摘要
应用迭代法对阶梯式简支梁挠曲线的有限差分方程组进行分析、求解 ,建立有限转角及挠度方程 ,推导了阶梯式连续梁的有限挠度方程及有限三弯矩方程 ,并据该方程进行了弯曲刚度分析 ,得到足够精确的结果 。
By analyzing the set of finite difference equations of the deflection curve of continuous simple-supported beam,the three-moments of rotation and deflection are established.Then the finite three-moments equations and finite deflection equations of continuous ladder beam are derived.Based on these equations,sufficient accurate results of stiffness analysis can be obtained,so a very practical method of engineering computation is supplied.
