该文利用Open Sees对一座三层带黏弹性阻尼器钢框架结构进行振动台试验的数值模拟,以此验证黏弹性阻尼器力学模型及分析方法的正确性。首先介绍了振动台试验,总结了黏弹性阻尼器耗能特征及减震效果;然后利用Bouc-Wen模型模拟黏弹性阻尼器的力学性能,在Open Sees中进行非线性动力时程分析模拟振动台试验;最后将数值模拟结果和试验结果进行对比分析。结果表明,模拟结果和试验结果在结构动力特征和结构响应上均吻合良好,因此验证了黏弹性阻尼器力学模型及分析方法的正确性。
This paper uses Open Sees to simulate the shaking table test of a three-story viscoelastic damper steel frame structure to verify the correctness of the viscoelastic damper mechanical model and analytical method. Firstly, the shaking table test is introduced, and the energy dissipation characteristics and damping effect of the viscoelastic damper are summarized. Then, the Bouc-Wen model is used to simulate the mechanical properties of viscoelastic dampers. Nonlinear dynamic time history analysis is performed in Open Sees to simulate the shaking table Test; Finally, numerical simulation results and test results were compared. The results show that both the simulation results and the experimental results agree well with the structural dynamic characteristics and structural response, so the correctness of the viscoelastic damper mechanical model and analytical method is verified.
