Southern Pine (SP) is one of the fastest growing softwood species in the Southern Forest of United States. With its high strength to weight ratio, SP becomes an ideal candidate for manufacturing engineered wood products such as cross laminated timber (CLT). Two batches of CLT panels were manufactured using visually graded SP lumbers in...
The cross-laminated timber (CLT) technology is also perceived as a potential for utilization of lumber of lower grades and underused species, because the core layers perpendicular to the principle loading direction transfer loads through rolling shear, which is not correlated to the grade of lumber...
Since cross-laminated timber (CLT) panel is produced with its layer crosswise, the rolling shear stress is inevitably introduced to the cross layers if bent in out-of-plane direction. In this study, the shear strength of CLT panels was evaluated with 3-point bending test (short span) and asymmetric 4-point bending test in out-of-plane direction...
