［摘要］通过对空腹钢柱在竖向荷载、水平荷载作用下的构件试验，研究了空腹钢柱的承载力性能；通过对有上柱的空腹钢柱以及完全空腹钢柱在低周反复荷载作用下的构件试验，研究了空腹钢柱的滞回性能及抗震性能。试验结果表明：空腹钢柱具有较高的竖向及水平承载能力，在水平荷载作用下具有较强的抵御水平变形的能力，且其对竖向荷载的PΔ效应反应不明显。同时，构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
