Quick sense check on deflection calculation

[Mech King]

Hi guys,

I just wanted a quick sense check. I have uploaded two images; one showing basic free body diagram, one showing some quick scoping calculations.

My question is, to do a simple deflection calc on the box section legs of the frame, do I just use two multiples of my second moment of area in the deflection calculation, as I have done on the second image? Since there are two ventricle legs? Ignore the value "Seis.x" in the calculation, this is just a seismic load scaling factor!

Simple problem I think, but my brain is fried from MathCad all day :/

Cheers

Sorry, all sorted now. Good nights sleep was all that was needed :)
