I have a background in designing PEB's and mini storage light gauge steel structures.
In my experience I have used either diagonal rods or diagonal flat strap bracing for my flexible diaphragms when using steel roof decking that is NOT shear rated: typical standing seam roof.
I'm reviewing...
I'm performing a plan review.
Example: 8" slab w/#3 bars @ 18" oc ea way & #4 dowels (from CMU wall) @ 24" oc. (obviously different spacing)
Does this fly?
I've typically always required/designed my slab steel and dowels to the same spacing for lapping together.
I've always had the...
IBC 2006 section 2305.2.3 gives ratios for maximum diaphragm dimensions for wooden structures.
Is there a maximum diaphragm dimension for a roof diaphragm with VERCO steel deck attached to reinforced concrete shear walls?
Thanks

I have an issue regarding anchor bolt diameters. AISC table J3.3 states for 1/2" dia. holes: std-9/16", oversize-5/8" and long slot- 9/16"x1 1/4" respectively.
I have a bearing plate on a pedestrian bridge that the fixed end has 3/4" dia...
If a modular building (trailer) is on 3 ft piers/jacks, should the base shear (at floor level) be multiplied by the pier height for an applied moment to be restrained by seismic holdowns?
I've been reviewing calculations from multiple engineers/companies and they are not accounting for the pier...
Modular Buildings supported by piers are not specifically called out in the IBC 2006 and ASCE 7-05. In southern California, San Diego, San Bernardino and Riverside counties all require Earthquake Restraint Bracing System (ERBS). I work on DOD base and have an issue with a contractor installing...
I'm doing a remodel on an existing structure. It has a 14" x 21" concrete beam spanning 18'. The building was built in the early 1950's. I know that was when working stress design (WSD) was being used. I don't have as built drawings, so I'm trying to figure out the minimum area of steel based on...
