摘　　要：本文运用有限元分析软件SAP2000对空腹梁上下弦肢高比不同的空腹式巨型框架的抗震受力性能进行地震反应时程分析,比较肢高比对空腹式巨型框架抗震受力性能的影响;通过有限元创建模型分析后表明,当空腹梁上下弦其中一弦的高度确定后,空腹式巨型框架结构的受力性能随着上下弦肢高比的变化而发生变化。具体表现在,当上下弦的高度接近时空腹式巨型框架结构有较好的受力性能。The structural seismic response of time -history analysis were carried on different limb ratio to fasting mega frame structures ,and compared the effects of different limb ratio by using finite ele‐ment analysis software SAP2000 . The results show that the seismic performance of fasting mega frame structures is different to different limb ratio ,and a good force performance obtained with the similar height of the upper and lower chords .
