13. On the Validation of a Numerical Model for the Analysis of Soil-Structure Interaction Problems
Abstract Modeling and simulation of mechanical response of structures, relies on the use of computational models. Therefore, verification and validation procedures are the primary means of assessing accuracy, confidence and credibility in modeling. This paper is concerned with the validation of a three dimensional numerical model based on the finite element

14. Soil-Framed Structure Interaction Analysis - A New Interface Element
AbstractInterfacial behavior between soil and shallow foundation has been found so influential to combined soil-footing performance and redistribution of forces in the superstructure. This study introduces a new thin-layer interface element formulated within the context of finite element method to idealize interfacial behavior of soil-framed structure intera

15. Relationships between structure of the tree component and environmental variables in a subtropical seasonal forest in the upper Uruguay River valley, Brazil
This study aimed to analyze relationships among the structure of the tree component, edaphic variables and canopy discontinuity along a toposequence in a seasonal upland (hillside) forest in southern Brazil. Soil and vegetation were sampled in 25 plots of 20 × 20 m each. We described the vegetation in terms of structure, richness and diversity, as well as b

17. Vibration of flexible and rigid plates on transversely isotropic layered media = : Vibração de placas flexíveis e rígidas em meios estratificados transversalmente isotrópicos / Vibração de placas flexíveis e rígidas em meios estratificados transversalmente isotrópicos
Este trabalho apresenta novos modelos para descrever o comportamento harmônico de placas rígidas e flexíveis incrustadas em meios estratificados. Incrustações profundas das placas são representadas por interfaces bi-materiais de meios viscoelásticos transversalmente isotrópicos. Incrustações rasas são representadas por meios estratificados viscoel

18. ANÁLISE DE TORRES DE LT CONSIDERANDO A INTERAÇÃO SOLO-ESTRUTURA / THE SOIL-STRUCTURE INTERACTION IN TRANSMISSION LINES LATTICED STEEL TOWERS ANALYSES
O modelo mecânico usualmente adotado no projeto de torres metálicas treliçadas é bastante simples, utilizando elementos de treliça e/ou pórtico espacial, e resolvido através de uma análise estática e linear ou não linear geométrica. Nas hipóteses de carga de ruptura de um cabo condutor ou um cabo pára-raios o carregamento é considerado através

19. Avaliação do comportamento solo-estrutura de elementos de fundação tipo sapata estaqueada / Assessment of the behavior of soil-structure foundation elements like piled footing
This work aims to study the behavior and interaction between soil, shallow footing and pile, based on the implementation and monitoring of four direct load tests performed on: a single shallow footing, a shallow footing with one pile, a shallow footing with four piles and a pile alone. During the load tests, vertical displacements were monitored at different

21. Análise da interação solo-estrutura aplicada a riser rígido em catenária através da formulação co-rotacional / Analysis of the soil-structure interaction applied to steel catenary riser using corotational formulation
A explotação de petróleo em ambientes off-shore possui inúmeras dificuldades, dentre as quais lâminas d águas cada vez mais profundas. Neste contexto, as linhas submarinas são componentes de grande importância nesta atividade, pois estabelecem a comunicação entre as unidades de produção e os equipamentos submarinos. Este trabalho estuda a intera�

22. RESOURCE SHARING AND DISTRIBUTION OF RISK IN ANNUAL SPECIES OF TROPICAL ZONE Semiarid / Partilha de recurso e distribuiÃÃo de riscos em espÃcies anuais da zona tropical semiÃrida
Theoretical and empirical inferences about resources sharing and risk spreading based on seed germination and plants phenodynamics are concentrated in studies of annual desert species. These mechanisms should be standard for species that coexist in any environment where the risk of reproductive failure is high, as in Brazilian tropical semiarid. This study

23. A probabilistic capacity spectrum strategy for the reliability analysis of bridge pile shafts considering soil structure interaction
This paper presents a probabilistic capacity spectrum strategy for the reliability analysis of a bridge pile shaft, accounting for uncertainties in design factors in the analysis and the soil-structure interaction (SSI). Monte Carlo simulation method (MCS) is adopted to determine the probabilities of failure by comparing the responses with defined limit stat

24. Non linear geometric analysis of soil-structure interaction via BEM/FEM coupling / Análise não linear geométrica do acoplamento solo-estrutura através da combinação MEC-MEF
This work presents an alternative coupling of the boundary element method (BEM) and the finite element method (FEM) to create a computer program for non linear geometric analysis of frames coupled to continuous domains, applied to soil-structure interaction. A linear elastic behavior is considered for the soil, modeled by BEM. An alternative formulation is a
