波形钢腹板内衬超高性能混凝土组合梁抗剪性能试验研究OA
Experimental study on shear performance of corrugated steel web composite girder lined with ultra-high performance concrete
为研究波形钢腹板内衬超高性能混凝土组合梁的抗剪性能,考虑钢板厚度、波纹长度和内衬混凝土厚度设计制作7个试件,通过抗剪试验,观察试件破坏形态,获取其面内与面外的挠度,并分析各参数对试件荷载-位移曲线的影响规律.结果表明:试件破坏形式为剪切破坏,内衬混凝土出现关键剪切斜裂缝,钢板发生不同程度的鼓曲,两者共同承担剪力;增大钢板厚度可以显著提升试件的抗剪性能;试件抗剪承载力随混凝土厚度的增大而增大,但继续增大混凝土厚度,承载力增大速率反而变缓;当波纹长度…查看全部>>
In order to study the shear performance of corrugated steel webs combination girder lined with ultra-high performance concrete,seven specimens were designed and produced by considering the thickness of the steel plate,corrugation length and thickness of the inner lining concrete.Through shear tests,the damage form of the specimens was observed,the deflections in and out of the face were obtained,and the influence of each parameter on the specimen load-displa…查看全部>>
