Abstract

This paper presents a methodology to analyze the dynamic behavior of structures under moving loads. A finite element moving mesh algorithm has been developed in order to integrally move a part of the mesh following a moving load. This algorithm has been validated with the analytical [...]

Abstract

This paper presents a technological application of a general methodology to analyze cable structures under moving loads, particularly on the catenary-pantograph dynamic interaction. This work firstly describes the modeling of a finite element moving mesh which integrally moves [...]

Abstract

This chapter uses a mechanical method that involves non-linear analysis with deterministic and probabilistic approaches, as well as procedures of analysis based on limits states defined by displacements, in order to evaluate the behavior of a low rise RC building with plan irregularity [...]

Abstract

A constitutive model based on classical plasticity theory for non‐linear analysis of concrete structures using finite elements is presented. The model uses the typical parameters of non‐associated [...]

Abstract

In this paper a constitutive model based on an internal variable-formulation of plasticity theory for the non-linear analysis of concrete is presented. The model uses a new yield criterion [...]

Abstract

The paper introduces a new global damage evaluation method, thus obtaining a meaningful global damage index (GDI). A numerical procedure for predicting a local and global damage in civil engineering structures using the finite element method and a continuum damage model is presented. [...]

Abstract

The use of multi-scale procedures is encouraged by the continuous increase of computational capacity, but it is still a challenge performing a non-linear analysis of real composite structures without the aid of large computers. This work proposes a strategy to conduct non-linear [...]

Abstract

The Finite Element Method (FEM) has become the most popular numerical method for solving a [...]

Abstract

This paper presents a general two-scale procedure for the non-linear analysis of structures taking advantage of hybrid simulation concepts. This proposal considers the coupling and transition between elements [...]

Abstract

This works encompasses a broad review of the basic aspects of the Discrete Element Method for its application to general granular material handling problems with special emphasis on the topics of particle-structure interaction and the modelling of cohesive materials. On the one [...]
