This is a question that Tim McCormick or someone else at the City of Los Angeles Building Department may be able to help with: I am presuming the City downgraded the allowable capacity of cement plaster (stucco) shear walls shortly after the 1994 Northridge earthquake because of the poor performance of this type of shear wall during the quake. I am interested in how this decision was made. Was a formal survey taken of stucco wall damage? Were any in-depth studies done as to the failure mechanisms, such as plaster failure, or fastener pullout? Were nails stronger than staples? Were there installation problems? Lath problems? New construction, or old? All of you having experiences with stucco damage are welcomed to share, and thanks for the help. Charles Laines, S.E. Long Beach, California
