Seismic Evaluation of Existing Basement Walls


Abstract eng:
Structural and geotechnical engineers have long relied upon the use of the popular Mononobe-Okabe (M-O) method for determining seismic lateral pressures acting on retaining walls. This limit equilibrium-based method was originally developed for rigid retaining walls with sufficient rigid body displacements to mobilize the active wedge in the backfill soil. In reality, however, certain types of retaining walls, such as basement walls, have variable degrees of flexibility and deformation at different depths. Recently, the Structural Engineers Association of British Columbia (SEABC) initiated a task force to review the problem. The authors are members of this task force committee and have carried out series of dynamic numerical analyses to study lateral earth pressures against basement walls taking into account the flexibility and potential yielding of the wall components. This paper outlines a part of the findings in this study.
