摘　　要：为了对半刚性连接钢框架进行更好的抗震设计以及加快其在工程中的应用,本文对两种不同质量的T型钢连接钢框架模型进行了拟动力试验,通过对比分析两种钢框架在地震作用下的应变、位移和荷载的变化情况以及滞回性能,研究质量对T型钢连接钢框架抗震性能的影响。试验结果表明:在一定范围内,T型钢连接钢框架模型的质量对其动力反应和抗震性能有较大的影响,减小钢框架的质量对抗震有利,同时在进行抗震设计时要考虑其合理性和经济性。In order to better design and accelerate the application of semi - rigid connection steel frame in seismic engineering , pseudo dynamic test for two kinds of different mass of T steel connection steel frame models was carried out. Through contrast analysis of the change of strain, displacement , load and hysteretic performance for the two kinds of steel frame under the same earthquake, we studied the effect of mass on seismic performance of the T steel connection steel frame . Experimental results showed that , in a certain range, the mass of the T steel connection steel frame model had a great influence on the dynamic response and seismic performance that decreasing the mass could be contributed to resistanting the earthquake , at the same time , the rationality and economy should be considered in the seismic design.
