CONCRETE MASONRY GRAVITY RETAINING WALLS - NCMA
WebThe retaining walls in this booklet were designed using the conventional cavity-type walls. This system appears to be the most generally used and most convenient to the designer and the builder. Reinforced Brick Masonry (RBM) has proved itself to be one of the most efficient engineering WebThe Seismic Design Category is Category D. Reinforced masonry design requires that a grout/reinforcement spacing be assumed. The grout spacing affects the wall weight, which in turn affects the seismic load. Assume a grout spacing of 48 in. o.c. Check Load Combination G (0.6D + 0.7E). fischerscope hm2000xyp
