I'm designing a metal stud shear wall the lateral shear at the top of the wall is about 10 kips. The tension compression couple at the end studs is also about 10 kips. I want to use a gusset plate at the corner (screwed to the sill plate (track stud)) and to the vertical studs. The strap will...
I have a question regarding cap plate connections. I've had some connections where I had a simply supported beam bearing on a TS column with a cap plate. I typically check the plate for local yielding and crippling of the TS wall per AISC 13 and the cap plate bending stress. However I...
I have a situation where I'm designing a transfer beam in a concrete building. The columns are cast in place with brackets picking up precast T beams. The case is that one column near the center of teh building needs to be removed. I designed new TS columns near next to the existing columns...
I recieved a project a couple days ago to do. It's s one story wood structure about 100'x50'. It's not rectangular, but skewed about 30 degrees maybe a bit more. Anyways, I have do design for the governing load out of wind and seismic. It's in Michigan so I think wind will govern. There are...
Hi,
I have a question about lateral bracing for a beam I'm designing. It's an existing 2 story structure, built 2 years ago. The setup is repetitive. Anyway, they want to remove the 2nd story mezzanine and and 2 interior columns from the interior of the building and hang the roof from a new...
I have a situation where exterior columns of a 7 story building are flush with the property line at one side of the building. Because of this I have eccentric footings at these locations. I want to design a strap beam at these locations, but am unsure about how to go about this. The footing...
Hi,
I'm modelling the 2 cores of a 7 story building using RISA 3D. The cores are on 30" thick mat foundations connected to 3 adjacent footings. One footing is part of the mat, and the other 2 are connected to the mat by strap beams. When I run the model and plot the moment contours, the...
I'm currently working on a post-tensioned flat plate slab analysis and haven't had much PT design in the past. Does anyone know of a good book or internet resource for the design and just general info on PT slabs?
Thanks
I have a question about computer modeling. The extent to what I've used RISA, STAAD, and SAP is just modeling of an entire structure. I've always wondered though...can you design/check welds and bolted connections with these programs? How would I even do that? Or if I can do it, do I have to...
I'm working on a project with a pan joist roof. It's a 60'x40' building. I took the measurements and it's 20" form with 5" ribs 25" o.c.. The depth of the ribs is 8" with a 3" topping for a total depth of 11". I don't know the amount of reinforcement so I assumed the minimum. According to...
I'm currently designing two built up channel sections to take the load from a column. The channels will span across 3 columns, with new HSS supports at the outer 2 columns. Pretensioned thru bolts will be used to fasten the existing center column to the built up channels. Once everything is...
