Hi guys, just wanna ask regarding a hypothetical question. lets say you have single frame with columns 30 meters apart. It is preferable to use pre-stressing on the beam for a better performance against gravity loads (unless a very deep beam is allowable, which in most cases is not). If a lateral load is to be resisted by this frame (from Earthquake, wind, or even notional load) how will you approach this?
There two approaches I could think of. One is to allow the beam to resist moment at the beam column joint, hence moment frame action. Another would be to release the beam end moments and assign a fixed base on the column, thus the lateral load will be resisted by the column (behaving like a cantilever, against lateral loads).
Not really sure which of the two is the "conventional" way to approach this. Or is there another way of addressing this?
