Does anyone know if the BOCA code included a 15psf partition load requirement in the early 1950s? I only have access to a 1975 BOCA code, which does have the provision. Thank you in advance.
I am designing a two story church where the design/build contractor is requesting to frame the elevator shaft out of wood to save cost. The architect thinks they can make it work per fire code. Does anyone see issues with this structurally as long as you design the wood posts at the rails...
Does anyone know how much in psf a typical high school theater curtain weighs? It looks like the velour kind in the existing theater we are remodeling.
Can anyone tell me what the seismic response coefficient of a structure means (Cs)? What does it represent? I know that V=CsxW, but does anyone know an explanation for Cs?
I am trying to determine if my large warehouse I am designing is classified as "enclosed" or "partially enclosed." There are some very large overhead doors in the project all in a row along one wall. Do you consider overhead door so be an "opening?"
This may seem like a very basic questions, but I have specified the standard detail of the diamond cut around a steel column in the concrete slab at the base for almost every steel project. In the diamond cut, we call out to put 1/2" expansion joint, and then a construction or control joint...
I'm designing a 2 level concrete parking deck - post-tensioned beams with a cast-in-place slab spanning between. It is approximately 280 feet long by 180 feet wide. Do you recommend I put an expansion joint in?
On our structural general notes page for our typical jobs, we usually put a note that says do not load concrete members before 14 days and before their specified 28 day strength is obtained. I have a contractor asking if he can load it before the 14 days. Is there an ACI document that I can...
In ASCE 7-05 section 12.4.3, it talkes about including the seismic overstrength factor where conditions require it. When is that factor specifically required, and when do you use the normal seismic equations shown in section 12.4.2?
What are your thoughts about tying a new building foundation wall to an existing foundation wall if the new building's superstructure is designed so it could stand alone if the existing building were to fall down? Do you recommend doweling or not? Does doweling help settlement issues?
For brick veneer, do you usually limit your horizontal deflection to l/600 for your backing material or can you limit it to the standard l/300 for drift? I have a situation where I am using wood studs as backing, and it is getting to be difficult/expensive to limit it to l/600. Any thoughts?
Has anyone here framed an elevator shaft with wood studs before? (It is gravity supported by the foundation) As long as there is no fire code issue does anyone see any issues with it?
I am currently designing a steel framed building with precast wall panels as the exterior facade (non structural). There are quite a few windows in the building and some of the precast panels need to be hung from the steel perimeter beams. It's approximately 800 plf of load on each beam, and...
How is the wall framing usually done around stairs with an intermediate landing? Do they balloon frame up to the height of the floor or do they put another ridge beam at the landing level? I need to use this wall as a shear wall too.
I'm designing a welded square HSS truss pipe support that is approximately 450 feet long with HSS column supports at approximately 80 feet on center. The client has insisted on using tubes because they do not want birds nesting in or on the structure. However, the truss is outside and it will...
In a wood framed building, do you have to provide hold downs continuous all the way down to the foundation at each shear wall end, or do you assume the tension force is taken out at each floor level? I have a situation where the portion of the wall resisting shear at each floor changes location...
I have a situation where there is a lintel that forms a vertical peak, but also protrudes horizontally at about a 15 degree angle. It's about a 8 foot opening with about 3 feet of brick above. Below is my attempt at a picture of it.
