Summary
Compressive strength of cross-laminated timber (CLT) is one of the important mechanical properties which should be considered in the design of mid-rise CLT building because it work to resist a heavy vertical bearing load from the upper level. The CLT panel can be manufactured in various combinations of the grade and dimension of lamina. Therefore, an experimental approach to evaluating the strength of CLT would be expensive and time-demanding. In this paper, lamina-property based models for predicting the compressive strength of CLT panel was studied. Monte Carlo simulation was applied for the model prediction. A set of experimental compression test on CLT panel (short column) was conducted to validate this model. Using this model, the influence of the panel’s width on the global CLT compressive strength was investigated. It reveals that the CLT compressive strength increases with the increase in width of the panel (or increase of number of lamina). It can be thought that there is repetitive member effect for the CLT panel wall, which was explained by the decrease of the variation in strength in case of the model simulation. This dependency of the number of lamina needs to be considered when reference design value was determined and very narrow CLT column (Wall) will be designed.
