摘要:

通过对9根350 mm×200 mm×2200 mm 500 MPa级钢筋混凝土偏心受压柱受力性能的试验,分析了偏心受压柱荷载-挠度曲线、荷载-钢筋应变曲线、荷载-混凝土压应变曲线以及破坏形态的特点.试验研究结果表明,500 MPa级钢筋在柱中与混凝土协同工作性能较好,其强度得到了充分发挥.在试验和理论分析的基础上,提出了500 MPa级钢筋在混凝土柱中的强度设计取值fy=450 MPa和受压承载力计算公式的建议.

Abstract:

Through the test of the stress performance of nine 9 mm×350 mm×200 mm 2200 MPa reinforced concrete eccentric compression columns, the load-deflection curve, load-rebar strain curve, load-concrete compressive strain curve and failure morphology of eccentric compression column were analyzed. The experimental results show that the 500 MPa grade steel bar has good synergy with concrete in the column, and its strength is fully exerted. On the basis of experimental and theoretical analysis, the design value of 500 MPa grade steel bar in concrete column is proposed with the design value fy=500 MPa and the calculation formula of compressive bearing capacity.
