摘要 为了将非均匀各向异性类桁架连续体离散化为工程实际需要的杆系结构,分析了类桁架结构的性质和集中杆的确定方法,建立了类桁架结构的离散化方法.算例显示:采用先构造类桁架连续体,再离散化为杆系结构的方法是可行的,得到非常接近解析解的结果. The non-uniform anisotropic truss-like continuum was discretized to truss structure required in engineering. Based on the analysis of the character of truss-like structure and the technique to locate the concentrated members, the method to discretize truss-like continuum was established. Numerical examples illustrate that it is feasible that truss-like continuum is established first, and then it is discretized to form truss. Its result is very Close to analytical solution.
