基于ABAQUS二次开发的RC框架结构屈服机制
The RC Frame Structure Failure Mode Based on ABAQUS Secondary Development
摘要
Abstract
In order to study the failure mode of the cast-in-place RC frame structure under horizontal load, the accuracy of the nonlinear fiber beam element which is suitable for ABAQUS software is verified first. Then, regular RC frame structures and RC frame structures with monolithic slab are established separately to analyze the structural deformation patterns, the internal forces of frame beams and columns and the effective flange width at the tension zone of the frame joints. Numerical results indicate that it is difficult for the RC frame structure with monolithic slab to achieve the failure mode of “strong column-weak beam”. Besides, the slab rebar force and the effective flange width at the tension zone of the frame joints become greater as the frame displacement increases. What’ s more, the effective flange width at the tension zone of the frame joints cannot be approximated suggested as 6 times slab thickness, lateral displacement and other seismic fortification intensity should be taken into account.关键词
