I'm still trying to get info on this cabinet (voltage), but I have a project that has an existing steel column where a high voltage electrical cabinet (20' long x 8' wide x 6' tall) is to be installed on the concrete slab in the vicinity of the column. The manufacturer of the cabinet states a...
Throwing this out there to see if anyone has any other ideas or suggestions. We have a pre-engineered rigid frame metal building that has a 200' clear span, which results in some pretty high thrust forces at the base of the columns (90k). The building will be on large (11'x11') spread footings...
Hey all,
Are there major changes between the two ACI 318-05 and 02? I will be taking my SE I and II exam this fall and they require the 05 code. I have the 02 code, and they just released the 08 code. Buying the outdated 05 code at full price just for the test is not something I'm fond of...
I was asked to do a slab and footing design for a building addition that will house a 4300 gallon equalization tank. The addition is 14'x20' and the tank takes up part of the building with a footprint of 8'x12'. The architect proposed a 4" concrete pad atop the building's slab. My supervisor...
I downloaded many of the TEK manuals for assistance in a masonry CMU retaining wall. With a CMU retaining wall, you typically put the reinforcement at the back of the void. For example, a 12" CMU block would have roughly a d = 8.625". Most of the masonry examples that I have are for walls and...
Does anyone have any suggestions for masonry design? This is not something I use very often and all I currently have is the ACI masonry code. I looked on Amazon and pretty much all books had mixed reviews. The majority of my design with masonry is retaining walls, columns, and single story...
Hey all, I'm having troubles finding the minimum reinforcement required for AASHTO. I'm more familiar with ACI, and those requirements are 200/fy or 3f'c^0.5/fy. I've found in section 8.17.1.1 that minimum reinforcement should provide enough strength to develop at least 1.2Mcr. The only...
We were just hired to design a few sign structures for a new Gas Station and Truck Stop. One sign is 70' tall and the other is 30' tall. They want them to be a single mast sign. I've done sign designs in the past using masonry but none with round steel (or maybe aluminum?). The AISC manual...
I'm in the preliminary stage of a couple Sedimentation Basin designs and am looking for a few tips. Most slab on grade designs involve vehicle loading and/or column/post loads. Sedimentation basins are normally full of water and some soils at the bottom. What is the general consensus in...
