Study on Simplified Calculation Method of Bonded Reinforcing Materials Consumption

摘要

Accurately defining the consumption of bonded reinforcing materials is most important for the efficiency of strengthening design. In order to reduce the workload of reinforcing calculation, based on the calculation theory of the front section bending bearing capacity of RC flexural members, established the relation between the relative increment of tension reinforcement of flexural members and relative increment of bending bearing capacity. Hence raising the estimating method of tension reinforcement areas for intended reinforcing beams. Finally, according to the principle of equivalent tension between strengthening materials and the needed reinforcement, put forward the estimating formula both for steel plate and CFRP in bonded reinforcing engineering. By comparing the calculation data with the experimental results, the formula can be well used for the calculation of consumption of bonded reinforcing materials. The calculation method has the important practical significance for bonded reinforcing design.
