INTRODUCTION PROSHAKE ProShake is a powerful, user-friendly computer program for one-dimensional, equivalent linear ground response analysis. Written completely from scratch, ProShake includes numerous features to make data entry, analysis, viewing and documenting of results efficient and effective, including built-in modulus reduction and damping models, graphical display of soil profile and input motion parameters, graphical display of a wide variety of output parameters, and animation of ground response. ProShake is organized into three "managers" -
