| With the development of the country, from China’s construction industry to create a new turn to the New Retrofitting parallel period. At present, at home and abroad on the building structure Retrofitting use of bonded steel plates or carbon fiber, structural adhesive anti-aging poor performance problems limited the reinforcement of structural adhesive applications development. To solve this problem, this article describes the use of anchor bolts to replace the structural adhesive to connect the steel plate and concrete, common role in reinforcement. Study the reinforcing effect of this strengthening method and to determine the anchor bolt layout and quantity is the focus of this study.Anchor steel plate reinforced concrete eccentric compression column Numerical Simulation and Analysis. First, analysis with ANSYS software to simulate the mechanical behavior of different anchor bolt layout and steel sectional area anchor bolt steel reinforcement column, the results show that the anchor bolt steel plate reinforced the column bearing capacity of the largest margin of increase was49.1%, the force improve the performance of the anchor bolt layout and number of reinforcing effect from the controlling; Then bonded Steel reinforced concrete eccentric compression column method of steel plate bonding shear stress distribution law of the anchor bolt steel reinforcement equivalent of the anchor bolt layout and simulation, to study the impact of the initial stress level of the reinforcement effect, summed up the anchor bolt steel plates to reinforce the bearing capacity of reinforced concrete eccentric compression column formula and anchor bolt layout; with an engineering example again, demonstrated the superiority of the anchor bolt steel reinforcement and finite element simulation of this article of scientific rationality. This article deals with the problem and the conclusions available theoretical preparation and practical engineering reference. |
