摘要
运用刚度解析法推导了截面平均刚度公式,然后用虚功原理进行了跨中挠度计算,理论计算值与试验值吻合较好,指出该方法是计算FRP片材加固钢筋混凝土梁挠度变形的有效方法。
The formulas of section average rigidity is derived by means of rigidity analytical method, then computing the deflection of middle section with principle of virtual energy. The theory is fit well with experimental data, It is the effective way to compute the deflection of reinforced concrete beams strengthened with FRP laminates.
