Numerical Simulation Analysis on Influence of Stress States of Slab Reinforcing Bars on RC Frame Beams

Slab reinforcing bars is in different states of stress before earthquake comes because of vertical loads.In order to find out the degree and pattern that slab reinforcing bars contribute to the bearing capacity of main beams in RC frame,a finite element program ABAQUS is used to quest this problem.The three models show that slab reinforcing bars in different states of stress affect the mechanical behavior of main beams.In addition,a suggestion about the arrangement of reinforcing bars of slabs and beams is given in this article.
