Analysis of the deflection of reinforced concrete simple beam reinforcement using external pre-stressing force

为分析体外预应力加固对钢筋混凝土梁挠度的影响,介绍体外预应力加固混凝土简支梁的试验过程,并采用Ansys有限元软件对试验过程进行模拟,通过试验现象和有限元模拟,对加固前、后混凝土梁的挠度进行分析比较,以此说明体外预应力加固混凝土梁可以减小挠度,有限元可以有效地模拟体外预应力加固梁荷载-挠度的相关曲线,为实际工程提供参考数据。

Analysis of external pre-stressing force on the deflection of reinforced concrete beams,brief external pre-stressing forced concrete beams of the experiment,and using Ansys finite element software to simulate the testing process,through experimental results and finite element simulation,the main pairs of reinforced concrete beam deflection before and after analysis and comparison,as an example of external pre-stressing reinforced concrete beams on the beneficial effect of reducing the deflection,the effectiveness of finite element simulation of external pre-stressing beam load-deflection relationship,in order to provide some practical engineering test reference.
