【摘要】：為研究栓釘用量對大長寬比型鋼混凝土短柱抗震性能的影響,對不同栓釘用量的3個型鋼混凝土短柱進行抗震性能試驗研究。研究結(jié)果表明:增加栓釘?shù)挠昧繉π弯摶炷炼讨乃匠休d力影響不大,但可增加型鋼與混凝土之間的摩擦耗能面積,提高構(gòu)件的耗能能力;此外,不論栓釘設置與否,型鋼混凝土短柱均具有良好的延性和塑性變形能力,但栓釘用量的增加會加劇構(gòu)件裂縫發(fā)展,降低構(gòu)件延性。因此,建議型鋼混凝土短柱設計時,可適當放寬栓釘用量,間距100mm以上為宜。
[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.
