scope:

Purpose. This manual describes procedures for the linear-elastic time-history dynamic analysis and development of acceleration time-history dynamic analysis for seismic design and evaluation of concrete hydraulic structures (CHS). The manual also provides guidance on the formulation and performance of the linear-elastic time-history dynamic analyses and how the earthquake input time-history are developed and applied.

Applicability. This manual applies to all USACE commands having responsibility for civil works projects.
