: Unlike steel, timber is a natural material with knots and grain irregularities that influence its load capacity . Engineers must account for these using specific strength classes.
: Eurocode 5 requires designers to consider how humidity and duration of load affect timber strength over time. Structural timber design to Eurocode 5
Historically, timber design relied on experience and simple safety factors. Eurocode 5 introduced a common European basis for timber design, allowing for the use of advanced like Glulam and OSB, which offer greater architectural freedom and standardized performance. Key Design Pillars : Unlike steel, timber is a natural material
