Translational Response of Toe-Restrained Retaining Walls to Earthquake Ground Motions Using CorpsWallSlip (CWSlip)
This research report describes the engineering formulation and corresponding software developed for the translational response of rockfounded retaining walls buttressed at their toe by a reinforced concrete slab to earthquake ground motions. The PC software CorpsWallSlip (sometimes referred to as CWSlip) was developed to perform an analysis of the permanent sliding displacement response for each proposed retaining wall section to either a user-specified earthquake acceleration time-history via a Complete Time-History Analysis or to user-specified peak ground earthquake response values via a Simplified Sliding Block Analysis. The resulting engineering methodology and corresponding software is applicable to a variety of retaining walls that are buttressed at their toe by a structural feature (e.g., navigation walls retaining earth, spillway chute walls, spillway discharge channel walls, approach channel walls to outlet works structures, highway and railway relocation retaining walls, and floodwall channels). CorpsWallSlip is particularly applicable to L-walls and T-walls (usually referred to as cantilever retaining walls). It may also be used to predict permanent seismically induced displacements on retaining walls without a toe restraint. Companion PC software, CorpsWallRotate, was developed to perform an analysis of permanent wall rotation. Both CorpsWallSlip and CorpsWallRotate software perform engineering calculations that help the engineer in assessment of the tendency for a retaining wall to slide or to rotate during earthquake shaking. Formal consideration of the permanent seismic wall displacement in the seismic design process for Corps-type retaining structures is given in Ebeling and Morrison (1992).
