I have been given a project by a local modular home company. They have been using 9.25" LVL for the intermediate floor support.
Basically, the floor is built in two sections (left side and right side). The rimrail that is supported by the exterior concrete wall is constructed with 2"x10". The rimrail where the two floor sections come in contact is constructed with a 9.25" LVL. Once the floors are in place the LVL becomes the beam supporting the floor sections down the middle of the floor. This now 2 ply LVL beam will be supported by support columns.
Most homes are 48' or less. The maximum length the LVL is delivered is 48'.
I've been asked to design a splice detail so that the LVL will continue to act as a continuous beam but be able to work on homes with floors longer than 48'. Up to now they have been splicing the LVL over support columns but they would like to have more flexibilty. They would like a splicing detail so the splice can be located anywhere within a span.
The main problem is that most homes are only a few feet longer than 48' so the splice would be located within the first or last span of the continuous beam. Anyway, I want to locate the splice within the span at the point where the moment is zero so the connection would be shear only but would require the LVL to be cut to length, this is something they want to avoid.
Anyway, do any of you see a problem with locating the splice at the point the moment is zero (approx. at the quarter span) and design a splice using shear only? The splice material will be LVL as well.
Thanks for your help and hope you understand my request.
