I have been asked to analyze a flat slab with drop panels for a client. The flat slab was designed in 1955 and is a typical two way slab with column strips and middle strips. The client wants to cut a hole in the slab for an elevator, as close to one of the columns as possible. This will require loosing about 1/2 of a column strip. I do not have much experience with flat slab two way construction. I want some guidance form some of the experienced engineers what I should research, study, look for, brush up on, etc. as I begin to tackle this problem. The elevator shaft can be constructed from CMU block and be load bearing so I can put the load from the cut column strip into the shaft. I assume this will help the shear problem since it will not add shear to any other area around the column. I still want to stay a reasonable distance from the column. I know I need to check bending since what was a continuous span will now have a simple support at on end. Any helpful insight would be greatly appreciated. __________________________________________________ Richard Lewis, P.E.
