建筑工业化的发展促进了钢结构和装配式构件的发展,其中防屈曲耗能支撑因其良好的抗震性能被广泛使用。为了实现更好的工业化生产和现场装配,以及提高其抗震性能,设计一种新型黏滞-屈服型组合耗能支撑。通过ANSYS/LS-DYNA显式动力学仿真平台对钢框架与支撑的组合结构进行地震动力学仿真。结果表明,钢结构中安装黏滞-屈服型分级耗能支撑可以有效减小结构振动反应,降低结构冲击损伤。
The development of building industrialization has promoted the development of steel structures and fabricated components, of which the buckling-resistant energy-dissipation brace is widely used due to its good seismic performance. In order to achieve better industrial production and site assembly, and improve its seismic performance, design a new type of viscous - yield combination of energy-saving support. The seismic dynamic simulation of the combined structure of steel frame and brace is carried out by ANSYS / LS-DYNA explicit dynamics simulation platform. The results show that the installation of viscous-yielding energy-dissipating brace in steel structure can effectively reduce the structural vibration response and reduce the structural impact damage.
