The loads from the slab are distributed on the walls fairly uniformly. This is achieved by making the top-most row of the blocks below the slab into a solid portion, integral with the main slab by using U-shaped blocks, specially manufactured for this purpose. Horizontal loads such as wind loads are resisted in the usual manner by treating the slab as a diaphragm and by reinforcing the walls at regular intervals in the transverse direction. Where there is no eccentric loading, the load carrying capacity of a wall constructed using ECMU is calculated using the following formula.
P=Cmxkx(FmxAb+Kc+Fc/1.3) x Ac+FsyxAs)
Where
Cm = Capacity reduction factor of design strength of reinforced masonry
(0.45 for plain Masonry).
K = Reduction factor for slenderness and eccentricity. (0.763 for 3m
highwall)
F'm = Characteristic compressive strength of masonry specimens (11.44
Mp2 for M30 and 9.36 for M20).
Ab = Bedded area of masonry cross section (64000 Sq.mm).
Kc = Factor for grout in compression.
Fc = Characteristic compressive cylinder strength of grout.
Ac = Total area of grouting in the cross section.
Fsy = Characteristic strength of reinforcement.
Ast = Cross sectional area of main reinforcement in reinforced masonry member.
