobre esta estrutura poderia prevenir ou mesmo tratar tais disfunções. Objetivo: (1) Avaliar e comparar a contratilidade dos músculos do assoalho pélvico (MAP) em diferentes fases do ciclo vital feminino: nuligestas; primigestas; puérperas primíparas; climatéricas e pós-menopausadas. (2) Correlacionar a contratilidade dos MAP e sua coativação a partir da contração dos músculos transverso abdome/oblique interno (TrA/OI) com os fatores: idade; prática de atividade física; gestação; Índice de Massa Corpórea (IMC); paridade; presença e severidade dos sintomas urinários. Métodos: 331 mulheres participaram do estudo e foram avaliadas através dos questionários: International Consultation on Incontinence Questionnaire - Short Form (ICIQ UI-SF) e International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) para estudo dos sintomas urinários e eletromiografia (EMG) dos MAP para avaliação da contratilidade. Destas mulheres 92 foram submetidas também à EMG dos músculos TrA/OI e analisadas de acordo com os fatores propostos para estudar a influenciar da contratilidade na coativação. Resultado: Entre os grupos estudados, as nuligestas apresentam maior contratilidade (46.59±16.83?V) dos MAP, seguido do grupo das primigestas (35.31±18.22?V), puérperas de parto cesariana (33.28±13.00?V), puérperas de parto vaginal (31.23±16.12?V), climatéricas (25.81±17.57?V) e pós menopausadas (21.23±15.11?V). Houve correlação negativa entre a contratilidade dos MAP e a idade (p<0.0001), paridade (p<0.0001), ICIQ-SF (p=0.0001) e ICIQ OAB (p=0.0006). Não foi verificada correlação entre MAP e IMC (p=0.1348) e as mulheres que praticam atividade físca apresentam maior contratilidade dos MAP (p=0.03). Sobre os fatores que podem interferir na coativação foram significativos: a gestação (p=0.01), prática de atividade física (p=0.03) e altos valores do escore do ICIQ IU SF (p<0.0001). Em análise multivariada a atividade física juntamente com ICIQ IU SF influenciaram a contratilidade dos MAP e TrA/OI (p<0.001). Conclusão: A contratilidade dos MAP durante o ciclo vital feminino apresenta-se na seguinte ordem decrescente: nuligestas, primigestas, primíparas pós parto cesariana, primíparas pós parto vaginal, climatéricas e pós menopausadas. Os MAP apresentam sua contratilidade correlacionada inversamente com a idade, paridade, e escores do ICIQ SF e ICIQ OAB. A coativação entre o TrA/OI e os MAP é influenciada diretamente pela atividade física, e inversamente pela gestação e ICIQ IU SF. Em análise multivariada, verificou-se que, conjuntamente, a coativação é influenciada diretamente pela prática de atividade física e inversamente pelo escore ICIQ IU SF / Abstract: The female pelvic floor (PF) is a complex and vulnerable structure, susceptible to a number of functional changes throughout life. Increasing the knowledge of this structure could prevent or even treat such disorders. Objective: (1) To evaluate and compare the contractility of the pelvic floor muscle (PFM) at different stages of the female life cycle: nulliparous; primigravidae; primiparous postpartum women; climacteric and menopause. (2) To correlate the contractility of the PFM and their coactivation from the contraction of the transversus abdomen muscles/ internal oblique (TrA/IO) with the following factors: age; physical activity; pregnancy; Body Mass Index (BMI); parity; presence and severity of urinary symptoms. Methods: 331 women were evaluated through questionnaires: International Consultation on Incontinence Questionnaire - Short Form (ICIQ-UI SF) and International Consultation on Incontinence Questionnaire Overactive Bladder (OAB-ICIQ) for study of urinary symptoms and PFM electromyography (EMG) for contractility assessment. Of these women 92 were also submitted to the TrA EMG / IO muscles and analyzed according to the proposed factors to study the influence of contractility in coactivation. Results: Among the groups, the nulliparous have greater contractility (46.59 ± 16.83_V) of PFM, followed by the group of first pregnancy (35.31 ± 18.22_V), cesarean birth mothers (33.28 ± 13.00_V), vaginal birth mothers (31.23 ± 16.12_V), weather (25.81 ± 17.57_V) and postmenopausal (± 15.11_V 21:23). There was a negative correlation between the contractility of PFM and age (p <0.0001), parity (p <0.0001), ICIQ-SF (p = 0.0001) and ICIQ OAB (p = 0.0006). There was no correlation between the contractility of PFM and BMI (p = 0.1348). Women who practice physical activity have greater contractility of PFM About the factors that can interfere with coactivation were significant: pregnancy (p = 0.01), physical activity (p = 0.03) and high