摘要: |
为研究波纹钢板纵向接缝高强度螺栓连接承载力,考虑钢板厚度、钢板面层是否热浸镀锌等因素,对波纹钢板连接试件进行静力拉伸试验,并设计同等条件下平板连接试件试验为对照组.从试件的破坏模式、纵向接缝的滑移荷载、极限荷载、滑移位移和极限位移等方面进行分析.研究结果表明:热浸镀锌对连接试件的极限荷载基本无影响;当连接试件发生孔壁承压破坏时,波纹连接试件极限荷载比同等条件下平板连接试件高12%~20%,两者极限位移相差不大;当连接试件发生螺杆剪坏时,两者极限承载力基本相同,平板连接试件极限位移约为波纹板连接试件的1.3~1.7倍.通过规范计算结果与试验结果的对比分析,建议波纹钢板纵向接缝高强度螺栓连接的承载力偏于安全地按JGJ 99—2015计算. |

Abstract: |
To study the bearing capacity of high strength bolt connection, static tensile tests on longitudinal seam of corrugated steel plate (CSPs) specimens were carried out by considering hot-dip galvanized and non-galvanized steel plates with different thicknesses, and flat plate specimens were designed under the same condition for comparison. The failure mode, the ultimate load and slip load of the longitudinal seam, and the limit and slip displacement of the specimens were analyzed. Results reveal that hot-dip galvanizing almost did not affect the ultimate load. When bearing failure at bolt hole occurred, the ultimate load of the CSP connections was about 12% to 20% higher than that of the flat plate specimens, while there was little difference in the limit displacement between them. When bolt shearing failure occurred, the ultimate displacement of the flat plate connections was about 1.3 to 1.7 times of the CSP ones, but their ultimate bearing capacities were similar. Based on the comparison between the standard calculation result and the test result, it suggests that the design formulae of JGJ 99—2015 are safe to calculate the bearing capacity of longitudinal seam strength of CSP with high strength bolt connection. |
