I feel my “A” from CYA is well covered in that this building is typical for the era, and the area, as well. Listed are 46 tables based on common loading conditions for floor joists, ceiling joists and rafters. The user enters the member geometry, adds loads, holes and other relevant data and then selects a product for analysis. It is simple to use, yet flexible enough to analyze a variety of common applications. Combined with a context of an area with a recorded historic snowfall level of less than 1cm and a grand total of zero hurricanes, I see no reason to even raise the issue, and certainly not to refer to a SE or PE (beyond here on this forum, thanks Darren). 2.0E GP Lam LVL Floor Beams n Spacing n Spacing B A This table shows the size (e.g. BC Calc performs engineering analysis to help our customers size beams, joists, columns, studs and tall walls for their building projects. SOLUTION: Using the correct table for the roof load with 32'-0' span carried, select either 3-1/2' x 11-1/4' or 5-1/4' x 9-1/4'. EXAMPLE:A beam with a 9'-6' span supports a 32'-0' span carried for a 20 psf roof live load. In this case of this particular roof, on seeing the slope I immediately looked for signs of wall spreading. Read the beam size or choice of beam sizes from the table. And, annoying the non-greedy professionals who get called out on the referrals.įor older buildings there’s an existence proof: if it’s been there X years, is there any evidence of a developing problem? Is it a home component that wears out? My advice is to reconsider that approach, especially in a home inspection report.Īs inspectors we risk either being ignored, or sending owners on wild goose chases of fixing things that don’t need fixing. It doesn’t matter then the structure was built, when I see a problem, a material defect, or unsafe condition I analyze it based on the current requirements.
