Rigid Spread Footings Resting on Soil Subjected to Axial Load and Biaxial Bending. II: Design Aids

High Computational Efficiency Through Generic Analytical Formulation for Linear Soil Pressure Distribution of Rigid Spread Rectangular Footings

“…Imposing x-direction eccentricity in Region E by setting e y = 0, as shown in Figure 9, equations (25) and (26) yield the well-known formulas for soil pressure distribution of single slope and limited active area (37) Figure 9: Soil pressure distribution for one-way eccentricity in segment 'ce'. the equations (15) and (16) of region C, (25) and (26) of region E, and (28) and (30) of region B, yield identical results…”

“…Imposing x-direction eccentricity in Region C by setting e y = 0, as shown in Figure 8, equations (15) and 16 (34) Figure 8: Soil pressure distribution for one-way eccentricity in segment 'kc'.…”

“…All the above involve an immense amount of intensive calculations through complex iterative processes. Several procedures were developed in the past for handling efficiently such footing-soil interaction problems, by using either analytical [2,4,5,6,7,13,14], numerical [10,11], graphical [3,15], or hybrid techniques [8,9]. Although accurate and useful, some of them are rather computationally expensive, while others are not so wide-ranging or not easily implementable in designing footings of such specific shape, yet participating in a complex structure assembly subject to various loading actions.…”
