horizontal forces on base
horizontal forces on base
(OP)
I'm trying to calculate horizontal force on a portal frame base.
Following the procedure in EC3 manual for design of steelwork and coming up with 1.37 kn. Is this too small a figure for a frame of 18 metre span,6 metre eaves height? I compared it to similar sized frame calculations done by other engineers. I have the remainder of calculations completed except for this!
Thanks

2) BA's method isn't how i remember the unit load method ...
a) solve with one roller support (statically determinate). calc deflection at the roller, D.
b) apply 1 lbs, horizontal, at the roller, solve. calc deflection of roller, d.
c) horizontal reaction for roller location is D/d lbs (in the opposite direction to the unit load).
d) solve for the rest of the frame reactions.

1.37 kN is oddly precise because that is the value the OP found when he analyzed the frame for a load which he did not stipulate.
The unit load method is one of many which could be used and you offered an excellent description of it.
