Modelación numérica de columnas a flexo-compresión sometidas a cargas cíclicas, utilizando pruebas de cargas de la Universidad de California y el programa SeismoStruct

Abstract

The academic paper presents the numerical modeling of reinforced concrete flexural-compression columns subjected to cyclic loads was realized using three load tests of the University of California for each type of connection (Cantilever, double curvature and double ended), in addition, each of them comprised three simulations for each of the steel constitutive models (Menegotto Pinto - stl-mp, Monti Nuti - stl-mn, Ramberg Osgood - stl-ro) and three types of concrete constitutive models (Chang Mander - con_cm, Mander - con_ma, Kapos and Konstantinidis - con_hs), from wich, eighty one pillar modeling generated by SeismoStruct software are obtained that will be compared with the database of the Pacific Earthquake Engineering Research Center (PEER). The results indicate that the best model to reproduce the behavior of the columns is the Mander concrete with Menegotto Pinto reinforcement for cantilever and double curvature connections, however, Kappos Konstantinidis being a model developed for high strength concrete, produced good results in combination with the reinforcement of Menegotto Pinto for the double ended connection.
