摘要
钢板阻尼墙抗震性能好,设计自由度大,在工程中使用越来越多。为了更高精度地模拟钢板阻尼墙的力学性能,提出基于Bouc-Wen模型的模拟分析方法。给出一种基于Bouc-Wen模型钢板阻尼墙参数辨识方法,根据试验数据和仿真结果的验证对比,文中提出的模拟方法可以较好地反映钢板阻尼墙的的力学性能曲线。该模拟方法可得到较好的仿真效果,对实际工程设计分析钢板阻尼墙对结构的抗震性能影响有高精度、数据化的帮助,可为进一步工程应用和设计分析提供参考。
Steel damping wall shows good seismic performance and engineering design freedom, so it is applied with the popularity in engineering. In order to simulate the mechanical properties of steel plate damping wall accurately, this paper presents the new simulation method of Bouc-Wen Model. This paper presents a method based on the Bouc-Wen model to identify the parameters of Steel damping wall. The Comparison of experimental data and simulation results show that the proposed simulation method can reflect the mechanical properties of the steel damping wall. This indicates that the simulation method gives better simulation results, and it gives the actual engineering design analysis of the structure with steel damping walls a high-precision, data-oriented help, which provides a reference for further engineering analysis and design applications
