Lateral Torsional Buckling (2024)
Report
Plowas, W. (2024). Lateral Torsional Buckling. Timber Development UK

Lateral torsional instability occurs when a beam’s compression face is not fully restrained against lateral movement and its relative slenderness is high. The beam may fail by deflecting sideways and twisting about its longitudinal axis; this failure... Read More about Lateral Torsional Buckling.

Report
Plowas, W. (2024). Cross Laminated Timber. Timber Development UK

Cross Laminated Timber, also known as CLT or X-lam, is an engineered timber product with a minimum of three cross-bonded layers. At least one layer is orthogonally oriented to the two adjacent layers of timber boards

Designing with Cross Laminated Timber (CLT) (2024)
Report
Plowas, W. (2024). Designing with Cross Laminated Timber (CLT). Timber Development UK

The development of CLT brought new possibilities for timber in construction. Instead of framing smaller timber sections to form load-bearing structural systems, timber products using CLT can form walls and roofs of structures in large surface panels....
