［摘要］晉中市檔案館由于存在分塔、大跨度連體、樓板不連續(xù)、平面不規(guī)則等超限復(fù)雜項，對結(jié)構(gòu)進(jìn)行性能化抗震設(shè)計及彈性時程分析、模擬中震分析和大震動力彈塑性時程分析。結(jié)果表明，結(jié)構(gòu)整體指標(biāo)、關(guān)鍵構(gòu)件和一般構(gòu)件均能滿足預(yù)設(shè)的抗震性能目標(biāo)。針對結(jié)構(gòu)具有的扭轉(zhuǎn)不規(guī)則及以上平面不規(guī)則等抗震不利情況，對大震彈塑性分析揭示的結(jié)構(gòu)薄弱部位進(jìn)行了相應(yīng)加強(qiáng)措施，如提高關(guān)鍵剪力墻抗震等級，在墻體端部設(shè)置鋼骨，連體部分樓板均雙層雙向配筋，有效保證了結(jié)構(gòu)的抗震安全。

Abstract:Due to the out-of-code complexity of tower separation, large-span connection, slab discontinuity and plane irregularity, the performance-based seismic design and elastic time history analysis, simulated moderate earthquake analysis and large earthquake dynamic elastic-plastic time history analysis were carried out on the structure. The results show that the overall structural index, key components and general components can meet the preset seismic performance targets. In view of the unfavorable anti-seismic conditions of the structure, such as torsional irregularities and irregularities in the above plane, corresponding strengthening measures were taken for the weak parts of the structure revealed by elastoplastic analysis of rare earthquake, such as improving the seismic grade of the key shear wall, setting steel bars at the end of the wall and double-layer two-way reinforcement for the connecting part of the floor, which effectively guarantees the seismic safety of the structure.
Keywords:out-of-code structure; aseismic performance-based design; large-span connection； steel truss
