Please help with the modeling of a box girder. Attached is the image.
I have modeled the box considered as beam elements with width 1.5m and depth as thickness. The overhanging portion of W10x49 is modeled as dummy. I have considered the sections W10x49 and W12x40 as point loads . Please suggest if this kind of modeling is correct and how to model the gusset plate/WT6x20 bracings between them.
