Design Acceleration for Retaining Wall 1

[EricM9]

This is my first time to design a retaining wall. Im using Retain Pro software. One of the inputs is Design Acceleration, Kh under seismic loads. Can someone give me idea how to find the correct design acceleration? The geotechnical engr only supplied the following data:
UBC 1997
Soil Factor = 0.4
Soil Type = SD

Also, is there a limit on height of retaining wall where seismic is to be considered? Example, if the height is less than 4ft then you dont need to consider seismic.

Hope you guys can help me on this.

Thanks!

EricM9,

Ask the geotech for the recommended kh. If the jurisdiction the project is located in requires design to UBC 1997, then you should probably obtain a copy.
