【Abstract】 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.更多还原
