19. A continuous beam as shown has an effective depth d=540mm and is designed to carry a factored UDL load of 200 kN/m. For the end supports the ultimate shear force used for the design of shear capacity of the beam is: 600 300 4200 4200 300 300 4200 300 a) 405 kN b) 375 kN c) 267 kN 20. In RC column design, which of the following statement(s) is/are true? a) tensile stress is not allowed to occur in columns. b) the length of a long column must be longer than the length of a short column. c) Bending moment due to connecting beams is ignored in the equation: N = 0.35f A +0.67f, Axa d) None of above 11
