【摘要】 普通工字形钢梁由于腹板厚度较薄发生局部失稳,使腹板的稳定承载力降低。为了解决这个问题,国内外研究人员提出了一种改进形式:波纹腹板钢梁。理论研究与工程实践证明了波纹腹板钢梁有着明显的经济效益。结合国内外研究成果,介绍和分析了波纹腹板钢梁的受力性能,包括受剪性能和受弯性能,并提出了相关的设计建议。更多还原

【Abstract】 The local buckling occured in the web plate of I-section steel beam may reduce the web’s buckling strength.In order to solve this problem,a new structure form,i.e.the corrugated web steel beam,is introduced.Combined with the achievements at home and aboard,the behaviors of the corrugated web steel beam are introduced and analyzed,including the shear buckling and bending strength,and the design recommedations for the corrugated web steel beam are put forward.更多还原
