I've sent out a project that is a load bearing CMU structure that has a basic bar joist supported floor and roof system and two columns in a location where masonry wasn't practical. Every wall is dimensioned to the face (inside and out), every building corner is dimensioned, every wall thickness...
I've been asked to check some connections for platforms being attached to a vessel. Connections are small brackets welded to a reinforcing pad on the vessel wall, platform arms are then bolted to the bracket. Seems straight forward enough but I have been given a design temperature of 500 degrees...
We have a project in a rural jurisdiction that has BOCA 1999 as its adopted code. BOCA 1999, of course, references much older versions of ASCE7 and AISC etc. The debate is this: Do we use BOCA99 and its assorted references for design or do we lobby to use newer codes. The project is in a high...
KootK: Thanks for the link. 3/4" cover minimum. We've spec'd this type of slab hundreds of times without trouble. I wonder if vibration would prevent plastic settlement? The mix designs were fine, perhaps they added a boat-load of water.
CEL is right. If you need them in the center tell them that is where they need to be for the wall to perform. I'd suggest bar positioners but they probably won't like either. Also look at the contract documents...surely they show the bars centered (if that was the intent) and that would give you...
Hey folks. Has anyone seen this before? Any idea of potential causes?
2nd floor slab, 2.5" NW concrete topping over 9/16" deck over bar joists at 24" max.
Exhibits through much of the slab (to lesser extent in some areas).
Photos show the mesh chaired, tied and in the proper location...of course...
Thanks guys. I appreciate the input. I think I will move to a Deck Bearing (DB) or Bottom of Metal Deck (BMD) {I like that JAE} format for most all our projects. There will most likely be instances where Top of Beam may be appropriate.
KootK: {Item 3} Interestingly, what sparked my question was...
My firm has used "Top of Steel" elevations noted along side the beam designation for years. Once the project goes out I try to ask the detailers and the contractor about our drawings and what we could do better. I have heard from detailers that "Deck Bearing" elevations would be helpful...
I've been doing buildings and industrial work for 16 yrs. Working with a good architect that respects your input is very rewarding...working with all the other architects is like self-inserting a bamboo catheter.
Industrial work can be pretty cool but only as good as the management of the...
