The high strength steel wire mesh and polymer mortar reinforcement technology has the advantages of high strength, high temperature resistance,corrosion,resistant, etc. In this paper,we analysis the flexural properties of RC beams strengthened by it using ANSYS.To bear the same moment in the same area of the reinforcement steel strand, and then get effect of different span and different reinforcement methods (comparative beam, direct reinforced beams,and secondary load of reinforced beams) on flexural load-carrying capacity and deflection, then compare and analysis,and draws the conclusion which can provide reference for practical engineering.

In order to produce required high strength steel bars for the building industry, it is necessary to provide steel with correct compositions. Effective, controlled micro-alloying is very important in the production of high strength steel bar of consistent microstructure and hence mechanical properties and weldability. Through adopting a series of measures such as molten iron pretreatment, converter final control, argon, calcium treatment, vanadium nitride and so on, a proper way to make high strength steel bar was given. The results show that the strength of the steel bars for the building industry can be increased by micro alloying with vanadium nitride. Favorable metallurgical achievements and economical benefits were gained.
