摘要
分析了材料力学传统方法建立拉(压)超静定杆系的变形协调方程的困境,提出了利用结构中某些点的几何共性参数建立变形协调方程的方法,通过算例验证了本方法的正确性及有效性,通过比较,本方法具有明显的优越性,可以相当方便地求解超静定杆系。
In this paper,the inconvenience of the traditional method in mechanics of materials to establish the deformation compatibility equation of statically indeterminate bar system is analyzed.the new method by using the geometric common parameter in some points of structure to establish the deformation compatibility equation is proposed.the examples are taken to illustrate the validity and the availability of this new method.by comparison,this method has obvious advantages,can convenient to solve the problem of statically indeterminate bar system.
