［摘要］基于動(dòng)力彈塑性分析,介紹了三個(gè)大跨度場(chǎng)館的大震下安全度評(píng)價(jià)和優(yōu)化設(shè)計(jì)，通過(guò)對(duì)核心筒和鋼構(gòu)件截面的優(yōu)化，形成合理的結(jié)構(gòu)破壞模式，達(dá)到節(jié)省鋼材并減少剪力墻和主要受力構(gòu)件在大震下塑性屈服的目的。大震下動(dòng)力彈塑性分析不僅為第二階段設(shè)計(jì)提供了驗(yàn)算手段，同時(shí)也為第一階段結(jié)構(gòu)設(shè)計(jì)優(yōu)化提供了依據(jù)。

Abstract:Based on the elastic-plastic dynamic analysis, the evaluation of the safty degree  under strong earthquake and the optimization of the structural scheme of three large-span gymnasiums  are introduced. The optimization of core tube and the cross-section of steel members is advantaged to form the rational failure mode， save steel and reduce the shear wall and the main component plastic yield under strong earthquake. The elastic-plastic dynamic analysis under strong earthquake not only provides a means of checking for the second phase of design，but also plays the role of providing the reliable data for structural optimization.

Keywords: elastic-plastic dynamic analysis; large-span gymnasiums; failure mode; optimal design
