摘要
运用有限元计算软件Ansys对CFRP加固钢结构的受力情况进行分析,分别计算了端部不锚固、一端锚固和两端全锚固的情况,对比出了不同锚固情况对于钢结构加固效果的区别.相比于端部不锚固的情况,对加固的碳纤维进行端部锚固,可以使端部碳纤维受力均匀,并且减小端部承受的剪应力,更好地起到加固钢结构的效果,并结合实际的实验情况验证了有限元计算的正确性.此方法模型是正确的,可以用于相关问题的研究.
By using the finite element software Ansys for force of CFRP reinforcement steel structure are analyzed, the ends without anchorage, end anchorage and ends anchorage are analyzed and calculated, comparing the different anchorage for the difference reinforcing effect of steel structure. Compared to the end without anchorage, the end an- chorage of CFRP can make the end of carbon fiber uniform stress, and reduce shearing stress of the end part, and make the effect of steel reinforcement better. Combined with the practical experiments to validate the finite element calculation. This model is correct, can be used for study related issues.
