A reinforced concrete column contains longitudinal steel equal to $$1$$ percent of net cross-sectional area of the column. Assume modular ration as $$10.$$ the loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are $${P_s}$$ and $${P_c}$$ respectively. The ration $${P_s}$$/$${P_c}$$ expressed as percent is

A rectangular column section of $$250\,\,mm \times 400\,mm$$ is reinforced with five steel bars of grade $$Fe$$ $$500,$$ each of $$20$$ $$mm$$ diameters. Concrete mix is $$M30.$$ Axial load on the column section with minimum eccentricity as per $$IS: 456$$ - $$2000$$ using limit state method can be applied upto

An $$RC$$ short column with $$300\,\,mm \times 300\,mm$$ square cross-section is made of $$M20$$ grade concrete and has $$4$$ numbers, $$20$$ $$mm$$ diameter longitudinal bars of $$Fe$$-$$415$$ steel. It is under the action of a concentric axial compressive load. Ignoring the reduction in the area of concrete due to steel bars, the ultimate axial load carrying capacity of the column is

Design a square $$R.C$$ column to resist an axial load of $$400$$ $$kN$$ due to dead load and $$240$$ $$kN$$ due to live load at service stage. Design the section as a short axially loaded column. Use $$M25$$ concrete and steel of grade $$415$$ $$N/m{m^2}.$$ Give a near sketch of the cross section.
