![]() concentrated load in the middle of a 16' span. Is your living room furniture really that stout to require something so heavy?īy comparison, the Weyerhauser book I have shows a double LVL at 7-1/4" deep being good for a maximum bending moment of 7100 ft.-lb., which converts to only a 1775 lb. with a wide-enough 1/2" cover plate welded or bolted to the bottom flange. But his depth requirement (8") is the controlling factor.Ī steel W 8 x 35 spanning 16' can support a single concentrated load (in the middle) of 15,600 lb., without a cover plate. So my question is, is there a good solution to replace the steel I-Beam with an LVL and what dimensions etc would the LVL beam need to have?Īctually, gunguy, LVL strength is related more to depth than width. ![]() To maximize overhead clearance I need to keep the beam height to 8" max (which is why I originally went with a steel beam). The advantages of thinking about going with LVL is the quicker availability and it would be easier (lighter and better to work with than steel) to install. So I got wondering if I could use an LVL beam, or perhaps a couple, installed side by side, and spiked together to optimize the strength. I am sourcing the beam through a friend of a friend, but because that person is going on vacation for a month (would be nice!), I have to delay my project. The new span of the beam will be 16' and I am (was) planning to use either a W8-35 or W6-28 (with a 1/2" cover plate to give it a bit more strength) I-Beam. At my cottage I am opening up the basement (to install a pool table) and removing a steel post in order to provide a wide open area.
