Abstract

The trusses have a wide application in Structural Engineering, being heavily used in the construction of bridges (highway and railway), in roof structures of buildings, towers of energy transmission, among many other uses. Usually they are relatively light weight and especially indicated to overcoming large spans or support high loadings. In this context, the trusses become an economical and practical solution. This paper aims to evaluate the structural behavior of planar trusses by means of Finite Element Method considering the physical nonlinearity. The material constitutive relation is described by a model based on the theory of Continuum Damage Mechanics. The nonlinear analysis is performed considering the Arc Length method with Newton - Raphson iterative process. From the numerical results, the proposed modeling presents a potential capability in the analysis of planar trusses due to its low complexity and low computational cost.
