Summary
Failure modes of Cross Laminated Timber (CLT) plates reach by an excess of tensile stress on finger joints, shear stress on transverse layer due to rolling shear effect and by natural vibration. The Probability of Failure (POF) of CLT plates can be estimated from the probability distribution of their ruptures and stiffnesses, as well as their correlation coefficients. In this context, the aim of this paper is to estimate the load capacity of Cross Laminated Timber plates from a specific probability of failure and the experimental results of mechanical and physical properties. For this purpose, CLT plates were manufactured with wood species of Pinus taeda L., from Brazilian reforestation plantations. Four-point bending tests were conducted to investigate the failure behavior of the CLT plates. Density and moisture content were obtained from small specimens extracted from these plates. Monte Carlo simulation was carried out to predict the probabilistic loads that produce the failure of CLT plates, considering the failure occasioned by natural vibration as well. Experimental and numerical results of the failure modes were compared and the maximum loads to an acceptable probability of failure of the several CLT lengths were estimated too.
