【摘要】：为研究栓钉用量对大长宽比型钢混凝土短柱抗震性能的影响,对不同栓钉用量的3个型钢混凝土短柱进行抗震性能试验研究。研究结果表明:增加栓钉的用量对型钢混凝土短柱的水平承载力影响不大,但可增加型钢与混凝土之间的摩擦耗能面积,提高构件的耗能能力;此外,不论栓钉设置与否,型钢混凝土短柱均具有良好的延性和塑性变形能力,但栓钉用量的增加会加剧构件裂缝发展,降低构件延性。因此,建议型钢混凝土短柱设计时,可适当放宽栓钉用量,间距100mm以上为宜。
[Abstract]:In order to study the effect of bolt content on seismic behavior of steel reinforced concrete short columns with large aspect ratio, The seismic behavior of three short steel reinforced concrete columns with different studs is studied. The results show that increasing the content of studs has little effect on the horizontal bearing capacity of short steel reinforced concrete columns. However, the friction energy dissipation area between steel and concrete can be increased, and the energy dissipation capacity of the members can be improved. In addition, the short steel reinforced concrete columns have good ductility and plastic deformation capability, regardless of whether the studs are installed or not. However, the increase in the amount of studs will aggravate the crack development and reduce the ductility of the members. Therefore, it is suggested that in the design of short steel reinforced concrete columns, the amount of studs should be properly relaxed and the spacing should be more than 100mm.
