【摘要】 应用广义图乘法分析荷载与连续梁三弯矩方程关系。若杆内有对称荷载,则三弯矩方程简单;简支梁弯矩图的面积能表示荷载对连续三个支座弯矩的作用。任意荷载的作用含反对称荷载分量的图乘剪力的作用。若杆内荷载是同方向,则反对称荷载比弯矩图面积的影响小。更多还原

【Abstract】 Analyzing relationship between load and continuous beam three moment formula by using generalizied diagram multiplication method.For symmetry load in each span three moment fomula is simpleness.The function from load can shown by simply support beam moment diagram area.For any load the function from load is in multiplication shear force by antisymmetry load.With load in same direction on beam the function from antisymmetry load is smaller than that from area of moment diagram.更多还原
