通过对2种剪力连接方式外包U型钢-混凝土组合简支梁的抗剪性能进行试验研究,表明外包U钢与混凝土组合简支梁除应考虑外包U型钢腹板的竖向受剪作用外,还应考虑T形素混凝土的受剪作用。结合试验分析,采用两种方法进行计算、分析和比较,结果证明采用型钢混凝土组合结构理论法计算的理论值与试验值吻合较好,说明这种组合梁可按照型钢混凝土组合结构设计规程有关钢与混凝土组合梁竖向抗剪的相关规定进行计算。
The shear performance of U-type steel-concrete composite simply supported beams outsourcing by two kinds of shear connections is studied. The results show that in addition to the vertical shearing effect of outsourcing U-steel and concrete composite simply supported beams, , Should also consider the shear effect of T-shaped concrete. Combined with the experimental analysis, two methods are used to calculate, analyze and compare the results. The results show that the theoretical value calculated by theoretical analysis of steel-concrete composite structure is in good agreement with the experimental data, indicating that the composite steel can be used in accordance with the design rules of steel- It is calculated with the relevant regulations of vertical shear of concrete composite beams.
