Seismic design of abutments in zone 3

Seismic design of abutments in zone 3

(OP)
Greetings,
Seeking guidance for the design of referenced item, determining the lateral load due to the soil on abutment,
Thanks

RE: Seismic design of abutments in zone 3

Abutments when used with bridges are designed to seismic performance categories A, B, C or D with D being the highest.  

Having stated that, then you should be using AASHTO for bridge abutments and if so, you'll find the Mononabe-Okabe analysis for the soil pressure acting on your abutment.
