Abstract:
This disclosure describes the invention of an improved WRI slab-on-ground foundation design method. The improved rational design method integrates any combination of rebar, wire mesh, and post-tensioned cable reinforcements into the foundation design. According to the method, cantilever lengths are derived for at least one rectangular section of a foundation for a structure. Foundation design loads typically consist of uniformly distributed loads. The invention adds the capability to include line loads representing loads transmitted to the foundation. Foundation design quantities such as moments, shears, and deflections are calculated from uniformly distributed loads. Moments, shears, and deflections from line loads are added to these design quantities. A deflection multiplier for the foundation deflections from line loads is employed for compatibility with WRI design procedures. A cracking potential of a foundation was formulated as a function of tensile stresses.
