As noted in Fig. 7.16, the state of stress shifts from plane stress to plane strain as the ratio of length-of-bend to sheet thickness increases. Explain why. This situation….
Determine the foundation’s embedment depth, dimensions, and use these dimensions to determine the allowable bearing capacity.
Bearing capacity problem with one-way eccentricity. A continuous footing is designed to support a bearing wall with a vertical load of 340 kN∕m. In addition, the foundation is subjected to an overturning moment of 170 kN/m per unit length (meter) of the wall. The groundwater table is 15 m below the ground surface. The bulk unit weight above the groundwater table is 17.5 kN∕m³; the saturated unit weight below the groundwater table is 18.5 kN∕m³. The subsoil is silty sand with effective cohesion of 25 kN∕m² and effective internal friction angle of 35°. Use FS of at least 3.0. Determine the foundation’s embedment depth, dimensions, and use these dimensions to determine the allowable bearing capacity. The trial-and-error method may be used to obtain the dimensions.
