I am really hoping to pass the se exam this april. I need to focus on the lateral bridge exam, specifically Section 3.10.9.4 (Calculation of Design Forces - Zones 3 & 4). I have yet to find a fully comprehensive example for this, which references the new LRFD standards. Also, does anyone know of any good seismic column and footing design examples for AASHTO LRFD?

Thanks

Seems to me modal anaysis, either singular, multimodal, or otherwise, is required in addition to the Zone 1 & 2 load calcs. Grab a bunch of tabs and refer back and forth to the several different sections it tells you to in 3.10.9.4.1. It's a pain but it's how it's set up.

I'd look around on the CalTrans website. they may have some design examples.

Try this. You'll get some leads.
