A footing of size 2.5 m x 2.5 m and 500 mm thick resists characteristic axial loads of 800kN dead and 300 kN imposed from a 400 mm square column. The safe bearing pressure on the soil is 230 kN/m2 and the characteristic material strengths are fcu = 35 N/mm2, fy=460N/mm2. Density of concrete is 24 k N/m3. Cover to all reinforcement is 50 mm. Determine the design load b) Check whether the base pressure is safe c) Design the bending reinforcement, assuming 16 mm diameter bars.

1) Design a rectangular footing for an 16” square corner Column with PDL = 280 kips and PLL = 180 Kips. Make the length of the long side about 1.5 the width of the short side. Fy = 60 ksi F’o= 4000 psi for both, column and footing. Assume the base of the footing is 4'-6" below grade and the depth of the footing is 26". The soil weight is 100 PCF. (Normal weight concrete, No epoxy coating, The Column is reinforced with eight #8 bars.) Need to design for load transfer from the Column to the foating. Need to Show the development length for the dowels. Need to design the bars for footing at both directions. Need to check if the bars fit the footing based on the development legth. Need to show two-way footing Spacing diagram.

B Calculate the ratio of the Ultimate Shear Force to Shear Capacity in one-way shear. Consider critical case only. A rectangular footing has dimensions shown and is acted upon by a dead load of 653 kN and a live load of 647 kN. The column dimension is 269x677 mm where the shorter dimension is parallel to B. The thickness of the footing is 442mm. f'c-28 MPa and fy=420 MPa for diameter 20mm bars. A=2.9m and B=4.8m
For a sandy soil, the ultimate bearing capacity of 30 cm plate is found to be 120 kN/m² cm during plate load test. Then the ultimate bearing capacity of a square footing of 80 cm side under same loading conditions is se VERDDIEREDDIDD DDDD DDOME2Dan
QUESTION 2 A square column with side dimension of 20 mm rests on top of a timber footing. It is determined that the column carries an axial load of 591 kN. If the punching strength of concrete is 19.86 MPa, determine the minimum thickness (mm) of the footing.
True or false? For reinforced concrete footings, the size is calculated to satisfy the bending and shear strength of the concrete footing.
