Planning on building (24 x 30) 3 car garage. Home office to be under garage, need to know thickness of concrete pad and car load for calculating size of 6 - 24ft beams. There will be a 7/12 roof with no floor above the garage, just below. Walls will be 10 inch block. Can anyone help with this calculation.

Composite Concrete/Steel Joists
Consists of 2-1/2 to 4 inch layer of concrete placed on a steel deck or ribbed pan that is supported by steel joists. I indicate above the W8-24 sections will work. Usually these are light guage steel trusses "C" joists spaced at no more than 24 inches . But plz provide some more info on the rib pan you plan on using and i can specify the shear stud spacing. Typically interior decks shall be of six inch wide, unpainted 18 ga. slip resistant galvannealed steel per ASTM A-924, A-60 with recessed fasteners. A six inch panel is nominal 5" flats with a maximum 1" recesses (over 1" recess is unacceptable). Panels must be brake formed and provide inside radiuses no greater than 1/8".

Concrete/Steel Deck
Metal deck made from plain or galvanized steel sheet rolled into ribbed profiles can be used to form concrete floor slabs. Steel deck can be used strictly as a form for the concrete deck slab or it can be used as part of a composite design where deck and concrete act together structurally. For house construction, 18 - 24 ga. (1.2 - 0.6 mm) sheets with 1.5 - 3" deep ribs is used. For design, either the ASCE Standard Specification for Design of Composite Slabs or the SDI Composite Deck Design Handbook should be followed.
