Explain briefly about Under reinforced section, Balanced section and Over reinforced section.
Find a suitable angle section to resist a factored tensile force of 200 kN assuming single row of 16 mm bolts. Take yield stress fy= 250 N/mm² and ultimate stress of 410 N/mm².
A perfectly axially loaded concrete column of gross dimension 400mm × 400mm is reinforced with 4 bars of 20mm diameter. Determine the design axial load carrying capacity of the column. Consider M25 grade concrete and Fe415 grade steel.
The rectangular beam of width, 300 mm is having overall depth of 400 mm. The concrete grade is M 20 and the grade of reinforcing steel is Fe 415. The tensile reinforcement is provided by 4-20 mm bars. In the compression side, the reinforcement is provided by 2-16 mm bars. The clear cover is 25 mm. Calculate the additional Moment of Resistance. Also evaluate the stress and strain at compression side and verify that the section is under-reinforced or over reinforced. The salient points of design stress-strain curve of Fe 415 is given by (strain, stress, N/mm²) (0.00144,288), (0.00163,306), (0.00192,324), (0.00241, 342), (0.00276, 351), (0.00380, 360).
