According GFRP Connect Methods To Test Study For The Carrying Capacity Influence Of Bending Concrete Beam

In recent years lots of buildings are getting old and management problems for new buildings construction, so many quality problems for reinforcement. Now, FRP reinforced concrete building is very popular all around word. The character of FRP is light quality and high strength, so it is very widely used in civil engineering reinforcement.This article introduces different connect methods to bending moment capacity for GFRP reinforced concrete beam. Now, many papers for fiber reinforced bending moment, but there is little paper of connect method affect bending capacity. So the research for this way make people deeply acknowledge for it. Firstly, take sum up for predecessor research. Secondly, according to materials set two tests. One is depth test for connect mortar, another is displacement test for anchor. For depth test use 10mm,20mm,30mm three different depth of mortar to study bending capacity variety of FRP reinforced concrete beam. From test result we can get, when depth of mortar is 1 0mm, effect of reinforced situation is best. Make deeply discussion for this phenomenon and draw load-displacement of middle GFRP plane and concrete beam up. Displacement test study relationship between connect method and bending capacity from another side. For this test we take up 300mm,400mm,500mm displacement, three types, after loading three test beams, we can pick up the best one and draw up every curves we need.This paper use FEM software to make simulation for test beam. Select element type, set up modeling, meshing, support and symmetry restrain, non linear computation to get up some contents that we need. At the last of this paper, we can get stress-moment curves according to different bonding method and bending capacity. Finally we can get the graph about average interface bond shear stress.
