I am working on the design of a steel framed 4 storey office building founded on piles. I have quite significant uplift loads at the columns of the braced bays. The geotechnical engineer has provided an uplift resistance of 20% of the pile compressive resistance. With 245mm dia. steel piles...
Designing slab on grade to support significant rack loads (15000# per post) and using PCA charts to design it appears as though a plain slab is off the chart (when considering 2 adjacent racks back to back will give 2-15000# post loads only 8" apart). Using finite element analysis software...
Looking for a good reference with guidlines or design procedures on analyzing existing structural slabs to accomodate new openings?
In my case I am looking at a 5 1/2" continous one-way slab spanning about 12'-0 clear between adjacent concrete beam supports with #3 bars @ 8" o.c. T&B...

That is, with the ladder fastened directly to the first truss and not over top of the gable end wall and then fastened to the first truss inside...
