Atualmente, o crescimento dos problemas de vibrações excessivas sobre pisos mistos (aço-concreto) tem conduzido à necessidade de desenvolvimento de critérios específicos para projetos estruturais submetidos à ação de atividades humanas rítmicas. Com base no desenvolvimento desta dissertação de mestrado, objetiva-se, principalmente, verificar a influência das ligações estruturais (ligações viga-viga), sobre a resposta dinâmica não-linear de pisos mistos (aço-concreto) de edificações, quando submetidos a cargas dinâmicas humanas rítmicas. Deste modo, o carregamento dinâmico empregado para a simulação das atividades humanas sobre o modelo estrutural investigado foi obtido através de testes experimentais com indivíduos praticando atividades rítmicas e não rítmicas. O modelo analisado nesta dissertação corresponde a um piso misto (aço-concreto) com uma área total de 1600m2 e consiste de um ambiente onde serão desenvolvidas atividades de ginástica aeróbica. O sistema estrutural é constituído por lajes de concreto armado apoiadas sobre vigas de aço, simulando o comportamento de um sistema estrutural misto (aço-concreto) com interação total. A metodologia de análise desenvolvida emprega técnicas usuais de discretização presentes no método dos elementos finitos, com base no emprego do programa ANSYS. A modelagem do sistema contempla ligações estruturais do tipo rígidas, semirrígidas e flexíveis. Os valores das acelerações de pico foram comparados com os limites recomendados por normas de projeto, baseando-se em critérios de conforto humano. As conclusões alcançadas ao longo deste trabalho de pesquisa revelam que as ligações estruturais do tipo viga-viga não apresentam influência significativa, no que diz respeito a resposta dinâmica não-linear da estrutura. Por outro lado, as acelerações de pico obtidas com base na análise dinâmica não-linear apresentam valores elevados indicando que o piso misto (aço-concreto) investigado apresenta problemas de vibração excessiva inerentes ao conforto humano. / Nowadays, the increasing incidence of composite (steel-concrete) floors vibration problems due to human rhythmic activities led to a specific design criteria to be addressed in structural design. The main objective of this investigation is to evaluate the influence of the structural connections (beam-to-beam connections) on the composite floors nonlinear dynamic response, when submitted to human rhythmic dynamic loads. The dynamic loads were obtained through experimental tests with individuals carrying out rhythmic and non-rhythmic activities. The investigated structural model was based on building composite floors and consisted of a typical office building interior bay with a total are of 1600m2 used for aerobics. The structural system are composed of a composite (steel-concrete) solution made of an I steel profile and a reinforced concrete slab. In this investigation a complete interaction between the concrete slab and steel beams was considered. The proposed analysis methodology adopted the usual mesh refinement techniques present in the finite element method simulations implemented in the ANSYS program. The structural system finite element modelling have considered rigid, semi-rigid and pinned beam-to-beam joints. The peak accelerations were compared with limits proposed by design codes and recommendations, based on human comfort criteria. The results obtained in this investigation indicated that the structural connections (beam-to-beam connections) can have a relevant influence on the composite floor nonlinear dynamic response. On the other hand, the peak accelerations obtained in this investigation, based on a nonlinear dynamic analysis, indicated that the investigated composite floor violated the human comfort criteria, as well as its vibration serviceability limit states.

