摘　　要：为了分析预应力筋的布置情况对节点受力性能的影响,本文采用ANSYS软件模拟预应力混凝土宽扁梁框架边节点在弹性阶段的试验过程,从宏观上分析其受力性能,并与普通钢筋混凝土试件进行对比。分别以预应力筋全部穿柱、部分穿柱以及全不穿柱为参数进行模拟,将模拟结果与相应的试验结果进行比较分析,误差较小,与试验结果相吻合。In order to analyze the arrangement of prestressed reinforcement to node stress performance,this paper uses the ANSYS software to simulate the test process of prestressed concrete wide-flat beam frame exterior joint in elastic stage,analyze their stress performance from macroscopy,and compare with ordinary reinforced concrete specimens.With prestressed tendons all wearing column,partially wearing column and not wearing column respectively as the parameters for simulation,there are small error between the simulation results and the corresponding experimental results,which coincides with experimental results well.
