Design Assignment 2: CIVL 3205/9205 SEM 1: 2018 -------------------------------------------------------------------------------------------- Use relevant clauses of AS 3600: 2009 to design a continuous beam with centre to centre spans of 4.5 m (Figure 1). The beam carries a live load of 3.5 kN/m, a superimposed dead load of 2.5 kN/m and the selfweight. The supporting columns at A, B, C and D are 250 mmx250 mm in dimension. In addition to the given load, it needs to support a 2.8 m high brick wall above it. Thickness of the brick wall is 225 mm and the unit weight of the brick partition can be taken as 20 kN/m3 . Take the unit weight of concrete as 25 kN/m3 . This beam is a part of an office building located in a region classifi

The beam carries a live load of 3.5 kN/m, a superimposed dead load of 2.5 kN/m and the self- weight. The supporting columns at A, B, C and D are 250 mmx250 mm in dimension. In addition to the given load, it needs to support a 2.8 m high brick wall above it. Thickness of the brick wall is 225 mm and 3 the unit weight of the brick partition can be taken as 20 kN/m . Take the unit weight of concrete as 25 3 kN/m . This beam is a part of an office building located in a region classified under exposure category A2. Design load 250 mm 4.5 m 4.5 m 4.5 m D A B C Figure 1: Continuous beam Use a 350mm wide 550mm deep rectangular section for your beam with a clear cover of 25 mm. Use 32 MPa concrete. 1. Sketch the design bending moment and shear force diagrams for the given beam at ULS. You must clearly indicate all key values with supporting calculations. [15 marks] 2. Calculate the flexural reinforcement requirement for the beam to withstand the given load under ULS. You must consider all critical locations of the beam and use N16 bars for the flexural reinforcement and N10 for the stirrups. You may use the symmetry of the beam to reduce the repeating calculations. [15 marks] 3. Check the beam for shear and provide necessary stirrups. You must only consider the maximum shear force of the beam. [10 marks]. 4. Analyse the mid-section of the span B-C using transformed method by following the steps below. a. Service moment at mid-span [5 marks] b. Neutral axis depth and the second moment of area of the transformed section [5 marks] c. Cracking moment [10 marks] d. Maximum concrete and steel stresses under the given load [5 marks] -6 Assume design shrinkage...
