| Abstract: | On the basis of the theorem of structure continual variation of truss structure, the second theorem of that for evaluating the displacement during the variation of the structure was derived. The continual generation of limit state function was realized by using the method of numeric analysis and recurrence formula. Repeated assembly of the global stiffness matrix and repeated inverse operation of the matrix was avoided, and the calculation efficiency was improved obviously. |
