As shown in fig.1, the left column is located near the property line thus individual footing cannot be provided because space available on the left side of the column is not sufficient. As a structural engineer, you have to come up with a solution for the foundation of the left column. Following are the data provided by the geotechnical engineer,[Odd roll] Allowable bearing capacity, qa = 3 ksf at depth, Df = 8ft.[Even roll] Allowable bearing capacity, qa = 5 ksf at depth, Df = 4ft. Column reactions at a base level from the building analysis are,[Odd roll]Column size, b1 = 12in, h1 = 12in, b2 = 20in and h2 = 16in. Axial force: Due to dead load for column C1 is 100kips and for column C2 is 300kips. Due to live load, C1 = 90 kips and C2 = 150kips. Bending moment: Due to wind load for column C2 being 100k’ and due to live load, C2 = 25k’
