Has anyone detailed this? Got a bearing wall situation where the client wants to use steel studs (with parapet) at the exterior walls, but still wants exposed wood roof framing. I am envisioning using smaller bolts through the ledger into the studs for bearing, blocking for lateral transfer to...
sorry my statements were written quickly. Truss is 18' simple span, no midspan support. Max deflection is actually measuring out at 3/4". The max deflection is occurring at the open truss panel, which also is at center span of the truss, so it is deflecting over the entire length, but it does...
Great points. I just got back from the site and can confirm there is a partition wall above this location that more than likely is tied to the floor trusses at the floor above that could be imparting additional loads as you noted. These loads would apply to all the trusses in this room, and...
Got another one to bounce of you all.
Ran into a spot in an existing town home with 18" plated connection floor trusses spanning +/-24 feet. About 10 foot in, 2 of the trusses have web blockouts about 24" wide with no diagonal members, I'm guessing for mechanical, but there is nothing running...
They are not afraid of the footing size which is good. We discussed embedding into the concrete, and I though we were going to proceed this way, but they are rightfully concerned that they can't easily replace posts in that scenario. This is going into a city park, so longevity/maintenance is...
Working on a free standing trellis design where the client is wanting no visual connections of the framing over the top of the trellis posts. No knee-bracing either, so no clear way to create a moment connection at top of post to create frame action. Anyone looked into creating a moment...
Would there be some precedent to check the wall for a temporary wind exposure? IE someone doesn't realize the wall needs to be braced for a week or 2 after the fire?
Has anyone been able to get an out of plane capacity for the aluminum breakaway clips used for a fire rated shaftwall assembly? The clip is intended on holding the wall in place in case either side of a building structure burns away and leaves the clip on the protected side in place. In this...
I'm pretty sure I saw an article by Ghosh once in one of the trade magazines where he said to use table 1604.5 over ASCE 7-05 occupancy category table. I need to look closer at the 300 vs 5000 clause, I would think large retail/warehouse could exclude the 300, but have the square footage to get...
2006 IBC table 1604.5 notes "any other occupancy with an occupant load greater than 5,000" is an occupant category III. Table 1.1 in ASCE 7-05 does not have this requirement. Per section 102.4, it appears the 2006 IBC will control. Has anyone else sought clriafication for this from ASCE or...
Does the 2006 IBC or current AISC restrict the use of knee brace frames? I think I've seen comments on KBMRF's before, but did not know if they are disallowed now. Any direction to technical info for this would be appreciated.
I would like to find a reference to check a concentrated wheel load for a 3.5" LW concrete slab over 28ga form deck. Has anyone come across a reference with eqns./commentary on this subject?
