2.13 The soil profile at a site is shown in Figure P2.13. The moist and saturated unit weights of the sand are 17.0 kN/m2 and 20.0 kN/m3, respectively. A soil specimen was taken from the middle of the clay layer and subjected to a consolidation test, and the following properties are reported: Natural water content of the clay = 22.5% Specific gravity of the soil grains 2.72 Preconsolidation pressure 110.0 kN/m2 Compression index = 0.52 Swelling index 0.06 a. Is the clay normally consolidated or overconsolidated? b. If a 2 m high compacted fll with a unit weight of 20.0 kN/m3 is placed on the ground, what would be the final consolida- tion settlement?

For each of the building properties listed below, identify which parameter from the base shear equations shall apply. Building occupancy and function Seismic Base Shear In accordance ASCE-7 code, buildings must be designed to withstand lateral forces that are generated during a severe earthquake. The minimum required design force is given in several equations. Design Base Shear, V= C, W Seismic response coefficient, C,, is the smaller value from two equations: In these equations: C₂ = C₂ < Sp!
