摘要
推导了曲线箱梁剪滞效应的基本微分方程,据此求得不同支承条件及荷载型式的剪切位移f(φ)的解,从而得到各种情况的剪滞系数及有效宽度比的计算公式,最后,探讨了曲线箱梁剪滞效应随跨宽比L/2b、径宽比R0/2b等的变化特性。
The fundamental differential eguation of shear-lag effect is derived,and the solutions of shear displacement f(φ)under different conditions of supports and loads are deteimined, using thesolutions,the formula of shear-lag coefficient and effective width ratio are obtained. Finally,theshear-lag effect for different porameters is investigated.
