Architect is showing a 6" CMU course at multiple locations in an 8" CMU wall so that it creates an architectural band (reveal) around the buiding perimeter.
Does anyone know where I can find out how to address this in ACI 530? Or any other document or article that can help me determine if this...
Design foundation for seismic forces or not?
The transformer is an electrical component which is, along with it's attachement, exempt from Chapter 13 if located at a site with an SDC = B.
Does that mean the foundation does not have to be designed for seismic forces?
I say yes. What is your...
My grandfather's house is settling at one end, substantially. It is located in Huntington West Virginia. It is approximately 80 years old single story and is located along the side of a street where the land was stepped to place each house. The uphill side of the house is a retaining wall, 4...
Can anyone lead me to literature that would apply to cutting an existing 10" wide by 96" deep concrete beam in half (depth) and adding external reinforcing to strengthen the beam. The initial thought is to bolt channels to each side of the beam and then cut the bottom of the beam off. The...
Existing one way slab and beam floor system. New equipment leg is to be located near center of slab instead of on an existing beam and the slab can not handle the point load. Has anyone ever installed a new concrete beam between existing concrete beams in order to support the equipment leg or...
Need help with reinforcing a cold formed steel brace. Brace is inadequate due to buckling and want to add cover plates or other cold formed sections to increase the moment of inertia. I can come up with the needed moment of inertia but don't know how to determine the length of the reinforcing...
Can anyone tell me whether the attached photo is a building constructed as concrete moment frames or concrete frames with masonry infill shear walls? Or a combination. Building was originally constructed in 1958 in Oklahoma City. Obviously it is under renovation but I believe the openings on...
Does anyone know of a device that can locate structural steel behind drywall? For example, conventional steel framed building with gwb walls to the underside of the spandrel beams, therefore can not see diagonal braces. Is there some device that can detect the braces? Or am I going to have to...
I have come across a Typical Column Base Detail for a steel column that shows the top of footing at 16" below finished floor. The slab is 4" thick and the diamond around the column is shown as 4" thick. I have always seen the diamond extend from finished floor down to top of footing and encase...
Has anyone seen CMU lintels constructed with a unit that looks like a standard block turned vertical. Do they make a lintel block that is 8" wide, 16" deep (vertical), and 8" long (parallel to wall)? Structural details call for a 16" lintel over a large window opening. There are four courses...
Anyone have any good references for designing mat foundations by hand. Not combinded footing with two columns, but mats that support equipment with 8 to 10 columns or mat foundations that support 10 to 12 pieces of equipment such as pumps, horizontal and vertical fuel tanks (10' diameter), etc...
3 leg lattice communications tower, 450 feet tall supported on (3)- 6' to 8' diameter drilled shafts. Each leg is supported on a base plate that is grouted with 4 anchor rods. The base plate is centered on the foundation. The drilled shaft appears to extend above grade approximately 12" to...
