本发明涉及结构工程技术领域,具体而言,涉及一种可主次受力的钢板耗能复合型组合柱及安装方法The invention relates to the technical field of structural engineering, in particular to a steel plate energy-dissipating composite composite column capable of primary and secondary stress and its installation method

背景技术Background technique

为了抵御地震灾害,提高建筑结构的抗震能力是主要策略之一,传统的抗震设计主要是依靠结构本身的抗震性能来抵御地震作用,这种抗震方式缺乏自我调节能力,很可能不满足安全性的需要,另外结构构件尺寸过大不但使结构布置和施工不灵活,而且使经济投入过大。在高耸、大跨建筑物中柱子承受很高的轴力,而建筑物承重柱的设计是保证建筑物在大震下是否会正常工作的关键,当遇到较大荷载时,一根柱的承载能力远达不到受力要求,而当柱的截面较大时又会浪费建筑空间。In order to resist earthquake disasters, improving the seismic capacity of building structures is one of the main strategies. The traditional seismic design mainly relies on the seismic performance of the structure itself to resist the earthquake. This seismic method lacks self-regulation ability and may not meet the safety requirements. In addition, the excessive size of structural components not only makes the structural layout and construction inflexible, but also makes the economic investment too large. In tall and long-span buildings, the columns bear high axial force, and the design of the load-bearing columns of the building is the key to ensure whether the building can work normally under a large earthquake. When encountering a large load, the The load-bearing capacity is far below the force requirements, and when the cross-section of the column is large, the building space will be wasted.

As shown in Fig. 6(a) and Fig. 6(b), whether it is A-type square steel pipe or B-type square steel pipe, they can all be spliced in the form of composite components.

例如,图6(a)中,方钢管由四块方钢管组合构件依次拼接而成,每块方钢管组合构件的形状均为“L型”结构。为避免妨碍到中轴线上的其他螺栓的固定,方钢管组合构件之间拼接位置不在方管的中轴线上,而是略偏向一侧。For example, in Figure 6(a), the square steel pipe is spliced sequentially by four square steel pipe composite members, and each square steel pipe composite member has an "L-shaped" structure. In order to avoid hindering the fixing of other bolts on the central axis, the splicing position between the square steel pipe composite members is not on the central axis of the square pipe, but slightly to one side.

例如,图6(b)中,方钢管由两块方钢管组合构件依次拼接而成,每块方钢管组合构件的形状均为“门型”结构。为避免妨碍到中轴线上的其他螺栓的固定,方钢管组合构件之间拼接位置不在方管的中轴线上,而是略偏向一侧。For example, in Figure 6(b), the square steel pipe is spliced sequentially by two square steel pipe composite members, and the shape of each square steel pipe composite member is a "door-shaped" structure.
