Avaliação numérica da rigidez de vigas mistas de madeira e concreto sob carregamento cíclico

Abstract

In this paper was evaluated, using the software ANSYS, the stiffness (EI) of the log-concrete composite beams, of section T, with connectors formed by bonded-in steel rods, type CA-50, disposed in X, with application of cyclical load. The stiffness of the systern was evaluated through the simulation of bending tests, considered 1/2 beam, with cyclical shipment varying among 40 % and 5 % of the strength of the connection with the load relationship R=0,125, for a total of 10 load cycles applied. The numeric results show a good agreement with experimental tests. © Universitat Politècnica de Catalunya, Barcelona, España 2010.
