［摘要］通辽图书馆项目存在楼板局部不连续、侧向刚度不规则、扭转不规则、尺寸突变、局部不规则等多项不规则，属超限工程。针对超限特点，采用PMSAP和MIDAS/Gen两种软件，对主体结构进行了多遇地震、设防地震和罕遇地震作用下的性能分析，从计算结果来看，结构抗震性能良好，主要控制指标均满足规范要求。基于性能化抗震设计，根据构件的重要性提出不同的性能化目标，采取相应的加强措施。

Abstract:There are multiple irregularities in the out-of-code project of Tongliao Library such as local floor discontinuity, irregular lateral rigidity, irregular torsion, size mutation and local irregularity. According to the out-of-code characteristics, two kinds of software including PMSAP and MIDAS/Gen were used to conduct performance analysis of the main structure under frequent earthquake, fortification earthquake and rare earthquake. The calculation results show that the structure has good seismic performance and the main control indexes can meet the requirements of specification. Based on performance-based seismic design, different performance objectives were put forward according to the importance of the components, and corresponding strengthening measures were taken.

Keywords:Tongliao library; out\|of-code; irregularity; dynamic elasto-plastic analysis; performance-baced seismic design
