All code provisions are listed, where applicable, on the charts for quick
reference.
•
Analysis assume rigid footing condition, resulting in a uniform soil
pressure for concentric load, and a triangular or trapezoidal soil
pressure for eccentric loading (combined axial and bending)
•
Establish preliminary size under service loads, and proportion
rectangular footing dimensions, if required, around a rectangular
column.
•
Calculate in one single equation one -way shear, two-way shear, and
design moment, under factored loads, respectively.
•
Deal separately with two eccentricity conditions, while e<L/6 flexural
equations are used, and for e>L/6 equilibrium equations are used.
•
Drive the nominal shear strength of the concrete for bo th beam shear
(one way) and punching shear (two way, or slab shear). Alternatively,
provide reference to the code provisions where shear reinforcement
may be used in case of factored shear force exceeded nominal
concrete shear strength with restricted foot ing depth.
•
Calculate required flexural reinforcement ratio and compared with the
minimum and maximum permitted by code, and provide required
tensile reinforcement, and calculate rebar development length.
•
Address axial force transfer at the column base (f or compression only),
and fully detailing the dowels design and development length required
into footing and column.
•
Include sketches illustrating the subject under investigation.
