Steel Plates(1).xls



This spreadsheet calculates the allowable loading on steel floor plates in accordance with Pounder's Plate Theory for uniform loading and Roark's Formulae for center point loads( concentrated over a small circle of radius r). Encastre and Simply Supported plates are considered.

The Service Load is based on Ultimate Load/Load Factor provided that the Ultimate Load Deflection is less than or equal to the allowable service load deflection. When the Ultimate Load deflection is greater than the Service Load allowable deflection then the Service Load is adjusted to ensure that the allowable deflection is not exceeded.
It often happens that the Service Load Deflection cannot be achieved without overstressing the plate at Ultimate Load.

I tried this calc on a column base plate; case 4. Question concerning the terminology. the results gave the ultimate load and associated deflection and the serviceable load based on max allowable deflection. The ultimate load deflection was half the serviceable load deflection yet the serviceable load was 67% of the ultimate. Am I confused?
