Analysis on Influencing Factors of Performance of NSM-CFRP Sheets Reinforcement Ancient Building Timber Beams Based on Digital Simulation

The concealed reinforcement of CFRP sheets for bending members of timber-framed ancient buildings has unique advantages. The mechanical simulation of reinforced timber beams through finite element methods, combined with Monte Carlo models, calculates and analyses the sensitivity of the main influencing factors of reinforced beams in ancient buildings, and explores the influence of CFRP sheet length and reinforcement location on the mechanical properties of reinforced beams in bending. Through the digital simulation analysis, it helps to select a reasonable reinforcement design solution more efficiently, with a view to maximising the performance of ancient buildings and preserving valuable value information.
