基于能量平衡的连体结构性能设计方法
Performance Design Method for Energy-Balanced Connected Structures
摘要
Abstract
This paper addresses the issue of torsional damage and complex design of eccentric integral structures during earthquakes.Using a mixed isolation eccentric integral structure with viscous dampers as the research object,a performance-based design method based on energy balance is proposed.This method establishes the"energy-displacement"relationship of various modal levels of the structure through modal pushover analysis,determines the seismic energy input according to the response spectrum in the code,and predicts the inter-story drift angle response of the structure,subsequently reverse designing the parameters of the viscous dampers to meet the displacement control goals.The results show that this method can effectively predict the structural response,with prediction errors within engineering acceptable ranges,and the prediction accuracy of the mixed isolation system is superior to that of the pure isolation system.Structures designed using this method can satisfy performance objectives under various levels of seismic events.The mixed isolation strategy is particularly effective for eccentric integral structures,effectively suppressing torsion and controlling the displacement of the isolation layer.关键词
