摘要
冷弯钢管混凝土异形柱具有承载能力高、耗材少及得房率高的优势,结合隅撑支撑框架体系及双侧板节点将其应用于高层结构中具有巨大的减量化潜力;面对随机性的地震动,科学设置双重可控防线是积极的应对策略,建立的串并联能量模型厘清了双重抗震结构体系与双重抗震防线的概念区别,为构建双重抗震防线提供了依据.
Due to the shortage of land supply and rapid increase in population,the construction of tall buildings in cities has been expanding dramatically in the twenty-first century that improves people＇s ways of living.However,tall buildings involve problems such as huge energy cost of construction and the lack of aseismic ability.To avoid such shortcomings,with the good loading capacity,economical material cost and relatively small cross-section size,concrete filled cold-form steel tube shaped columns are adopted as an ideal structure component for high-rise buildings.Furthermore,the scientific double aseismic design of concrete filled cold-form steel tube shaped columns could develop adequate aseismic ability of the overall structure.In this proposed research,the series-parallel energy model clarifies the concepts of double aseismic designed structure and double aseismic defense;so as to provide guidelines for development of aseismic defense.
