It is required to design a combined footing for two RCC columns spaced at 4.5 m C/C. The columns are 350 mm square in size. The characteristic materials strengths are fck = 30 N/mm² for concrete and fyk = 500 N/mm² for the steel reinforcement respectively. Effective cover to reinforcement on all sides = 50 mm. ● Allowable bearing capacity of soil is 201 kN/m² Characteristic axial permanent action on each column 1382 kN ● Characteristic axial variable action on each column 217 KN By referring to the Euro code 2, provide the following: Assess whether the effective depth of footing provided is satisfactory to resist punching shear. Calculate the area and spacing of steel reinforcement required for longitudinal and transverse direction ●
