WebIBC Section 2106.1 requires all masonry walls, regardless of SDC, not designed as part of the seismic force-resisting system (partition and nonloadbearing walls, eg.) to be structurally isolated, so that in-plane loads are not inadvertently imparted to them. The MSJC, conversely, requires isolation of such elements only for SDC C and higher. Webinvestigations have been carried out to study the behaviour of retaining walls under both static and seismic conditions. A design approach based on the concept of limited …
