Jianzhu Gangjiegou Jinzhan预应力撑杆构件造型优美、省材高效，但由于其柔度较大，易产生多个屈曲模态交互耦合即“交互屈曲”模式的破坏，且交互屈曲对其极限承载力、屈曲性能影响显著。研究了交互屈曲对预应力对称、不对称撑杆构件轴压、压弯作用下的屈曲性能、极限承载力影响，并据此采用基于回归算法的人工神经网络建立了其极限承载力估计模型。研究结果表明，对于预应力撑杆构件，模态交互易造成不稳定后屈曲，且对其极限承载力有显著的削弱效应；该削弱效应是否产生影响由结构几何参数与参与交互的模态屈曲荷载决定，其削弱程度受结构撑杆不对称性、预应力水平影响 ...

Jianzhu Gangjiegou Jinzhan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 ...
