RCC Design Test...

If the unsupported length of a column is 3 m and its sides are 240 mm × 360 mm the minimum eccentricity so that the column is designed as an axially loaded column is _______

The reduction coefficient of a long RC column with effective length of 6 m and size 250 × 400 mm is

A column is subjected to direct compression and bending compression both such that the stress developed in direct compression is 2.5 N/mm² and the stress developed in concrete in bending compression is 3.6 N/mm². If M - 20 concrete is used in the column. Then identify which of the following statement is correct

An isolated footing of 2 m × 3 m along the plane of bending moment is provided under the column. If the net maximum and minimum pressure on the soil under the footing are 95 kN/m² and 55 kN/m² respectively and the axial load is 450 kN, then the bending moment at its base will be (The centre of gravity of column and footing coincides)
