I was doing some reading in AITC 119 Standard Specifications for Structural Glued Laminated Timbers of Hardwood Species, Section 4.1.6 … “ … modulus of elasticity, E, values herein are the average values … The modulus of elasticity of wood …
The nice thing about a stiff beam is that it won’t sag much. The not-so-nice thing is that it won’t `give’. In new construction, wood framing more or less starts from the ground up; wood members are placed on top …
Let’s look at a post, say in a shop, or a barn, acting as a vertical cantilever. This means that the base of the post is held rigid (not allowed to rotate), while a lateral (horizontal, or sideways) load is …
Shear Deflection – Prefab Wood I-Joist Example Calc (c) Jeff R. Filler, Pell City, 2022 Continuing our discussion on shear deflection of wood beams (joists, etc.), let’s look at a prefabricated wood I-joists. Basic design information for prefabricated wood I-joists …
… now for `deflection’ … So far we’ve been dodging the `deflection’ issue. `Deflection’ of a beam, rafter, girder, header … is how much the beam `bows’, or bends. For a beam or rafter supported at it’s ends, the deflection …
