| 摘 要： | 采用抗震规范中薄弱层的验算方法,对钢筋混凝土框架结构的薄弱层进行确定和对比分析,通过分析框架柱轴压比对框架结构破坏形态和延性的影响,提出现行抗震规范轴压比限值偏高是导致框架结构破坏的主要原因,通过调整框架柱截面尺寸,控制其大偏心受压破坏范围,可提高建筑结构的抗震能力.

| Abstract: | Based on seismic method of calculating the weak layers of reinforced concrete frame structure,the weak layer is determined and comparative analysis is carried out.The influence of the axial compressive ratio of frame column frame structure damage pattern and ductility are analysed.The current seismic code＇s limit value of the axial compressive ratio is high which mainly leads to frame structure failure.By adjusting the change of frame column section size and controling the large eccentric loading range of destruction,the aseismic capacity of building can be improved. |

| Keywords: | frame structure the axial compression ratio weak layer |
