螺栓连接带约束拉杆钢板混凝土组合剪力墙是一种将钢板外置内填混凝土的组合构件,为研究此种构件的抗震性能及螺栓连接的可靠性,该试验对3片高宽比为1.5的带约束拉杆钢板混凝土组合剪力墙试件,进行了水平方向低周反复加载试验。所有试件端部钢板采用槽型钢,用八螺母全牙拉杆与腹侧钢板螺栓连接。位于试件中部的约束拉杆为无牙拉杆,用双螺母螺栓与腹侧钢板连接。
Bolt connection with restraining tie bar Steel-concrete composite shear wall is a combination of external components of steel plate filled with concrete components, in order to study the seismic performance of such components and the reliability of bolting, the test of three aspect ratio of 1.5 With restrained tie rod concrete composite shear wall specimens, carried out in the horizontal direction of the low cycle repeated loading test. All specimens at the end of the plate using grooved steel, with eight nut full teeth pull rod and the abdominal plate bolted. The restraining rod in the middle of the specimen is a toothless rod, and is connected with the abdominal plate by a double-nut bolt.
