Concrete Moment Frames
1
CONCRETE MOMENT FRAME Not very common around here. A parking garage often has 18’ stalls, and a 24’ drive aisle. This is 2*18+24=60 feet spans. That’s huge. In the other direction, you are likely to have columns every 20 feet. What is often done is that you would have a moment frame in the 20’ direction with all of those columns, and shear walls somewhere in the 60’ direction. This is called a Cunningham system, since the name of the forms for the beams are Cunningham beams. http://www.efcoforms.com/products/parking-garage/cunningham/
