The shift from the traditional British Standard (BS 5268) to represents a major evolution in engineering, moving from simple permissible stress methods to a sophisticated limit state design philosophy . The Core of the Change
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
: As established in Eurocode 0, designs must ensure both the ultimate safety (strength) and everyday serviceability (deflection and vibration) of a structure.
