This sections starts by saying that is applies to all earth retaining structures assigned to Seismic Design Category D, E, or F. It then goes on to say that lateral earth pressures due to earthquake ground motions shall be determined in accordance with Section 11.8.3 for Seismic Design Categories B, C, D, E, and F.
Do only earth retaining structures in design categories D, E, or F require seismic design, or is seismic design also requried for earth retaining structures in seismic design categories B and C?
According to Section 15.1.1, it seems that all earth retaining structures require seismic design, so I interpret ASCE 7-05 to require that earth retaining structures in any seismic design category to require a seismic design.
