摘　　要：为考察网壳结构在地震作用过程中各项耗能与网壳破坏之间是否存在内在联系,对网壳结构的耗能机理进行了研究。首先推导了地震作用下单层网壳结构各项耗能的计算方法,结合具体网壳结构分析了不同峰值的地震波作用下各项耗能的变化规律,并与位移和塑性杆件数两项指标进行了比较,最后讨论网壳破坏时各项耗能呈现的规律性特征。To find out the relationship between the energy dissipation and lapse of latticed shell structures under seismic action, the research on energy dissipation mechanism of single layer latticed shell structure was carried out. At first, the calculation method of all kinds of energy were deduced. Then, the changing law of these kinds of energy were analyzed taking a practical single layer latticed shell structure as example, and the compare with other two indexes, displacement and sum of plastic bars were discussed. At last, some typical characters of these kinds of energy in the course of lapse of single layer latticed shell structure were analyzed.
