摘　　要：针对火电厂混凝土主厂房结构难以满足在高烈度区抗震性能的现状,提出一种RC分散剪力墙-SRC框排架的新型混合结构体系。基于1/7比例缩尺的某火电厂RC分散剪力墙-SRC框排架模型结构进行了拟动力试验和拟静力试验。根据试验结果研究模型结构在El-Centro(N-S)水平地震作用下的滞回反应与耗能能力、延性性能和刚度变化。结果表明:研究结构较同类钢筋混凝土框排架结构具有更好的滞回性能和耗能能力,分散剪力墙和型钢混凝土柱对结构延性和耗能能力的提高显著且有较大安全储备。研究为同类结构的抗震设计提供试验依据。The concrete structures for thermal power plants hardly satisfy the requirements for highly seismic regions, a new hybrid structure of＇ RC scattered shear wall-SRC frame is proposed. Pseudo-dynamic and pseudo-static tests are conducted for a 1 ： 7 scaled model structure. According to the test results, the hysteretic response ＆ energy dissipation capacity, ductility ＆ stiffness degradation of the model structure under El-Centro （N-S） horizontal earthquake motion are studied. The results show that the structure has much better hysteretic behavior and energy dissipation capability than traditional reinforced concrete structures, and the scattered shear walls and steel reinforced concrete columns in the model structure obviously improves its ductility and energy-dissipation capacity.
