［摘要］東莞天利中央花園為部分框支剪力墻結(jié)構(gòu)體系，厚板轉(zhuǎn)換,具有樓板局部不連續(xù)等多項不規(guī)則。根據(jù)結(jié)構(gòu)特征、構(gòu)件的部位和重要程度以及開發(fā)商的需求，針對不同設(shè)防水準(zhǔn)的地震作用，制訂了一系列抗震性能目標(biāo)。對薄弱連接板和轉(zhuǎn)換厚板，采用中震承載力極限狀態(tài)設(shè)計法。使用SAP2000進行靜力非線性分析，用能力譜法進行性能評估。結(jié)果表明，薄弱連接板、轉(zhuǎn)換厚板和框支柱等都能滿足大震不屈服的性能目標(biāo)。

Assessment of seismic performance for Dongguan Tianli Central Garden

Fu Changsheng, Zhang Xiaoyong, Ju Jin, Zhou Lilang(Shanghai ChinaFu Structural Design Inc., Shanghai 200011, China)

Abstract:Dongguan Tianli Central Garden consists of tall residential buildings of frame-supported concrete walls with several irregularities, characterized by thick transfer plate and floor slab discontinuity. Depending on structural features, importance of occupancy and needs of developers, seismic performance objectives were reasonably selected corresponding to the seismic levels. The transfer plate and weak-linking slab were designed by the ultimate strength design method under medium earthquake. The performance of structures was assessed by the capacity spectrum method under the maximum considered earthquake. The pushover analysis results by SAP2000 show that the key members such as the transfer plate, weak-linking slab and frame-supporting columns did not yield with respect to the performance point.

Keywords:performance-based assessment ; ultimate strength design under  medium earthquake; un\|yield during strong earthquake
