A singly reinforced beam of dimension 200 x 350 is reinforced with 3-25mm at the bottom. If the concrete has a compressive strength of 17MPa and the steel has a yield strength of 415 MPa, determine if the beam can carry a uniform distributed load of18 kN/m dead load. The beam has a length of 5m with 40mm concrete clear cover, 10mm enclosed stirrups, and Es = 200 GPa. Use LRFD in the analysis. QUESTIONS: 1.What is the effective depth of the given beam. (1 decimal) 2.What value of ?1 should you use in the computation. (2decimals) 3.What is the value of the steel reinforcement ratio if a balanced condition is assumed. (4decimals)
