【摘要】 用位移法计算连续梁、对称性荷载作用下的单跨多层刚架，总刚度阵为对称三对角阵。对多跨多层刚架在竖向荷载或在水平荷载作用下的位移、内力计算，也可用三对角阵形式的总刚得到近似结果。由于位移法方程组形式简单，应用给出的计算公式，无论采用手算或编成简单程序由机算完成，计算工作量都不大，适合初步设计阶段的计算。更多还原

【Abstract】 Calculating the continuous beam,frame of single-span and multi-story by deflection method,the stiffness matrix is symmetrical three-diagonal.For the deflection of multi-span and multi-story frame under horizontal or virtical load,the symmetrical three diagonal matrix,also can be used to get approximate results.With the simple expression of the deflection method equation group, there are no heavy calculation by hand of by simple program.Therefore this method is applicable to the preliminary design.更多还原
