FRP profile pipe-square steel pipe staggered arrangement double-pipe-column structure
The invention relates to an FRP profile pipe-square steel pipe staggered arrangement double-pipe column structure. The column structure comprises a square steel pipe, square steel pipe concrete, interlayer concrete and FRP profile pipes. According to the center column structure, the square FRP profiles and the square steel pipes are arranged in a staggered mode, good ductility can be provided for the structure by means of the good elastic-plastic deformation capacity of the square steel pipe core column, large section resistance moment can be provided by means of the characteristics of light weight, corrosion resistance and high tensile strength of FRP, meanwhile, the structure can be less corroded or prevented from being corroded by the humid environment, and the service life of the structure is prolonged. The durability of the column is improved. According to the staggered arrangement mode, the problem that the non-corner constraint of the internal square steel pipe core column is weak can be effectively solved, the local constraint force is improved, the overall and local stability is improved, the high bending resistance can be guaranteed under a certain material consumption by using the square section, and connection treatment of beams is facilitated.
本发明涉及一种FRP型材管‑方钢管错位布置双管柱结构，该柱结构包括方钢管、方钢管混凝土、夹层混凝土和FRP型材管。本发明中柱结构采用方形FRP型材、方钢管错位布置方式，能利用方钢管芯柱良好的弹塑性变形能力，为结构提供良好的延性，还能利用FRP轻质、耐锈蚀、抗拉强度高的特点提供较大的截面抵抗矩的同时使结构能够少受或免受潮湿环境的侵蚀，提高柱子的耐久性。本发明中错位布置形式可以有效解决内部方形钢管芯柱非角部约束较弱的问题，提高局部约束力，增加整体和局部的稳定性，且使用方形截面可在一定的材料用量下保证高的抗压弯性能，并便于梁的连接处理。
