Question

10.10 A 300 mm x 450 mm plate was used in carrying out a plate loading test in a sand, during which the plate settled 5 mm under the applied pressure of 250 kN/m2 a. What is the coefficient of subgrade reaction for a 300 mm wide square plate? b. What would be the coefficient of subgrade reaction of a 2 m X 3 m foundation? For a 2.0 m wide and 0.40 m thick beam on an elastic foundation, determine the coefficient of subgrade reaction k using Eqs. (10.45) and (10.46), assuming the following pa- rameters: E, 30 MN/m2, Er 30,000 MN/m2, u, 0.25. 10.11
