Question 44620

Structural Analysis

A structural engineer has hired you to design square concrete unembedded footings for a building, based only on capacity. Each footing will hold an axial load of 340 kN. Your technicians have conducted lab tests on specimens sampled from the site, and they report the following profile: a 0.8m thick clay layer over a 7m thick clayey silt layer (the clayey silt layer lies over rock). The lab report reveals that the clay has a friction angle of34 degrees and an undrained strength of 35 kPa, and that the clayey silt has a friction angle of 37 degrees and an undrained strength of 45 kPa.
Determine the size of one of the footings, in meters, such that the critical actor of safety against a capacity failure is as close to 3 as possible, but still larger than 3 and smaller than 3.2. The other (non-critical) factor of safety must be greater than 3. Express your answer with a resolution of 0.1 meters. That is, values of B of1.2, 2.3, 3.4m, etc., for example, are acceptable, whereas B values of 1.21, 2.32, 3.43m, etc., for example,are not.
Show all your work, organized, and circle your answer for B.
