Then , author introduces geometric nonlinear analysis theory , geometric nonlinear calculation theory during construction period , load position of live load considering geometric nonlinear and calculation theory of worst - case value , static time history theory for vehicle running , geometric nonlinear analysis theory of natural vibration and structural dynamic reaction and so on . all of these theories fit any appointed structure with corresponding programs . so a series of completed analysis approaches that cover all geometric nonlinear factors of bridge structure are formed 其次,介紹了對任意指定結(jié)構(gòu)的幾何非線性分析原理、施工階段幾何非線性計算原理、考慮幾何非線性的活載加載位置與最不利值的計算原理、車隊行駛靜力時程分析原理、非線性結(jié)構(gòu)的自振特性和結(jié)構(gòu)動力反應(yīng)分析原理等,其中包含了相應(yīng)的計算程序模塊的編制方法,形成了一整套考慮橋梁結(jié)構(gòu)所有幾第日頁西南交通大學(xué)博士研究生學(xué)位論文何非線性因素的橋梁結(jié)構(gòu)分析方法。
