摘要
针对预应力的施加方法———等效降温法和初应变法中存在的预应力损失问题,其影响了计算精度,介绍了用生死单元法来解决这一问题,通过实例分析,证明了该方法在求解这类结构方面的可行性。
A new type of structure（beam string structure） is introduced in this paper and ANSYS software is used to nonlinear analysis. The method of killing activating elements is proposed here to avoid the prestressed loss. The correction and rationality of the method is proved by calculation and analysis of a simple structure.
