摘要
研究了受弯构件的弯扭稳定问题。首先介绍了求解受弯构件临界弯矩中系数的理论方法,研究了与弯扭稳定相关的有限元法,最后利用有限元程序拟合出了跨中等间距布置2至4个横向荷载的受弯构件的β1、β2、β3系数。
It is investigated the buckling of the member in bending.First it is introducesd the academic method of getting the critical bending moment's coefficients of the members in bending,then FEM is explained.At last the coefficients β_1、β_2、β_3 of the formula under two to four vertical loads are fitted by FEM.
