RATIONALE:

The proposed amendment addresses the problem of poor performance of gypsum wallboard and Portland cement plaster as wall bracing materials in high seismic areas. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEACSC) and the Los Angeles City Joint Task Force that investigated the poor performance of these bracing materials that were observed in the 1994 Northridge earthquake.
