PROBLEM IOI: A continuous strip footing is to be located concentrically under a 300 mm wall that delivers service loads D = 360 kN/m and L= 220 kN/m to the top of the footing. The bottom of the footing will be 1.2 m below the final ground surface. The soil has a density of 20kn/m² and allowable bearing capacity of 280 kn/m² Materials strengths are f' =21 MPa and fy = 276 MPa. Find: Referring to problem 101, design the footing considering the moments induce by the following loads given below in addition to the service loads: MD = 50 Kn-m ML = 60 Kn-m ME = 36 Kn-M Use the following load combinations: U= 1.2D + 1.6 L U = 1.2 DL + 1.0L + 1.0E a. The required width of footing, b. The required effective and total depths, based on shear, c. The required flexural steel area. d. Give an on-scale schematic structural detail. ***Use 20 mm Ø
