梁侧锚固钢板法中钢板受压屈曲特性试验研究
Experimental study on local buckling of steel plates in bolted-side plated beams
摘要
Abstract
Eight local buckling push test specimens for the steel plates in bolted‐side‐plated (BSP ) beams were fabricated and tested under concentric or eccentric loading conditions .The variation of the local buckling stress field , the ultimate buckling strength , the longitudinal deformability and the transverse buckling deformation of the bolted steel plates as the difference in bolt spacing ,plate thick‐ness ,and the arrangement of longitudinal and transverse stiffeners were investigated .Test results in‐dicate that the buckling strength increases as the increase of plate thickness and the decrease of bolt spacing ,and using smaller bolt spacing is a preferable measure to improve the buckling strength .The utilization of longitudinal stiffeners can increase the buckling strength significantly and greater section dimension shows greater performance .However ,the transverse stiffener shows no visible beneficial effect .关键词
