无腹筋混凝土梁的碳纤维抗剪加固试验研究

对一系列无腹筋碳纤维加固梁进行了试验研究 ,分析了影响碳纤维抗剪加固效果的因素 ,并比较了粘贴方式的不同对无腹筋梁的加固效果 .根据试验结果 ,得出无腹筋梁碳纤维加固的脆性特征比较明显 ,对于矩形梁 ,斜贴与U型贴对于极限承载力的提高基本相同 ,而斜贴碳纤维布更能有效约束加固梁的变形

Experimental Research on Concrete Beams without Stirrups Strengthened for Shearing by Using Carbon Fiber Reinforced Plastic

This paper studies the experimental research on a series of carbon fiber reinforced plastic (CFRP) reinforced concrete beams without stirrups,analyzes the factors that affect the shear reinforce effects by using carbon fiber reinforced plastic and compares the effects on differing in the plaster mode.According to the experimental results,in this paper we can see that the brittleness character of concrete beams without stirrups reinforced by CFRP is quite distinct,for rectangle beams,inclined plaster mode and U plaster mode enhaning equally the terminal load resistance capacity,but inclined plaster mode can better restrict the transfiguration of the reinforced concrete beams.
