Hi Techno,
I've been design box culvert for runway in airport, from my experience you much collect the bigger load from aircraft, in this case, impact load from aircraft so important to consider. For earthquake load or snow load, i think depend on your case and your location. Back to your question, you can use SAP2000 because that software more complete than ETABS (usually for building design). In initial design, consider loading data using AASHTO, ACI and ASCE, for you input data in SAP2000 modeling. I agree to Mr. Djulaiman for using spring value from Bowles, but if you've soil data, you must calculate from that soil information. For SAP2000 modeling, you can combine 2D frame model and shell model for more accurate calculation. Hopefully this note help u to solve your project.
