Figure Q1(a) shows the first floor structural layout plan for a factory-office building and Figure Q1(b) shows the detailing of beam 1/A-B. The brickwall of 3.5 m height is construct on the beams perimeter (A0/1-2, B/1-2, 1/A0-B and 2/A0-B). Other design data are as follows: All slabs thickness All beams size Characteristic strength of concrete Characteristic strength of steel reinforcement= Unit weight of reinforced concrete Finishes and services Brickwall Variable action (a) (b) (c) = 150 mm = 250 x 750 mm 30 MPa 500 MPa = 25 kN/m³ = = 1.5 kN/m² = 2.6 kN/m² = 3.0 kN/m² Illustrate the load cases to be considered in designing beam 1/A-B. (5 marks) Identify and analyse one of the load case in Q1(a) that will cause maximum sagging moment at span 1/A-B. (20 marks) Based on the analysis in Q1(b) and Figure Q1(b), check if the shear link near support B is adequate. (10 marks)
