I am curious if any of you know a simplified method for estimating the lateral deflection of a cirved steel I-girder. I will eventually be doing fe, but I need to know a rough number for preliminaries.
The cross-section in the end span contains straight and curved sections, based on a "ramp" entering the span at the abut. This means that there is extra incentive to have all webs plumb at steel erection/diaphragm fit up time.
An estimate of lateral deflections (+/- rotation) will help me to know if I need shoring to make fit up in the field with diaphragms detailed to plumb webs.
