SRAP Pre-stressed Reinforcing Techniques for Concrete Structures

摘要

A large number of Concrete Structures need be reinforced in china. So as new rehabilitation and reinforcing techniques, the SRAP approaches were introduced in this paper, and the SR strengthens materials and AP modified resin mortars were combined with pre-stressed method in SRAP approaches. First, nowadays structure distress characteristics were presented and lots of reinforcing techniques were compared and analyzed in this paper. Based on the SRAP advantages such as the concrete crack rehabilitation and its used material innocuity and so on, the analysis results show that the SRAP are feasible and reasonable to guide the design and operation of structure rehabilitation and reinforcement, The SRAP construction measures and expected reinforcing effects were given out in this paper. The results shows that SRAP approaches with numerical simulation is feasible to guide structure rehabilitation and reinforcement, and the proposed SRAP engineering measures are effective for preventing structure local fracturing and satisfaction of rehabilitation and reinforcement targets.
