［摘要］佛山集成金融廣場建筑高度199.88m，為超A級建筑高度建筑。結(jié)構(gòu)設(shè)計采用了框架-核心筒結(jié)構(gòu)，對結(jié)構(gòu)進行罕遇地震下的彈塑性時程分析，檢驗結(jié)構(gòu)在大震下的抗震性能，采用ABAQUS軟件對其進行動力彈塑性分析，研究在預(yù)估罕遇地震作用下結(jié)構(gòu)的非線性動力響應(yīng)，并給出定量評價，包括結(jié)構(gòu)變形特征、樓層剪力、最大層間位移角和剪力墻損傷等。結(jié)果表明，此結(jié)構(gòu)形式具有較好的抗震性能，能夠保證大震不倒的抗震性能目標，整體結(jié)構(gòu)設(shè)計安全可靠。

Abstract: The Foshan Integrated Financial Plaza with architect height of 199.88m is beyond the A-level height limit of the code. The framework core tube is adopted in the structural design. Dynamic elasto-plastic analysis was carried out by sofeware ABAQUS to analyze the nonlinear dynamic responses of the structure. The quantitative evaluations were given including the structure deformation characteristics, storey shear force, maximum interlayer displacement angle and shear wall plastic damages. The results show that this structural form has well seismic performance and can ensure the performance target of not collapsing under rare earthquake. The overall structural design is safe and reliable.
Keywords: out-of-code high-rise building; elastic-plastic time-history analysis; seismic design; ABAQUS
