I have the following question regarding the maximum nominal shear strength values for masonry walls. On a recent project I was evaluating the capacity of a two level parking structure with masonry shear walls using the strength design provisions in the 1994 UBC. Table 21-J (p.2-353, vol. 2) states the maximum values for the following term: V(n)/(A(e)*(f'm)^0.5) are dependent on the calculated value of M/Vd. The table continues by stating that the term A(e) is limited to the range 250in.^2 - 380in.^2. If A(e) is refering to the area of the masonry shear wall then 380in^2 is equivalent to an 8" thick by 4'-0" shear wall. This seems rather small. This limit on A(e) is puzzling to me. When I looked in the 1991 UBC code Table 24-N everything was identical except that there was no restriction on the maximum value of the term A(e). Does anybody know if the maximum value of A(e) in the 1994 UBC is correct and what the intention of that provision is ? Sincerely, Stephen Fisher, PE ...
