摘要
闽投营运中心为带四层地下室临近地铁的高层建筑,针对本工程逆作法施工的特点提出了塔楼结构采用框架-支撑芯筒结构体系的方案。通过盈建科和MIDAS BUILDING两种软件对框架-支撑芯筒结构体系进行了多种地震情况下的计算分析,结果表明所采用的结构体系具有多道抗震防线,耗能性良好,能满足规范要求的各项指标,实现了抗震性能化设计,安全合理。并针对相关的设计参数作出了探讨,提出了一些未来有待进一步深入研究的问题。
Mintou Operations Center is a high-rise building with four storey basement near the subway station,a method of using frame-brace core structure was proposed to satisfy the top-down construction technique condition.Programs of YJK and MIDAS BULIDING were used in this paper to analyze the frame-brace core structure under different seismic loads.The result shows that the frame-brace core structure is a safe and appropriate system which has multiple seismic defense lines,good energy dissipation performance,and can satisfy the requirements of codes,and achieve the goals of performance-based seismic design.Some issues regarding to the design parameters and further research are also raised in this paper.
