Method & Evidence

AimTo investigate the bending and shear strength characteristics of cross-laminated timber (CLT) members for industrial applications through experimental testing and numerical simulation.
MethodExperimental and Numerical Simulation
ProcedureAn experimental program was conducted to test CLT specimens (made from Southern Yellow Pine) in bending and shear according to established standards. Load-deflection curves were recorded to observe failure modes. Concurrently, non-linear finite element analysis (FEA) was performed on similar specimens to simulate their behaviour and validate the experimental results. The data from both methods were used to derive strength parameters for CLT.
