摘要
在不考虑钢板与所加固钢筋混凝土梁之间存在相对滑移的前提下 ,通过有限元分析方法。对粘钢前后梁的非线性性能进行了数值模拟分析。其中包括对梁的极限承载力、裂缝的对比。模拟结果表明粘钢加固能够有效地抑制裂缝构件中的开展 ,而利用ANSYS软件可以很好地模拟粘钢前后梁的开裂等非线性现象。
Taking no account of the relative slippage between the steel plate and RC beam and making use of finite element analysis, in this paper, the nonlinear performance of RC beam with and without bonding steel plate were compared. The comparison includes ultimate strength and crack. The results of finite element analysis were compared with the theoretical results. The results show that the bonding steel on RC beam can hold back the cracking in the beam effectively and the software ANSYS can simulate the cracking process before and after steel plate bonding on RC beam very well.
