| 摘 要： | 采用考虑材料非线性的有限元方法,选取合理的混凝土、预应力筋和普通钢筋的本构关系曲线及其单元类型,对高性能预应力混凝土梁的受力全过程进行了分析计算.研究了张开裂缝剪力传递系数和单元尺寸对预应力混凝土梁受力性能分析的影响效果,通过3根实验梁受力全过程的仿真计算结果与实验结果的对比,表明所采用的ANSYS数值模型技术是合理可行的.

| Abstract: | Based on the finite element method considering the nonlinear property of materials,the rational constitutive model and the element type of concrete,strand and normal reinforcement were selected,the full loading behaviors of high performance prestressed concrete(HPPC) beams were analyzed.The effects of the shear transfer coefficient of open cracks and the sizes of elements on the property of HPPC beams were studied.It shows that the numerical simulation technology using ANSYS presented is feasible after comparing the calculating results with the test results of three HPPC beams. |
