轴压比对RC框架结构“强柱弱梁”屈服机制的影响研究
Study on Influences of Axial Compression Ratios on the “Strong Column-Weak Beam” Yield Mechanism of RC Frame Structures
摘要
Abstract
The values of axial compression ratios have remarkable effect on the realization of the “weak beam_strong column” mechanism. Plenty of studies revealed that high limit axial compression ratio values couldn’ t effectively guarantee the realization of “strong column_weak beam” yield mechanism. The available literature did not provide axial reference compression ratios value range for engineering practice. With the aid of the structural analysis program ABAQUS , by varying concrete grade, different column axial compression ratios without changing stiffness ratios are got. By using elastic_plastic dynamic time history analysis, the axial compression ratios value range is analysed effectively and the realization of“weak beam_strong column” mechanism can be guaranteed. The present study may provide reference for engineering design.关键词
