ANÁLISIS COMPARATIVO ENTRE UN PROCEDIMIENTO PARA ESTIMAR EL EFECTO DE LA TORSIÓN ACCIDENTAL Y SIMULACIONES MONTE CARLO, EN EL MARCO DEL ANÁLISIS PASO A PASO NO LINEAL DE EDIFICIOS

Abstract

A comparative analysis between the responses obtained with two procedures that consider the accidental torsion on the dynamic nonlinear analysis of buildings is presented. The first one involves the use of typical values of accidental eccentricities used in design process. The second procedure involve the variation of parameters that incise in the accidental torsion by means Monte Carlo simulations. The comparison is performed from the responses obtained, measured in terms of concentrated inelastic deformations and lateral distortions. In the study two models of multi-level symmetrical buildings are considered. The CANNY-E program is used for the nonlinear dynamic analysis of the proposed structural models. The results suggest move the position of the center of mass a distance equal to 0.05b to consider the effect of accidental torsion on the dynamic nonlinear analysis of buildings
