Q1 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: 150 mm = 250 x 750 mm = 30 MPa Characteristic strength of concrete Characteristic strength of steel reinforcement= 500 MPa Unit weight of reinforced concrete = 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. All slabs thickness All beams size Finishes and services Brickwall Variable action (a) (b) (c) (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)
