How to span 30 feet with wood.
Features. LVL is stronger and more stable with a higher strength-to-weight ratio than conventional solid sawn lumber. Multiple pieces (typically used in pairs) can be fastened together to obtain greater thicknesses, resulting in greater strength to carry/support heavier loads. E Value (Modulus of Elasticity) = 1.9E or better.
Several steel plates connect the two I-beams to each other via angle iron. The plates prevent the I-beams from twisting. Bolts that go through the knee-wall are attached to the web of the I-beam with a piece of angle iron. Notice that the washers are square scraps of steel with a hole drilled in the middle.CANADIAN SPAN BOOK 2020.
