粘钢加固混凝土梁受剪性能试验研究OA北大核心CSCDCSTPCD
Experimental study on shear performance of concrete beams strengthened with steel plates
通过对11个普通钢筋混凝土(RC)梁试件及4个部分预应力混凝土(PPC)梁试件采用U形钢板箍加固的抗剪试验和数值分析,研究不同损伤程度、剪跨比、配箍率、钢板箍间距、预应力水平、钢板厚度等因素对粘钢加固混凝土梁受剪性能的影响。结果表明:采用U形钢板箍对RC梁进行抗剪加固能够有效抑制斜裂缝的开展,提高加固梁斜截面受剪承载能力,并改善梁的延性;采用相同粘钢量对PPC梁抗剪加固的效果不如RC梁明显,受剪承载力提高幅度较RC梁小;梁损伤后加固,箍筋及钢板箍…查看全部>>
An experimental study and numerical analysis on eleven reinforced concrete(RC) beams and four partially prestressed concrete(PPC) beams strengthened with U-shaped steel strips were carried out under static loading.The influences of damage degree,ratio of shear span and effective depth of section,stirrup ratio,spacing of the steel strips,level of effective prestressing,and thickness of steel strips on the shear performance of these strengthened beams were inv…查看全部>>
