STUDY ON A METHOD FOR ESTIMATING THE OUT-OF-PLANE BENDING PERFORMANCE OF CLT USING MONTE CARLO SIMULATION

Currently, research and development are underway to realize CLT (Cross Laminated Timber) composed of laminae with varying thicknesses. In this paper, strength and probabilistic models focusing on the bending performance of CLT were examined. First, the CLT was tested in bending to identify the point at which the initial load drop occurred. Next, the correlation coefficients for the Young's modulus, bending strength, and tensile strength of the laminae were determined through testing. Finally, Monte Carlo simulations were employed to create virtual CLT, estimating this initial load drop point. Based on these results, the validity of the calculation method is reported.
