摘要
根据体外预应力混凝土简支梁的受力特点和工程上的精度要求,结合实践,对体外预应力混凝土简支梁数值分析中的本构关系、迭代思路、判敛原则和死循环的处理四个问题进行了讨论,并得出了相关的定性结论,以真正把握体外预应力结构的受力机理。
According to the characteristic and the precision request of engineering,this paper discusses some issues in the numerical analysis of the simple-supported concrete beams.The issues are the constitutive relationship,the iterative method,the convergence principle,and the dealing with dead cycle.Through the discussion,some qualitative conclusions have been drawn,in order to grasp the forcing principles of outer prestress structure.
