Performance-based Seismic Design Of A High-rise Architecture

High-rise construction in recent years has been more concern, the construction and applications are increasingly common. China’s "high regulation" for super high-rise performance-based seismic design requirements raised a total of A, B, C and D of the four goals, than before the traditional norms of seismic design guidelines for the actual project owners have greater economic demand reference room and performance requirements.In this paper, Nanchang area overrun a high level, for example, proposed in A, B, C and D performance objectives, the project required to achieve the performance levels instance quantitative indicators related to capacity and displacement, the use of the EPDA and SATWE Overrun high-level modeling and analysis, calculated from the set parameters, the structure index, selection and other aspects of seismic waves using modal response spectrum method(CQC method), elastic dynamic time history analysis, nonlinear time history analysis when power and so the overall engineering calculation and analysis, design satisfy the four structural seismic performance targets A, B, C, D, and proves the design methods used practical operability can be used as a future super high-rise design Ways and reference. Another study by the above design for the "high regulation" provides seismic performance targets A, B, C, D, 6 degrees fortification area, proposed a design efficiency of design: to design a structure to meet the performance objectives under rare earthquake bearing performance level achieved, and then through several revisions member, checking the structure in the case of multi-bearing capacity and displacement indicators earthquake and fortification intensity earthquake, so that the resulting structure to achieve the appropriate level of performance requirements.Finally, the ratio of the economy, the size, the amount of reinforcement four structural aspects of discovery, seismic Objective C is an ideal choice for the owners, which is consistent with a large selection of C actual project objectives, as this provides practical rationality based selection.
