Vertical stress increase problem. As shown in Figure 3.27, a square spread footing is designed to support a column. The load on the column , including the foundation weight, is 600 kN. The dimensions of the foundation are B × B = 1.2 m × 1.2 m, and the foundation embedment is Df = 0.6 […]

Vertical stress increase problem. As shown in Figure 3.27, a continuous footing is designed to support a bearing wall with load of 300 kN/m. The groundwater table is far below the ground surface. The subsoil is homogeneous silty sand with bulk unit weight of 17.5 kN/m³. The width of the wall foundation is B =

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

Bearing capacity problem with one-way eccentricity. A rectangular footing is to support a column. The load on the column, including the weight of the foundation, is Q = 1200 kN. The foundation is also subjected to an overturning moment of 150 kN/m. The foundation rests in homogeneous silty sand with c′ = 0 and ′

Bearing capacity problem with inclined load. A continuous footing is designed to support a bearing wall with a load of 300 kN∕m. The load on the wall footing is inclined with respect to the vertical direction at 15°. The groundwater table is 10 m below the ground surface. The subsoil is silty sand with effective

Bearing capacity problem. A continuous footing is designed to support a bearing wall with a load of 300 kN∕m. The groundwater table is 1.0 m below the ground surface. The subsoil is silty sand with effective cohesion of 15 kN∕m² and effective internal friction angle of 35∘. The bulk unit weight above the groundwater table

Bearing capacity problem. Figure 3.26 shows that a square shallow spread footing is designed to support a column. The load on the column, including the column weight, is 650 kN. The foundation rests in homogeneous sandy clay. Subsurface exploration and laboratory testing found that the soil’s effective cohesion is 55 kN∕㎡ and the effective friction

Mr. A. brings his daughter to participate in a study comparing treatments for childhood social phobia. The researcher is required to get one parent to sign the consent form and checks that Mom and Dad are married (they are). The researcher mentions that it is unusual for a father to bring a child for treatment—usually

Fiona has obsessive-compulsive disorder. She has many intrusive thoughts, but the most frightening is that when using a sharp knife, she loses control and stabs her son, severely injuring or perhaps even killing him. Fiona loves her son and is a good mother. She is horrified about these thoughts and does not want to act
