A 400 mm x 400 mm column supports a DL = 500 KN, LL = 1000 KN. Assume that the weight of the footing and the soil above is to be 8% of the total service load. The soil bearing capacity is 200 KPa, fc’ = 27.6 MPa, and fy = 414 MPa. Due to some constraints, one of the dimensions of the footing is limited to 2 m. Design completely the footing. Provide the footing plan and elevation.

A 400 mm x 400 mm column supports a DL = 500 KN, LL = 1000 KN, MDL = 600 KN-m, and MLL = 600 KN-m. It is required that the column must be placed at the center of the square footing. Assume that the weight of the footing and the soil above is to be 15% of the total service load. The soil bearing capacity is 209 KPa, fc’ = 27.6 MPa, and fy = 414 MPa. Design completely...

Q1 (10 marks) You have been asked to examine the bearing capacity of several different rectangular pad footings. The width of each of the footings is to remain constant wil vary. In order to reduce the number of calculations, you have decided to plot the ultimate bearing capacity against the length of the footing. The properties of the underlying soil profile are given in Table 1.1. The base of the footing is to be located 1 m below ground level...
