某超限高层框架一核心筒结构抗震分析

Seismic Analysis of a High-rise Overrun Frame Core-tube Structure

某项目工程采用框架-核心筒结构体系，存在楼板局部不连续超限问题，工程设计时选用SATWE、PMSAP、ETABS程序进行了多遇地震、设防地震以及罕遇地震作用下的抗震分析和性能化设计。相关计算结果表明，结构设计成功解决了结构超限问题，达到了预定的性能目标，满足了三水准抗震设防要求，本工程结构体系和构件具有较好的抗震性能和安全储备。

Seismic analysis of a project using high-rise overrun frame core-tube structure was studied. The programs of SATWE, PMSAP and ETABS procedures were applied to carry out the structural seismic analysis and the Performance-based design of various earthquake actions in the whole designing process. With the overrun problems such as torsional irregularity, characterized by floor partial discontinuous and lateral stiffness varying in vertical direction were settled, the scheduled performance objectives and the three-level earthquake fortification objects were achieved. The numerical computation results show that this structural system is safe and reliable.
