The beam, shown below, carries an ULS UDL of w. . 150kN/m. It is supported on 375mm x 375mm square columns. 

Assume           B1 classification            f'_c 50MPa               30mm cover 

Your boss has asked you to

a) Calculate the maximum design moment M* for both sag and hog. [Statics] b) Calculate the maximum design shear V* in both the 8.2m span and the 3m cantilever. [Statics] c) Calculate the minimum required A (mm) for both hog and sag [C18.1.6.1] d) Calculate the required Hog and sag reinforcement in mm e) Sketch the actual reinforcement provided - nominate bar diameter and total number of bars AND sketch the bar layout e.g. 4N20 indicates a total of 4 N20 bars f) Calculate the shear reinforcement required at the critical shear location adjacent to both support A and B - nominate bar diameter, number of legs and spacing. E.g.3N12-200 indicates shear reinforcement of 3 legs of N12 bars at 200mm centres. 750mm 800mm 375mm 150mm 8.2m I 375mm Typical Detail to Support CL 3m
