Simulation And Analysis Of The SRAP Technique Reinforced RC Hollow Slab Beam

With the development of the times, science and technology, continues to introduce new means of transport. As transport lifeline, the carrying capacity and traffic capacity of a bridge is very important. However, with increasing of the vehicle load and speed, overloading of vehicles re-emerging, people put forward higher requirements which combined with awareness of traffic safety and comfort. Many bridges can not meet modern traffic needs gradually. Therefore, maintenance of bridge structures reinforcement studies has aroused the concern of all countries'academician. It has become an important practical and theoretical significance of the research topic.This article describes a new type of bridge reinforcement technology SRAP technology and its relevant theories. According to the data, we use finite element analysis software ANSYS to do the simulation analysis of SRAP technology systematically. Using ANSYS non-linear module, taking into account the work process of large deformation, contact and other nonlinear factors, old and new material as a whole and the bond model, we do simulation analysis of the force, slip and other parameters of the numerical. Finally, combined with hollow beam reinforced instance, we research the differences between SRAP technology and traditional external prestressing reinforcement techniques on the effect of reinforced Concrete Hollow Slab reinforcement, which applied to the reinforcing hollow beam reinforced comparative analysis of economic effect. This paper provides a theoretical basis and practical reference for SRAP technology in the field of application of our bridge reinforcement.
