确定钢混组合梁连接件的形式与数量,直接关系着组合梁的强度与刚度,而且关系着施工操作和材料消耗。连接件数量取决于水平剪力,连接件的形式则与技术条件有关。国外大都采用栓钉,我国目前在检钉尚未大量普及推广的前提下,大都采用45°弯起筋或短槽钢。采用45°柔性钢筋作连接件时,每个连接件所承受的剪力V_s的计算公式一般为
Determining the form and quantity of steel-concrete composite beam connectors directly relates to the strength and stiffness of composite beams, and also relates to construction operations and material consumption. The number of connectors depends on the horizontal shear force, and the form of the connectors depends on the technical conditions. Most foreign countries use studs, China is currently in the nail detection has not been widely popularized under the premise of the majority of 45 ° curved ribs or short channel steel. When a 45° flexible steel is used as a connecting piece, the calculation formula for the shear force V_s per connector is generally
