Abstract : One of the basic problems to be solved by geotechnical engineers in regions where earthquake hazards exist is to estimate the site-specific dynamic response of a layered soil deposit under a level ground surface. This problem is commonly referred to as a site-specific response analysis or soil amplification study (although motions may be deamplified). The solution of this problem allows the geotechnical engineer to evaluate the potential for liquefaction, to conduct the first analytical phase of seismic stability evaluations for slopes and embankments, to calculate site natural periods, to assess ground motion amplification, and to provide structural engineers with various parameters, primarily response spectra, for design and safety evaluations of structures. The computer program described and provided in this report, WESHAKE, may be used to accomplish this task. WESHAKE is an adaptation of the original computer program, SHAKE, written at the University of California at Berkeley by Schnabel, Lysmer, and Seed (1972). WESHAKE was created and has been continually modified by WES to keep pace with state-of-the-art technology and provide a user-friendly interface.
