Fiber Stress Values for Design of Glulam Timber Utility Structures: A Data Base

摘要

The decreased availability of large timbers for structural applications has ledto the development of engineered structural wood products such as glulam. To determine fiber stresses for glulam beams manufactured with visually graded or E-rated lumber, we developed a simple equation to calculate average glulam beam modules of rupture (MOR) as a function of the design stress in bending (Fb) for glulam combinations and several end-use factors. To verify these relationships, the following test data of glulam beams were compiled.
