摘要
分别用两种解析模型研究了等效拉延筋约束力的计算过程,一是基于能量原理的改进Stoughton模型,二是对李东升等提出的直接法解析模型进行改进。同时对两种模型的基本假定进行了调整和补充,使两种方法的前提条件一致,并编制程序计算了在相同变化条件下的约束力,根据两组结果数据的对比及部分数据与实验结果的比较,从实验与计算两方面证明了用解析方法模拟等效拉延筋约束力的可行性。
During the process of solving the questionabout the Drawbead Restraining Force (DBRF), we adopttwo methods: one is to achieve the DBRF by the im-proved Stoughton Model, the other for obtaining theDBRF is to use the model which is put forward by Dong-shen Li etc. and improved by us (we call this method theDirect Method). In this paper,we have provided the com-mon premise of the two models. Therefor,in the practical application, we have proved the feasibility of both meth-ods by calculations and experiments.
