Should I Add Diagonal Bracing to My Structural Steel Frame Design?

[benl87]

Hi there,

I've got an assignment due today and as usual have left finishing it off until the last minute. I've completed most of it but I thought I'd try and get an opinion on something.

Homework Statement

Basically our teacher has asked us for a very simple steel frame (beam, column, footing) to resist a dead and live load. He didn't want us to bother with beam-column continuity and said we could just design the column to take an axial load (half weight of beam and imposed loads) and design the bolted connection and a reinforced concrete footing. I was wondering though because I'm out of time to ask him about it should I design equal angle bars to run diagonally across the frame to provide more stability or just leave it as beam, column and footing. I know it would be best to ask him about it but I have as I said run out of time. Thanks heaps if someone could help me out.

Homework Equations

The Attempt at a Solution

Beam selected: 700 WB 130
Column selected: 200 UC 46.2
Bolted connection: 6 x 8.8/S Bolts connected via a standard 12mm beam column plate.

Bit late now, but I dread instructors who set simple design exercises that should never be built. Yes, in practice, you should think about how stability is to be maintained, but if you just accept it as a learning exercise and never build it, you will be ok.
