摘要
采用ANSYS有限元分析软件,对预应力碳纤维加固RC梁进行受力全过程分析.在有限元分析中采用升温法模拟预应力,用单元的生死实现不卸载时梁的加固.将计算值和试验值进行比较,结果表明,ANSYS能较好地模拟出RC梁的受力过程.
The whole process force is analyzed on carbon fiber reinforcement of prestressed reinforced concrete beams using ANSYS finite element analysis software.The prestress is simulated using warming method in finite element analysis,and the beam reinforcement is realized when it is unloaded using life and death of cell.Comparing calculation value with experimental value,the results show that,ANSYS can better simulate the force of the beam.
