摘要:减隔震技术是当前抗震研究的热点,其中,软钢阻尼器是较多应用于高层建筑的减震技术之一。本文利用NosaCAD软件,对某应用软钢阻尼器进行设计的高层建筑在9度罕遇地震下进行了非线性时程分析。通过分析结构的位移响应、损伤发展以及阻尼器的滞回曲线等性能指标,验证了软钢阻尼器对于高烈度地震区高层建筑减震的作用。

Seismic analysis of frame-core wall structure using hysteretic dampers in high-intensity earthquake region
Abstract:Seismic mitigation and isolation technique has become the focus of research nowadays, in which the hysteretic dampers are always applied in the design of high-rise buildings. In this paper, a high-rise model is built using the NosaCAD software to conduct the nonlinear time history analysis under 9-degree rare earthquake. According to the story drift, the damage evolution of core tubes and the hysteretic curves of dampers, etc, hysteretic dampers are proved to be effective in high-intensity earthquake region.
Keywords: Plastic limit analysis of structures Seismic energy dissipation of structure Nonlinear time history analysis Hysteretic dampers High-rise building
