Influence of Composition of Layer Layout on Bending and Compression Strength Performance of Larix Cross-Laminated Timber (CLT)

In this study, bending and compression strength tests were performed to investigate effect of composition layer layout Larix cross-laminated timber (CLT) on mechanical properties. The CLT consists five laminae, specimens classified into four types according grade layer. layer’s composited as follows 1) cross-laminating layers in major minor direction (Type A), 2) external internal applied B). E12 E16 used grades lamina for Type A B KS F 3020. results the test using same composition, modulus elasticity (MOE) was higher than A. case prediction MOE CLT, experimental 1.00 1.09 times Shear analogy method 1.14 1.25 Gamma method. Therefore, it is recommended predict by shear Compression accordance with measured be 2% 9% B, respectively. failure mode A, progress generated under load confirmed transfer from rolling or bonding line due middle direction.
