【摘要】 通过24个相同板厚和18个不同板厚S350冷弯薄壁型钢螺钉连接试件的抗剪性能试验,考察了板件厚度、板件组合方式及螺钉直径变化对自攻螺钉抗剪承载力及其破坏模式的影响。同时,根据试验结果,对比分析了中国《冷弯薄壁型钢结构技术规范》(GB50018-2002)、欧洲规范(EC3)和美国规范AISI2007、日本规范对于计算单颗螺钉抗剪承载力的适用性。更多还原

【Abstract】 Through the experimental investigation on shear behavior of the specimens of 24 same thickness and 18 different thickness, these specimens were connected by single self-drilling screw steel screw between S350 cold-formed steel plate and steel plate. This paper made a study on the factors of the shear capacity of self-drilling screw and its failure mode, and these factors can be listed as: the thickness of base metal, the sheet metal combinations and the change of screw diameter. Meanwhile, according to the test results, the feasibility of the calculating methods of the bearing capacity in GB50018-2002, EC3 and AISI2007, Japan specification were compared and analyzed.更多还原
