Inverted Pendulum on Shear Walls

Inverted Pendulum on Shear Walls

Inverted Pendulum on Shear Walls

(OP)
I am working on a pedestrian bridge that is 30'-0" above grade. It is supported on three single "columns" that closely resemble concrete shear walls. They are the width of the bridge (12'-0") and +/-2'-0" thick. I think that it is an inverted pendulum structure based on the definition in ASCE 7. However, when selecting coefficients for seismic design, my options are limited to the three types of concrete moment frames. Any thoughts on what values I should be using?

RE: Inverted Pendulum on Shear Walls

It's obviously a bridge pier, and I would design them as a shear walls for the seismic and wind loading transverse to the span, ordinary if possible.

Find an AASHTO Spec for bridges. They do this all the time.

RE: Inverted Pendulum on Shear Walls

VI Costello: How did you end up designing the walls for lateral loads (design for longitudinal seismic forces and fpr tansverse seismic forces)?.
