A 3-m 150 mm CHB wall rests on a 600 mm thick concrete footing. The CHB wall weighs 3.3 kN/m² and will carry a construction live load of 20 kN per meter length of wall. 24 kN/m3 , 18 kN/m³ , ,fc' = 28 MPa, fy = 248 MPa. Steel cover to bar centroid is 90mm. Pp + PL 600 mm Determine the effective soil pressure if the soil bearing capacity is 130 kPa and the top of the footing is 1.0m from the NGL. Determine the required width of the footing. Determine the magnitude of critical moment at the footing and the spacing of the 16 mm bars. 3 m 1 m

Students are often confused with engineering and design. The term engineering design has two words with different meanings, engineering, and design. The term engineering implies applications of laws and principles of science to design and analyze physica…
