A circular concrete column of 300 mm diameter, is reinforced with six identical steel bars. If the column is subjected to an axial compressive force of 800 kN, determine the required diameter of each reinforcing steel bar so that one-third of the load is carried by the steel and two-thirds by the concrete. Assume Esteel= 200 GPa and Econcrete= 25 GPa.
For the data given below, derive the 2-hr unit hydrograph for a watershed having a drainagearea of 216 km^2, assuming a constant baseflow of 20 m^3/s.
Analyze the stability of the dam shown in the figure, if the friction coefficient between concrete and foundation is 0.70, and the specific weights of concrete and water are 24kN/m 3 and 10kN/m 3 , respectively.
How do the crack behaves under the compression of a concrete cubes under friction between the plates and specimen with stress strain diagram?
