摘　　要：在解算超静定刚架时,系数和自由项多,计算量大,内力图多。根据力学方法,运用数学变换,基于Matlab大型数学计算软件,给出了刚架的一种算法,分步编制了横杆和竖杆的计算和绘图程序。Matlab的这一应用减少了计算量,提高了绘图质量,拓展了Matlab在力学中的应用范围,在结构力学计算和绘图中具有普遍的适用性。To resolve statically complex indeterminate rigid frames is a large amount of work to calculate the coefficient and free terms.As a large-scale mathematical computation software,Matlab programming can be used to solve this problem step by step.A calculation method of rigid frame is proposed.Methods of calculation and drawing of rail and vertical pole are given,and it also can calculate the vertical pole as a rail.Based on the case,this paper presents that Matlab is efficient and convenient in calculating a structural mechanics and can be applied to many kinds of structures.
