Glulam consists of laminaes and each laminae influences glulam’s strength. Transformed cross section (TCS) method is a well known method to calculate the modulus of elasticity (E) and modulus of rupture (SR) of glulam. However, the TCS does not follow the principles due to its assumption that the material properties depend on its shape and size. Therefore, a new calculation method is required. This paper discusses the formulation of a new method to determine E and SR of glulam. It was found that E and SR calculated by the TCS and new methods are the same. The new method confirms the independencies of E and SR which could not be fulfilled by the TCS one. Therefore, the TCS method could be replaced by the new method.
