摘   要：为研究波形腹板正对称阻尼器的滞回性能和抗侧性能，设计两个阻尼器试件分别为横向波形腹板阻尼器和竖向波形腹板阻尼器，并进行拟静力试验. 试验结果表明：波形腹板阻尼器具有良好的滞回性能和耗能能力，竖向波形腹板阻尼器的承载力明显高于横向波形腹板阻尼器;阻尼器的耗能主要是依靠波形腹板的剪切和屈曲，翼缘板对阻尼器的承载力贡献相对较小. 借助ABAQUS有限元软件仿真与试验对比验证，仿真结果与试验结果吻合度较高. 以竖向波形腹板阻尼器为基础，建立22个有限元模型，变化参数为波形腹板的高宽比、厚度和波幅. 结果表明：增大波形板的高宽比，阻尼器承载力大幅度下降;增加波形板的厚度，阻尼器承载力大幅度上升;增加波形板的波幅，对阻尼器的承载力有小幅度提高. 最后，结合有限元算例，推导、拟合得出了波形腹板阻尼器的抗剪承载力公式.

Abstract：In order to study the hysteretic performance and lateral resistance of positive symmetrical damper with corrugated web， two damper specimens， horizontal corrugated web damper and vertical corrugated web damper， were designed， and their quasi-static tests were carried out. The test results show that the designed corrugated web dampers have excellent hysteretic performance and energy dissipation capacity， and the bearing capacity of vertical corrugated web damper is obviously higher than the horizontal corrugated web damper. Meanwhile， the energy dissipation of the damper mainly depends on the shear and buckling of the corrugated web， whereas the contribution of the flange plate on the bearing capacity of the damper is relatively small. The simulation and experimental verification by ABAQUS finite element software show that the simulation results are in good agreement with the experimental results. Based on the vertical corrugated web damper，a total of 22 finite element models are established， with variable parameters including the aspect ratio， thickness and amplitude of the corrugated web. The results show that with the increase of the aspect ratio， the shear bearing capacity decreases greatly; with the increase of the thickness， the shear bearing capacity increases sharply; with the increase of the amplitude， the shear bearing capacity increases slightly. Finally， combined with the finite element models， the shear bearing capacity formula of the corrugated web damper is derived.
