二次受力对粘钢加固混凝土梁的影响
Influence on RC beam with glued steel plate of second bearing force
【摘要】 粘钢加固混凝土梁在二次受力情况下存在着粘贴上去的钢板应力和应变均滞后的情况,根据钢筋混凝土梁的作用机理,分析了二次受力对粘钢加固混凝土梁界限相对受压区高度的影响。
【Abstract】 The steel plate presents delay of stress and strain, under second bearing force in the RC beam with glued steel plate .The paper analyses influence of relative limit height of compression region on RC beam with glued steel plate of second bearing force on a basis of the mechanism of RC beam.
