本文提出了原型结构抗震能力的间接估计法。根据振动台试验结果确立的结构物理参数、对电厂、变电所的主控制楼和配电置装楼进行了各种复杂背景条件下的抗震性能分析,并在此基础上对两类结构房屋作出了抗震性能的评定。 This paper presents an indirect estimation of the seismic capability of a prototype structure. According to the structural physical parameters established by the results of the shaking table test, the seismic performance analysis under various complex background conditions was performed on the power plant, the main control building of the substation and the power distribution and installation building, and on this basis, the two types of structural housing The evaluation of seismic performance was made.
