【摘要】 在粘贴片材加固的混凝土梁的锚固端应力计算公式的基础上 ,对集中荷载和均布荷载作用下的梁进行参数分析。计算结果表明 ,最大锚固剪应力和最大剥离正应力主要和加强片厚度、弹性模量、长度以及粘胶层的厚度与弹性模量有关。更多还原

【Abstract】 Based on the formula for calculating the stress at the plate end of a RC beam strengthened by plate with arbitrary forces,the parameter analysis is presented.The results show that the maximum bonding shear stress and the peeling normal stress are influenced not only by the thickness,the elastic modulus and the length of the strengthening plate,but also by the thickness and the elastic modulus of the adhesive.更多还原
