| 摘 要： | 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。

| Abstract: | The deformations of the unbonded prestressed concrete frameworks are analyzed by using the nonlinear FEM, by which a bar is divided into segInents and a section into layers. Taking the foree eqUilibrium and deformation compatibility into consideration, the unknown displacements of the structureas and the tensile forces in the unbonded tendons can be solved simultaneously without the time-consuming iteration as used in the conventional procedure. The analytical results agre well with the test ones. |
