摘　　要：为研究狗骨式连接轻钢框架的抗震性能分析方法和设计方法,对两跨两层狗骨式连接轻钢框架拟静力试验试件进行了静力弹塑性分析,节点域用转动弹簧来考虑其剪切变形,采用双线性特性塑性铰,计算结果与试验结果较一致。狗骨式连接轻钢框架具有很好的抗震性能,梁上塑性铰首先出现在翼缘削弱截面处。针对狗骨式连接钢框架的特点,提出了抗震设计建议,推导得出了保证塑性铰出现在翼缘削弱部位的条件。In order to study seismic analysis method and design method of dog-bone connection light steel frame, the push-over analysis of pseudo-static force test specimen of a dog-bone connection light steel frame with two stories and two spans has been carried out. The panel zone was handed as a rotation spring element in order to consider the shear deform-ation of panel zone. Bilinear plastic hinge was used for members. The analysis results are consistent with the results of experiment. The dog-bone moment connection light steel frame performs good seismic behavior. The plastic hinges ap-pear at reduced flange section. The proposal of seismic design is put forward for the dog-bone moment connection steel frames. The requirement ensuring the plastic hinges appear on reduced flange section is obtained.
