Q4). A steel column circular in cross-section is 180 mm in diameter and carries a load of 1.4 MN. The length of the column is 4 m and the density of concrete is 2500 kg/m. Calculate the following based on linear elastic theory: The compressive stress at the top of the column, mid span and at the bottom. How does the stress vary along the length of the column if the weight of the column is included (i.e. linear or curved)? a). b). The length of side of a square steel base plate to transmit the column load to the concrete foundation block (permissible stress on the concrete is 5.5 N/mm²). You must include the weight of the column above. The density of steel is 7700 kg/m3. Assume the steel plate thickness is 10 mm. c). Assuming the concrete base to weigh 180 KN, calculate the plan dimensions of the concrete foundation so that the stress on the soil does not exceed 250 KN/m?.
