摘要
基于低周往复拟静力试验,研究了核电工程双钢板混凝土组合剪力墙钢板在低周往复荷载作用下的屈曲性能。通过对9个缩尺比为1:5的双钢板混凝土组合剪力墙试件进行试验,研究了双钢板混凝土组合剪力墙的破坏模式以及栓钉间距、竖向荷载、连接件形式和钢板厚度等参数对钢板屈曲性能的影响。试验结果表明:钢板发生屈曲的部位位于剪力墙底部,钢板发生屈曲先于试件破坏,剪力墙的设计比较好地发挥了钢板的抗拉强度,栓钉和加劲肋的设置在一定程度上可以提高钢板的屈曲荷载。
Based on the low cyclic loading test,the buckling behavior of steel plates in double steel plates and concrete-filled composite shear wall in nuclear power engineering under low cyclic loading is studied in this paper.9 specimens of SCSW with scale ratio of 1:5 were tested by low cylic loading test.The failure mode of double steel plates and concrete-filled composite shear wall in nuclear power engineering and the effects of stud spacing,vertical load,connector form and steel plate thickness on the buckling performance of steel plate were studied.The test results show that the part where the steel plate buckles is loaded at the bottom of the shear wall,the steel plates buckled before the specimen failed.The structural design of double steel plates and concrete-filled composite shear wall in nuclear power engineering gives full play to the tensile strength of steel plate.The setting of stud and stiffener can improve the buckling load of steel plate to a certain extent.
