摘  要:采用一种罚单元处理有限元法分析板梁组合结构连接处单元节点不重合的过渡问题。编制了有限元程序,把这种罚单元作为一种单元类型组装到程度中去;而SAP5程序对板梁单元节点不重合问题采用主从关系。用这二种方法计算实例。In this paper,a penalty element has been used to treat the problem for the link of element modes in using the Finite Element Method to analyse composite elastic structures.The program of the Finite Element Method has been made,and this penalty element can be quite easily assembled into the program as a new element type.However,the SAP5 program uses the mainvice relation to analyse the link of element nodes in composite elastic structures.These two methods have been used to calculate an actual example.The two results are corresponded much better.The penalty element as a joint element has a good advantage of treating the link of platebeam composite elastic structures.
