摘要
采用混凝土非线性应力应变关系并考虑受压钢筋的影响,推导出CFRP粘贴钢筋混凝土矩形梁截面延性系数的计算公式,讨论CFRP加固量、配筋率等因素对梁截面曲率延性的影响。
Based on the nonlinear stress strain relation of concrete, this paper calculates the ductility coefficient of the section of double reinforced concrete beams bonded with carbon fiber reinforced plastics (CFRP), and discusses CFRP amount, steel reinforced ratio effect upon beams curvature ductility coeffi dent.
