Hi, I have a project have 4 ply 2x10 built-up beams/columns. Instead of full length nails penetration in the 4 ply from opposite sides, any chance we can nail 2 ply first and another 1 ply each face with 3" nail to make it 4 ply built up beam/column? Which part of design code I can find relevant...

Jayrod12, footprint is 14x20feet. my slab is 7" with 18" deep grade beam around.

Hi retired13, it is a shed building in rural area with concrete pad and wood frame building on it. Hi atrizzy, I have grade beams at the perimeter of building between piles. I have L dowels from the grade beam to the slab all around top. Thanks.

Hi, I am designing a "doghouse" building with structural slab on void form and supported by pile system. The building is unheated year round. I have designed the slab with bottom reinforcement and slab thickening at the perimeter of building. Do you think I need top rebar in the slab for any...

Hi, I am designing a building for heavy overhead cranes(2 x 175 T). It is a conventional steel building with double column for crane runway beams. Each bent is designed as moment frame and I have vertical bracing in runway direction at every 4-5 bays. Also I have roof horizontal bracing to tie...

It will be like "PERI RCS MP materiel platform" to move materials and formworks to high rise building.

Hi, I am designing a temporary outrigger platform for a Multi - story building. I am wondering what is safety factor I should use for the platform floor and outrigger beam design? It is lightly loaded. S.F of 2 is good enough? Any codes and standards I should refer to? I don’t think outrigger...

Hi, I am desiging a building with 2-150 Ton overhead cranes and 3 ton jib crane. Columns spaced at 6.1m, crane bridge spans at 25m, roof is 20 m height and oH crane located at 11 m height.It is my first time to design crane supporting structures for this kind of monster crane I have following...

Hi, I am designing a 10 meter free standing build up column to support signs on the column top. In my design, I checked single wide flange column worked for lateral torsional buckling strength. I added second wide flange column (Side by side) for serviceability. Can any body tell me how often...

Void form will be placed under the slab. What kind of anti-crack reinforcemen I should specify? Welded wire mesh are good option?

Hi, I am new here and hope to get some suggestions on the two way slab design. I am designing a single story car dealership here in Canada (CSA codes). We decided to use structural slab for this building due to expansive soil on site. We layout concrete pile at 4.8x4.8m and slab is 150 mm thick...
