基于工程实例对越层柱长度系数的分析与思考

The Analysis and Thinking of Length Coefficient of Skip-floor Column Based on Certain Project

主要利用MIDASGEN对某工程越层柱进行了屈曲分析,通过模态分析结果以及压杆稳定理论反推出越层柱的长度系数,利用计算出的长度系数对PKPM的越层柱长度系数进行复核,保证了工程的安全性。结果表明,带横向约束的越层柱的实际长度要比理论长度小很多。

This paper mainly uses the buckling fuction of MIDAS GEN to analyse the skip-floor column of one project. Through using the results of modal analysis and the buckling theory ,I have calculated the length coefficient of skip-floor column, and I review the calculated coefficient of PKPM to ensure the engineering safety. The results show that the length the skip-floor column with lateral constraint than the theoretical length is small.
