预应力撑杆构件交互屈曲与承载力智能估计方法

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、不对称撑杆构件在轴压、压弯作用下屈曲性能、极限承载力的影响，并据此采用基于回归算法的人工神经网络（ANN）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；该削弱效应是否会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 ...
