PSL 2.0E (representative) - Design Values

PSL 2.0E (representative) is a engineered wood (lvl / psl / i-joist) grade with reference design values to Representative - see manufacturer ICC-ES report. Its reference bending value Fb is 2,900 psi, compression parallel Fc is 2,900 psi, and modulus of elasticity E is 2,000,000 psi (NDS). Values are shown before adjustment factors; apply the relevant NDS C-factors or EC5 k_mod and γ_M for your load case.
