1. Dynamic Response Analysis of Geogrid Reinforced Embankment Supported by CFG Pile Structure During a High-Speed Train Operation
Abstract The performance of railroad structure has a tremendous influence on the safety and stable operation of high-speed trains. Strong vibrations and the degradation rate of the track are the main factors affecting the transport safety of a railroad built over a weak soil. Geogrid reinforced embankment supported by pile structure is a new efficient constr

2. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

3. 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

4. Numerical combination for nonlinear analysis of structures coupled to layered soils
This paper presents an alternative coupling strategy between the Boundary Element Method (BEM) and the Finite Element Method (FEM) in order to create a computational code for the analysis of geometrical nonlinear 2D frames coupled to layered soils. The soil is modeled via BEM, considering multiple inclusions and internal load lines, through an alternative fo

5. Comportamento de estacas escavadas de pequeno diâmetro em solo laterítico e colapsível da região de Campinas/SP / Behavior of bored piles of small diameter in collapsible and lateritic soil in the region of Campinas/SP
This paper aims to study the behavior of bored piles of small diameters, subjected to axial compression loads by static load tests carried out at the Field of Experimental Soil Mechanics and Foundation 2 at Unicamp. The CEMSF2 has a geological profile whose first layer is composed of silty clay, with coluvionar, lateritic, and collapsible features.This study

6. DeterminaÃÃo do coeficiente de transferÃncia de cargas nas fundaÃÃes de silos verticais cilÃndricos de base semi-V
Engineering structures are designed according to the imposed stress. In the case of silos, there is not a Brazilian standard regulation to prescribe their projects and actions. This limitation leads designers to use the foreign standards requirements which, however, differ from one another. This paper shows the evolution of knowledge about the subject, and a

7. 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

8. Behavior of concrete "mega" piles, installed in collapsible soil / Comportamento de estacas Mega de concreto, implantadas em solo colapsivel
There are very common cases of works that have problems due to the collapse of foundations and soil, and in the most of the works, the solution applied is the underpinning with Mega piles of concrete that, despite the wide use, there are few studies on this type of foundation. With the aim of add parameters to the technical means about this type of foundatio

9. Análise do comportamento de estacas strauss submetidas a carregamento horizontal no solo da região de Londrina - PR
In Londrina city, Strauss piles are frequently used as retaining structure for building basement excavation, being submitted to horizontal load. However, the projects of such retaining structures are usually conducted using design methods that do not take the concrete cracking of pile transversal section and the properties of lateritic tropical soil into acc
