钢-混凝土组合梁桥在满足使用性能的同时也会发生疲劳损伤，在桥梁设计和使用阶段应保证桥梁不发生疲劳破坏。为研究不同因素对桥梁疲劳损伤的影响，选取一座双工字钢-混凝土组合连续梁桥，采用车桥耦合分析程序对不同的车速、车重、桥面不平整度、桥面板厚度和主梁腹板高度下主梁的疲劳损伤进行分析。首先计算不同影响因素下桥梁的动应力，分析应力幅和等效应力幅个数的变化规律；然后分析应力幅冲击系数随各影响因素的变化规律；最后分析不同影响因素下主梁疲劳细节位置的疲劳损伤。研究结果表明：车重 ...

负弯矩区采用RPBL连接的钢-混凝土组合梁高温下截面塑性铰演化研究
Jianzhu Gangjiegou Jinzhan为探究高温环境下采用RPBL（Rubber-Ring Perfobond Leiste）连接件的钢-混凝土组合梁在负弯矩区塑性铰的形成机理，本文建立了该类组合梁在火灾条件下的数值模型。通过分析组合梁支座截面应力的演化过程，研究了不同温度条件下负弯矩区的变形特征。此外，重点考察了底部钢梁翼缘宽厚比、腹板高厚比以及混凝土板厚度与截面总高度之比等关键参数对塑性铰形成的影响。研究结果表明：在高温作用下，负弯矩区RPBL连接件组合梁的混凝土板内钢筋及下部钢梁的纵向应力随温度升高而逐渐衰减。此外，底部钢梁翼缘宽厚比、

, 2007 橋梁易損性曲線的建立可分為理論分析方法與經驗分析方法。其中理論分析方法又包括非線性靜力分析以及非線性動力分析兩種方法;經驗分析方法則是由震災後所得的橋梁損壞資料統計而得。 本文主要的研究內容為利用SAP2000建立石圍橋的分析模型，再利用理論分析中的非線性靜力分析Pushover Analysis建立橋梁理論的易損性曲線，再進一步利用九二一集集地震的橋梁震害資料所建構的經驗易損性曲線加以驗證。 橋梁模型的建立是理論分析較重要的部分。本研究模擬石圍橋的單柱式橋墩，三跨簡支承PCI梁，假設柱底產生塑角 ...
