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. The cold-formed concrete filled steel tubular special-shaped columns have the advantages of high carrying capacity, less consumables and high room availability, and have huge potential for reduction in combination with the supporting system of the brace and the double-sided slab nodes. In the face of stochastic It is a positive coping strategy to set up a double controllable line of defense in a scientific manner. The established series-parallel energy model clarifies the concept difference between the double seismic structure system and the double seismic defense line, and provides the basis for building a double seismic defense line.
