［摘要］臨沂華潤中心項目萬象匯商業(yè)部分地下2層，地上5層，結(jié)構(gòu)高度28-60m，經(jīng)過方案對比，最終采用了帶消能減震技術(shù)的框架結(jié)構(gòu)。利用YJK和MIDAS/Gen等軟件進行了反應譜分析及小震彈性時程分析計算。結(jié)果表明:結(jié)構(gòu)的周期比、層間位移角等均滿足規(guī)范要求。并利用PKPM/Sausage軟件對結(jié)構(gòu)進行動力彈塑性分析，分析結(jié)果表明，框架+消能減震結(jié)構(gòu)體系的抗震性能良好，在高烈度區(qū)采用框架+消能減震結(jié)構(gòu)是一種可行的辦法。

Abstract:Wanxianghui commercial part in Linyi China Resources Center project has 2 floors underground and 5 floors above ground. It has the structural height of 28-60m. After scheme comparison, the frame structure with energy dissipation technology was adopted finally. YJK and MIDAS/Gen software were used to conduct the reaction spectrum analysis and elastic time-history analysis under frequent earthquakes. The results show that the period ratio and inter-layer displacement angle of the structure meet the requirements of the code. And the software PKPM/Sausage was used to conduct dynamic elastic-plastic analysis of the structure. The analysis results indicate that the seismic performance of frame structure with energy dissipation system was good, and it is a feasible method to adopt frame structure and energy dissipation structure in high seismic fortification intensity area.
Keywords:energy dissipation system; buckling-restrained brace; shear damper; dynamic elastic-plastic analysis
