耗能元件布置对自控耗能UPPC梁受力性能影响研究

The Influence of Energy Dissipating Elements Arrangement on Mechanical Performance of Self-controlled Energy Dissipating UPPC Beams

文章通过有限元软件对耗能元件布置位置的不同以及配置预应力钢绞线根数的不同,对UPPC框架梁受力性能的影响进行分析。随着预应力钢绞线配置数量的增加,梁上表面主压应力最大值增大;随着预应力钢绞线配置数量的增加,梁下表面主拉应力最大值增大,配置两根预应力钢绞线比配置一根预应力钢绞线,所发挥的作用更大。

In this paper,the finite element software is used to analyze the influence of the different positions of energy dissipation elements and the different number of prestressed steel strand on the mechanical performance of UPPC frame beams.The maximum principal compressive stress on the upper surface of the beam increases with the increase of the number of prestressed strand wires.With the increase of the number of prestressed strand,the maximum principal tensile stress on the lower surface of the beam increases,and the effect exerted by two prestressed strand is greater than that of one prestressed strand.
