［摘要］為研究栓釘用量對(duì)大長(zhǎng)寬比型鋼混凝土短柱抗震性能的影響，對(duì)不同栓釘用量的3個(gè)型鋼混凝土短柱進(jìn)行抗震性能試驗(yàn)研究。研究結(jié)果表明：增加栓釘?shù)挠昧繉?duì)型鋼混凝土短柱的水平承載力影響不大，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(shè)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(huì)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(shè)計(jì)時(shí)，可適當(dāng)放寬栓釘用量，間距100mm以上為宜。

Abstract:In order to study the stud amount impact on the seismic performance of steel-reinforced concrete short column(SRC short columns) with large length-width ratio, seismic performance experiments on three SRC short columns with different stud amounts were carried out. The results show that stud amount has little impact on the horizontal bearing capacity of SRC short columns，but can increase the friction contact area to enhance its energy-dissipating capacity. With or without studs, all the SRC short columns have good ductility and plastic deformation capacity, but the increase of studs can accelerate column crack development and decrease its ductility. So, it is suggested that the studs should be set in the SRC short columns in moderate amount, with 100mm distance above.

Keywords:steel-reinforced concrete short column; stud amount; seismic performance; large length-width ratio
