Perforated steel plate deflection calculation
Perforated steel plate deflection calculation
(OP)
Hi all,
I'm trying to design a perforated steel plate subject to two load cases, one of which is a ud area load, the other a point load. The steel plate is to be used as infill in a balustrade at a train station.
I have found Pounder's equation which appears fine but it applies to the deflection for a solid steel plate. Has anybody ever looked into checking the deflection of a perforated steel plate or has anybody any suggestions as to how I could modify Pounder's formula to give me a satisfactory answer? (Or can anybody recommend using another formula?)
The formula only takes into account the overall thickness of the plate, as opposed to it's moment of inertia. There are a number of other variables but none relate to it's cross sectional area. Please see attachment from "Steelwork design guide to BS5950-1:2000 - Volume 1" for formula.
Any help would be greatly appreciated.

In this case, do you think the ud area loading could be reduced to take into account the perforations in the plate or would you apply the whole area loading over the reduced area of plate?

Thanks for the help.
