For a mono-slope, 2-span, continuous roof joist with an eave overhang at one end (7' span/15' span/3.5' overhang), what is the ASCE 7-10 Component & Cladding Effective area for the joist and the overhang? With regard to the overhang, the closest examples I've found are contradictory. The...

Yes, I'm sure. I'm lacing together two columns that are about 16" apart (clear distance between flanges) with batten plates on 3'-0" centers. The columns are fixed at the base and subject to both axial load and bending loads.

Can anyone direct me to the buckling equation for a plate loaded in shear that is simply supported on its two loaded (top & bottom) edges and free on its remaining (side) edges?

I'm designing a reinforced, C.I.P., concrete load-out tunnel under a railroad track. The tunnel runs perpendicular to the track. Its top is at grade, and the track runs across it. Support for the track rails is via steel I-beams spanning between the tunnel walls. The rails are bolted to the...

I'm designing a foundation for a wind turbine. The manufacturers specifications require me to calculate and specify the grout thickness required under the tower's base plate. Does anyone know of a reference that explains how to do this?

I need to calculate the snow load for a gable roof with a 3.5:12 pitch and 4'-0" high perimeter parapet. How do you calculate the amount and distribution of sliding snow that accumulates up against the parapet? The "Cs" factor in section 7.4 reduces the the magnitude of "Pf" to account for the...
