Zapata-Medina Ingeniería Girders bending patch loading structural stability longitudinal stiffeners This paper is aimed at studying the elastoplastic behavior of l ongitudinally stiffened girder webs subjected to patch loading and bending. The investigation is carried out by means of nonlinear finite e lement analysis to study the structural behavior of the girder components (flanges, web and stiffener) at ultimate limit state. Initial geometrical imperfections, plastic material behavior and large deflection effects are considered in the model. For the numerical model validatio n, the computer results from the simulations are compared with experimental results taken from the literature. A parametric s tudy was carried out in order to investigate the influence of t he applied bending moment and the relative location of the stiffener on th e ultimate strength to patch loading. 2015 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49635366014 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.189 Vol.82 |
