以某在建高位大悬挑结构为原型，提出并建立了高位大悬挑结构的力学模型。通过罕遇地震时程分析了该结构的抗震性能，比较了基于力的静力弹塑性分析、基于位移的静力弹塑性分析和 MPA法在该类不规则结构抗震计算的准确性。

In this paper,a mechanical model of high level cantilever structure is proposed and established based on the prototype of a high level large-span cantilever building which is in construction.The seismic performance of this type of the structure is conducted through time history analysis in rare earthquake events. The accuracy of the pushover analysis based on force control patterns、displacement control patterns and as well as the MPA(Modal Pushover analysis)are addressed and discussed by comparing the results with the time-history analysis results.
