Document Summary

A useful tool in analysis/design of masonry walls and columns. A solid masonry wall with maximum compressive stress = fm and maximum tensile stress = 0 (cracks at zero tensile stress) Under pure axial load, the maximum load p that can be applied is a concentric load po = fmbt. If the load is eccentric then the stress distribution changes. P o bt f = m f = m. * f = 0 when e = ek = t/6. For equilibrium, p = c and the lines of action are the same and x =3(t/2 - e) We can also plot the interaction between p and m (m = pe): e. Usually the diagram does not go to zero moment since reinforcement provides flexural capacity. If the combination of pf & mf lie inside the p-m diagram for a given wall then the design is safe (if outside then redesign)
