Retroanálise de uma escavação de vala escorada a céu aberto de uma linha do metrô de São Paulo / Back analyses of on open trench excavation for the São Paulo subwayGiulio Peterlevitz Frigerio 23 March 2004 (has links)
Esta dissertação apresenta em primeira etapa o trabalho desenvolvido para averiguar a adequação dos modelos reológicos de Mohr-Coulomb e de Endurecimento de solo, para representar as deformações e distorções que ocorrem no sistema soloestrutura, quando do processo de escavação de valas escoradas. Além disto, em uma segunda etapa fazem-se estimativas de previsão de danos causados em edificações, em decorrência das escavações de uma vala escorada da linha 1 do Metropolitano de São Paulo (Metrô S.P.). A primeira e a segunda etapa foram feitas através de 810 simulações numéricas, em elementos finitos utilizando-se o software PLAXIS, associadas a retroanálise por processo direto do módulo de deformabilidade a 50% da tensão de ruptura dos solos utilizando-se para isto o processo direto. Apresenta-se também uma síntese da formação e dos tipos de solos que constituem a bacia sedimentar de São Paulo, onde se localiza a seção experimental nº1 objeto de estudo desta dissertação. Faz-se uma breve revisão bibliográfica a respeito das técnicas de retroanálise. Apresentam-se critérios para escolha de intervalos de parâmetros geotécnicos que representem o sistema solo-estrutura no processo de escavação. Foram feitas análises paramétricas para determinar os parâmetros geotécnicos que mais influenciam o sistema solo-estrutura. Comparam-se os modelos constitutivos de Mohr-Coulomb e de endurecimento na previsão das deformações. Por fim, faz-se a previsão do nível de danos causados pelas escavações da vala, a um edifício hipotético / This dissertation presents, in a first part, the work done to verify how appropriate are the Mohr-Coulomb and hardening soil constitutive models to represent the strains and the distortions associated with escavations of braced wall process. In the second part, estimates are made of the damages in constructions due to the braced excavations of line one of Sao Paulo Subway (Metrô S.P.). In the two phases, 810 numeric simulations were made, in finite elements using the software PLAXIS, associated the back analysis for direct process. It is presented a synthesis of the formation and the types of soils that constitute the basin of the sediments of the city of São Paulo, where is located the section experimental nº1, object of study of this dissertation. It is presented an short bibliographical revision regarding the back analysis techniques. Criteria for choice of intervals of parameters geotechnical that represent the system soil-structure in the excavation process are presented. Parametric analyses are made to determine which the parameters have larger influence in the behavior of the system soil-structure. The behavior of the soil-structure system is simulated using the Mohr-Coulomb and hardening soil constitutive models. The Mohr-Coulomb and hardening soil constitutive models are compared in the forecast of the deformations. Finally, it is made the forecast of the level of damages to a hypothetical building caused by the braced excavations

Nosná ocelová konstrukce zastřešení tribuny sportovního stadionu / Load carrying steel structure of the sport stadium roofingHubáček, Ondřej January 2018 (has links)
This diploma thesis deals with design load bearing steel structure of the sport stadium roofing with 67,2 m length and 28,8 m width. Roofing structure is designed and examined in two versions. Variant A is designed like tubular truss girder with axis distance 4,8 m. Variant B is designed like welded solid-web girder with same axis distance. These versions are compared by weight, manufacturing complexity and appearance, preferable version is processed in detail. Drawings contain layout of both versions and manufacturing drawings of truss.

Patrová budova / Multi-storey buildingSurovec, Daniel January 2018 (has links)
The object of this thesis is to design and assess steel structure of multi-storey office center in Vsetín. Floor plan dimensions of building are 48x40m. The building has ten floors. Overall height is 35,5m. The building ceilings made of composite steel and concrete structure. The part of build are roofer atrium and one bigger room aula with dimensions 24x16m. Two construction variants were designed and assessed. Longitudinal and transverse rigity of variant A is ensured by truss bracing. Transverse rigity of variant B is ensured by truss bracing and longitudinal rigity is braced by bracing frames. The variant A is better.

Obchodní a nákupní centrum v Brně / Trade House in BrnoSerbousková, Kateřina January 2018 (has links)
The final thesis deals with the design of the steel loadbearing structure of the shopping center situated in Brno. The built-up floor area is 1973 m2 (L-shaped ground plan with dimensions 48 m x 50 m). The construction consists of three parts. Building A has four above-ground floors and reaches a height of 25.5 m. The steel structure of mono-pitched roof is designed in two options. Both options consist of full-length purlins and truss girders. Building B is a single-storey building with a mono-pitched roof top reaching 8.1 m high. Building C is three-storey with a flat roof. The first floor has a construction height of 4.5 m and the remaining two floors reach height of 3.6 m, which coincide with building A. The steel structure is made of steel-concrete composite ceilings and pin-supported columns. In the case of bracings, pressure was eliminated by means of non-linearities.The work includes proposal, assessment of the supporting structure and calculation of the directional details. Internal forces were determined based on a static analysis in the SCIA Engineer calculation program.
