[摘要]通過對空腹鋼柱在豎向荷載、水平荷載作用下的構(gòu)件試驗,研究了空腹鋼柱的承載力性能;通過對有上柱的空腹鋼柱以及完全空腹鋼柱在低周反復(fù)荷載作用下的構(gòu)件試驗,研究了空腹鋼柱的滯回性能及抗震性能。試驗結(jié)果表明:空腹鋼柱具有較高的豎向及水平承載能力,在水平荷載作用下具有較強的抵御水平變形的能力,且其對豎向荷載的PΔ效應(yīng)反應(yīng)不明顯。同時,構(gòu)件具有良好的耗能性能。

Abstract:The strength performance of laced steel column was studied through the tests under vertical loads or horizontal loads. And the seismic behavior was also studied through tests of laced steel column with upper column and complete laced steel column. Test results show that the laced steel column has good bearing capacity under vertical and horizontal load, and has strong deformation under horizontal load, P-Δ effects reflect not obvious under vertical load. Meanwhile, its energy dissipation effect is obvious.
Keywords:laced column; laced steel column; bearing capacity; single layer industrial building
