Analysis of the results of bending bearing of damaged old timber beams repaired and strengthened with CFRP

摘要

Combined with wooden beam deflection limit is reached when the load is often less than the destruction of the limit load of engineering actual situation, based on the cross section of equivalent substitution principle, set up a wooden beam CFRP reinforcement design calculation formula of calculation results, the wooden beam reinforcement and reconstruction for the future of different load cases, the design of the CFRP amount needed.
