摘　　要：砌体结构纵向窗间墙在多次大地震中震害严重,其抗震计算可采用不同的方法,为了深入理解砌体结构纵向窗间墙抗震能力,为实际工程纵向窗间墙的抗震计算提供参考,本文用4种计算方法对一实例进行对比分析,结果表明不同方法计算同一片窗间墙抗侧刚度相差较大,但分配地震剪力相差不大。通过归纳4种计算方法的优缺点,优选出两种较为实用、合理的计算方法。Longitudinal walls between windows of masonry were broken down in many great earthquake,and differential methodes were given for seismic calculation.Comparison and analysis with four calculation methods for a true example were given,which can make us understand the seismic capacity of longitudinal wall between windows of masonry thoroughly,and can provide the references for seismic calculation for longitudinal wall between windows for practical engineering.Results show that lateral stiffness of the same wall between windows has big difference,while the distributive seismic shear has small difference.The merits and demerits are concluded in the end,and the method two and four are more applicable and reasonable.
