摘　　要：在前期试验和理论研究的基础上,将密肋壁板结构中的密肋复合墙板等效为整体斜撑,提出结构的刚架-等效斜撑力学模型,并结合试验数据确立了该模型主要参数的计算方法及塑性铰的设定。采用该模型对一实际密肋壁板结构进行了Pushover分析并进行了抗震性能评估。结果表明采用该模型是实现密肋壁板结构Pushover分析及抗震性能评估的一种有效方法。According to the previous researches and experiments, the rigid frame-equivalent brace model of a multifibbed slab structure is put forward, in which the multi-fibbed composite slab is equivalent to a whole diagonal brace. Based on the previous tests, the main parameters and the plastic hinge locations of the model are established. By using this model, Pushover analysis and seismic performance evaluation of an actual multi-ribbed slab structure are performed. The results indicate that adopting the rigid frame-equivalent brace model is an efficient way to perform Pushover analysis and seismic performance evaluation of multi-ribbed slab structures.
