Abstract:
Experimental study on the fundamental behavior of box shape steel reinforced concrete(SRC)beams was conducted.Seven 1∶3 scale model SRC beams were tested to failure.The experimental results indicate that the flexural strength increases with the increase of the ratio of flexural reinforcement and the thickness of flange of the shape steel;the shear strength increases with the increase in the thickness of the web of the shape steel.Concrete filled in the box shape steel can prevent the early failure of specimens due to the buckling of the box shape steel, and increase the ultimate load.Measures should be made to strengthen the connection and co-work between the shape steel and the concrete.Formulae for flexural and shear strength of the composite beams are proposed, and the calculated results are in good agreement with the experimental results.In general, the box shape SRC beam is a kind of ductile member, and it is suitable for extensive engineering application.
以7根1:3模型梁为研究对象, 试验研究箱形型钢混凝土(SRC)梁的性能.试验结果表明, 箱形SRC梁的抗弯强度随纵筋配筋率和型钢翼缘板厚度的增大而提高, 剪切强度随型钢腹板的厚度增大而提高.箱形型钢内浇注混凝土不但可避免型钢屈曲破坏而且还可提高梁的极限荷载.型钢和混凝土间的连接需要改善以加强混凝土和型钢的共同工作作用.给出了箱形SRC组合梁的抗弯承载力和抗剪承载力计算公式, 计算结果和试验结果吻合良好.箱形SRC组合梁是一种延性构件, 适用于工程实践应用.
