[摘要] 本工程緊鄰主廠房，而主廠房是與核安全有關(guān)的I類物項(xiàng)，需對(duì)其在極限安全地震動(dòng)下的變形性能進(jìn)行驗(yàn)算。通過靜力彈塑性分析方法，采用SAP2000的纖維鉸模型對(duì)結(jié)構(gòu)的彈塑性進(jìn)行模擬，從而得到結(jié)構(gòu)在極限安全地震動(dòng)下各構(gòu)件截面不同位置處材料的應(yīng)力應(yīng)變發(fā)展情況。本文采用的方法可供同類工程設(shè)計(jì)時(shí)參考和使用。

Abstract: This project is near by the main power house which is I type item relate to nuclear safety, therefore checking computation of the mechanical performance under the ultimate safety ground motion is necessary. This paper carries out static pushover analysis by the fiber hinge in SAP2000 to simulate the elastic-plastic response, resulting in the stress and strain of the materials in the different place of each component under the ultimate safety ground motion. This method can be a reference for the engineering designers to design this kind of structures.
Keywords: nuclear project; ultimate safety ground motion; static pushover analysis; fiber hinge modal