values of the ICIQ UI SF score (p<0.0001). In multivariate analysis, physical activity along with ICIQ UI SF influence the contractility of PFM and TrA/IO (p<0.001). Conclusion: The contractility of PFM during the female life cycle is presented in the following descending order: nulliparous, primiparous, primiparous after cesarean delivery, primiparous after vaginal delivery, climateric and postmenopausal. The PFM present their contractility inversely correlated with age, parity, and scores of ICIQ SF and ICIQ OAB. The co-activation between the TrA /IO and PFM is directly influenced by physical activity, and inversely by pregnancy and ICIQ UI SF. In multivariate analysis, it was found that, together, the co-activation is directly influenced by physical activity and inversely by ICIQ UI SF score / Doutorado / Fisiopatologia Cirúrgica / Doutora em Ciências

PREVALENCE OF SPORTS-RELATED STRESS URINARY INCONTINENCE IN THE FEMALE COLLEGIATE ATHLETE

Pagorek, Stacey 01 January 2019 (has links)
Urinary incontinence is a health condition that is associated with involuntary leakage of urine. Stress urinary incontinence (SUI) describes involuntary leakage of urine on effort or exertion and can impact one’s ability to participate in activities and affect quality of life. Furthermore, clinical management of this health condition is challenging as individuals who experience urinary incontinence often do not report this concern to a health care provider. Stress urinary incontinence is not typically a health concern associated with young, healthy athletes. However, researchers have begun to examine the presence of this health condition amongst both a younger population and in athletes. Therefore, the purpose of this study is to assess the prevalence of stress urinary incontinence in collegiate female athletes. This study involved the development of an electronic survey tool to assess the prevalence of SUI in the female collegiate athlete. Female collegiate athletes from six different NCAA Division I schools were asked to complete the survey. The overall response rate for the survey was 32.6% (333/1020). Results indicate that SUI does in fact occur in NCAA Division I collegiate female athletes. Overall, 68.5% of female collegiate athletes surveyed reported ever experiencing SUI. During daily life activities (cough, sneeze, laugh), 54.2% of female collegiate athletes reported experiencing SUI. During participation in their sport, 40.0% of female collegiate athletes reported experiencing SUI, referred to as sports-related SUI. When reporting SUI experienced during either sport participation or during other exercise-based activities, 58.2% of female collegiate athletes reported SUI. The proportion of female athletes reporting sports-related SUI varied by sport. The highest prevalence of leakage in sport was reported by gymnasts (80%) and the lowest prevalence was reported by those who participated in rifle (0%). Over half (52.3%) of female athletes who reported sports-related SUI said their symptoms first began in high school. While majority of female collegiate athletes stated they did not avoid their sport because of SUI, one-fifth (20.5%) of athletes with sports-related SUI reported they alter how they move in their sport out of concern for leakage. The impact of sports-related SUI on other aspects of life (family, social, or school life) were reported to be minimal. Athletes who experience sports-related SUI are most likely to tell either a teammate (49%) or no one (36%). Very few female athletes have told someone in healthcare about this concern: doctor (3%), athletic trainer (4%); physical therapist (1%). Furthermore, only 3% of female collegiate athlete with sports-related SUI reported ever seeking treatment and only 25.8% reported they would find value in seeing a healthcare provider to discuss SUI. Most (76.7%) female collegiate athletes, whether they reported SUI or not, stated they had never been instructed on exercises to strengthen the pelvic floor muscles and 60.6% reported they would find educational programs involving exercises to decrease or prevent SUI beneficial. In conclusion, SUI does occur in the female collegiate athlete and is often not reported to healthcare providers. Based on this information, the general practice of screening athletes for relevant health conditions during pre-participation physicals may need to include additional questions for SUI. Further investigation needs to explore how to best engage and educate female collegiate athletes on the subject of SUI and how to successfully communicate with and address those with the condition.
