摘要
针对目前Matlab有限元程序向量化程度不高的状况,综合运用Matlab内置函数、向量下标、逻辑数组等,给出刚架单元静力分析主要环节的向量化程序代码。这些代码简洁、高效,涉及后处理法和先处理法中结构刚度矩阵集成、结构荷载列阵集成及支承条件处理等,并已通过Matlab运行验证,能够同时用于平面刚架和空间刚架,也可直接或经适当修改用于其他有限元程序。
Considering lack of FEM vectorization programming with Matlab at present,the vectorization codes,with respect to main links of FEM static analysis with frame elements in post and pre treatment methods,have been written based on comprehensive application of built-in functions,vector subscript and logic array,etc.These codes are concise and efficient,concerned with assembling of structure stiffness matrix and load vector and treatment of support conditions.They have been verified with Matlab and can be used in both plane frames and space frames,or in other FEM programs directly or with appropriate modification.
