【Abstract】 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.更多还原
