本文提出将无粘结预应力筋的拉力与结点位移一并作为待求列矢的非线性有限元法，可避免以往研究中采用的繁复迭代运算。对水平荷载作用下的无粘结预应力混凝土框架进行分析的过程和结果，证实了这种方法的有效性及其对试验结果良好的预测精度。
In this paper, the non-cohesive prestressed tendons’ tension and joint displacement are regarded as nonlinear non-linear finite element method, which can avoid the complicated iterative calculations used in previous studies. The analysis process and results of unbonded prestressed concrete frames under horizontal loads confirm the effectiveness of this method and its good prediction accuracy for test results.
