I have design capacity tables from the ASD/LRFD Manual for Engineered Wood Construction and it gives ASB Bending Member Capacities for 6in nominal thickness members but it only give 6x6 or bigger. I am looking for the capacity of a 4x6 wood column. Anyone know where I can find this info? Thanks.
I am trying to figure out a beam size. The beam will be 7.75 feet long and supported on both ends by a wood column. Which method below is the correct way to size the beam?
Method 1
W= Roof weight (snow+dead=65 psf) + Floor weight (40LL+ 10 DL)
W = 65 psf x 7.75' + 50 psf x 7.75'
W = 891.25...
My snow load is 55 psf. The building is 16' x 24' and the rafters are going to run parallel to the 24' length. Is below the correct way to size my rafters (spaced 24" o.c.)?
W= 55 psf (24"/12) = 110 lb/ft
M = wl^2/8 = (110 lb/ft x (12^2))/8 = 1980 lb-ft = 23,760 lb-in.
From Table M4.5-3a ASD...
I am looking at a ASD Bending Member Capacity table for Structural Lumber and I see there is a M' column and a Cr M' (Repetitive) Column. If I have floor joists or rafters spaced 16" or 24" apart and there are at least 3 of them I can use the Cr M' (Repetitive) column correct? Thanks.
I used hydrocad about 3 or 4 years ago but I can't remember a whole lot about it. I have a site where I need to size a detention basin to store the 25 year post developed discharge and let it out at the 10 year pre developed rate.
I have entered my area and time of concentration values in my...

I am starting a sole proprietorship engineering business in NY. Do I need to obtain a certificate of incorporation and then a certificate of authorization? I have checked the website and it looks like I do but I am not sure if this applies to sole proprietorships. Thanks.
A homeowner wants to install an addition on the side of his house and he said he would like to bolt a double 2x10 beam to his existing stone foundation. The new floor joists will either sit on top of the beam or on joist hangers fastened on the beam.
According to my calcs the load on the beam...
Does anyone have a good website or reference for looking up wall and roof assembly weights? For example, how much does a 2x4 wood stud wall assembly with 1/2 gypsum weigh? Thank you.
Anyone know where I can get a copy of the 9th edition ASD Steel Construction Manual. It doesn't have to be an acutal book, a download would be fine. Thanks.
When I do a deep hole test I need to determine what type of soil(s) are present. Does anyone know a website that shows/describes the different types of soils (silt, sand, clay, gravel, etc). Thanks.
