Carbon fiber plates for reinforcing wooden elements: an efficiency analysis by means of ANSYS simulation

Introduction . This paper explores the efficiency of using carbon fiber reinforced polymer plates to reinforce defective wooden structures. Aim . To assess the impact of different reinforcement solutions on the distribution of stress-strain state. Materials and methods. Numerical modeling was applied using ANSYS simulation software. Wooden beams with typical defects localized in the upper and lower areas of the cross-section were selected for modeling, which provides a comprehensive assessment of the impact of defects on structural integrity. Results . Options for reinforcement are considered, which involve the use of carbon fiber plates in combination with epoxy resin, thereby significantly reducing compressive and tensile stresses, as well as plastic deformation. Seven different constructional solutions were compared, and the results revealed the optimal schemes for load redistribution and beam deflection reduction. Particular attention was paid to nonlinear wood deformation, which enables the real operating conditions to be reproduced more accurately. Conclusions . The data obtained demonstrate the high efficiency of the proposed reinforcement solution, thus opening up prospects for further experimental research, practical application in the reconstruction of wooden structures, as well as the development of new regulatory guidelines in the field of construction technologies. In addition, the study reveals the potential of modern computer analysis methods in solving complex engineering problems related to the restoration of damaged wooden structures, thus enabling the optimization of design solutions and reduction of repair costs.