[ES] El diseño de puentes, a diferencia de lo que ocurre con el diseño de edificios o con el diseño de túneles ha dejado de lado la consideración de la acción del fuego hasta la fecha. Este vacío normativo, combinado con la gran repercusión económica y social de colapsos de puentes en el pasado como consecuencia de incendios, ha motivado un rápido incremento del número de estudios relativos a la ingeniería frente al fuego en el ámbito de los puentes. Aunque la acción del fuego no resulta del todo desconocida en el ámbito de las estructuras, sí que existen una serie de singularidades que impiden la trasposición directa de recomendaciones o de modelos de fuego simplificados ya desarrollados en otros campos que ya incorporan la acción del fuego en el diseño. En este contexto, el trabajo que a continuación se expone parte de un incendio ocurrido en el estado de Alabama en 2002, cuyas consecuencias fueron la demolición de un puente mixto de 37 metros de vano central, para plantear y validar una metodología que aborda el problema de forma numérica mediante tres modelos acoplados secuencialmente: modelo de incendios, modelo térmico y modelo mecánico Realizada una validación a nivel general se descubre que, aunque la configuración geométrica final obtenida se ajustan bastante a la realidad, la definición del incendio ha supuesto un gran número de hipótesis. Es por ello que se decide, en una segunda parte, realizar una campaña experimental que permita registrar la potencia del fuego, las temperaturas del gas y del acero y las flechas en un puente construido ad-hoc en el campus de la Universitat Politècnica de València. Este puente experimental tenía un vano único de 6 m de luz y fue sometido a cargas de fuego de hasta 1.3 MW. Mediante el empleo de los registros realizados en la campaña experimental se ha validado el modelo de incendio, el modelo térmico y el modelo mecánico. Con todo ello se ha puesto en evidencia la importancia del viento en la acción del fuego, la magnitud de los gradientes térmicos espaciales y la urgencia de desarrollar procedimientos simplificados que permitan la incorporación del fuego como acción en el ámbito de los puentes Las validaciones específicas de cada modelo han permitido además llegar a una serie de conclusiones de gran interés para la realización de futuras campañas experimentales en puentes a mayor escala. / [CAT] El disseny de ponts, a diferència del que passa amb el disseny d'edificis o amb el disseny de túnels ha deixat de banda la consideració de l'acció del foc. Aquest buit normatiu, combinat amb la gran repercussió econòmica i social de col·lapses de ponts com a conseqüència d'incendis, ha motivat un ràpid increment del nombre d'estudis relatius a l'enginyeria del foc del foc en l'àmbit dels ponts. Encara que l'acció del foc no resulta del tot desconeguda en l'àmbit de les estructures, sí que hi ha una sèrie de singularitats que impedeixen la transposició directa de recomanacions o de models de foc simplificats ja desenvolupats en altres camps que ja incorporen l'acció del foc al disseny. En aquest context, el treball que a continuació s'exposa part d'un incendi ocorregut a l'estat d'Alabama en 2002 i que va provocar la demolició d'un pont mixt de 37 metres de va, per plantejar i validar una metodologia que aborda el problema de forma numèrica mitjançant tres models acoplats seqüencialment: model d'incendis, model tèrmic i model mecànic Realitzada una validació a nivell general es descobreix que, encara que la configuració geomètrica final obtinguda s'ajusta en gran mesura a la realitat, la definició de l'incendi ha suposat un gran nombre d'hipòtesis. És per això que es decideix, en una segona part, realitzar una campanya experimental que permeta registrar la potència del foc, les temperatures del gas i de l'acer i les fletxes en un pont construït ad hoc al campus de la Universitat Politècnica de València. Aquest pont experimental presenta un va únic de 6 m de llum i va ser sotmès a càrregues de foc de fins a 1.3 MW. Mitjançant l'ús dels registres realitzats a la campanya experimental s'ha validat el model d'incendi, el model tèrmic i el model mecànic. Amb tot això s'ha posat en evidència la importància del vent en l'acció del foc, la magnitud dels gradients tèrmics espacials i la urgència de desenvolupar procediments simplificats que permetin la incorporació del foc com a acció en l'àmbit dels ponts Les validacions específiques de cada model han permès a més arribar a una sèrie de conclusions de gran interès per a la realització de futures campanyes experimentals en ponts a major escala. / [EN] To date, the fire action has been left aside in the bridge design despite this action has been widely considered in other structures such as building and tunnels. This regulatory vacuum, combined with the great economic and social impact of bridge collapses in recent times as a result of fires, has led to a rapid increase in the number of studies related to fire engineering in the field of bridges. Although the action of fire is not entirely unknown in the field of structures, there are a number of singularities that prevent the direct transposition of recommendations or simplified fire models from such fields. In this context, the study started by using a real fire which occurred in the state of Alabama in 2002 and led to the demolition of the 37-meter main span of a composite concrete and steel bridge to introduce and validate a methodology that numerically addresses the problem by uncoupling the problem in three different models: fire model, thermal model and mechanical model. Once the validation was accomplished at a general level, it was discovered that, although the geometrical data were quite adjusted to reality, the definition of the fire had involved a large number of hypotheses. That is why carrying out an experimental campaign to record the power of the fire, the gas and steel temperatures and the vertical deflections of a bridge built ad-hoc on the campus of the Universitat Politècnica de València became a priority. This 6-meter single span experimental bridge was subjected to fire loads of up to 1.3 MW. Through the use of the information recorded during the experimental campaign, the fire model, the thermal model and the mechanical model were validated. Moreover, the importance of wind in the action of fire, the magnitude of spatial thermal gradients and the urgency of developing simplified procedures which allow the consideration of fire as an action in the field of bridges were also highlighted. Last but not least, the validation of the different models allowed the author to include useful guidelines in order to define future experimental campaigns with more powerful fires and longer span bridges. / Alós Moya, J.
