摘要
根据余能等效的原则，将板壳连续体转化成空间杆系计算模型，推导了计算公式，这样很好地克服了板、壳单元体在形函数的选择及连接条件上所遇到的困难，从而可以利用已经普及的空间刚架程序来计算板壳及其组合结构。给出了计算实例并与其它方法进行了比较。
In this paper, calculation formulas and model are developed for space bar systems which are the division of nonindividual body of plates and shells based on the law of complementary energy equivalence. In this way, we can successfully overcome the difficulties which are encountered in choosing shape functions for plates and shells, and make use of programs for space stiff frames to compute the composite structures of plates and shells. Finally some practical examples by using this method are given and this method is proved correct by the comparison with other methods.
