To calculate the axial load carrying capacity of steel and reinforced concrete columns

(a) A short reinforced concrete column3.75mm long of square dimensions 350mm square with steel bar reinforcements has 6 no 25mm bars (area= 2950mm2). Determine the axial load carrying capacity of this column. Confirm firstly that the column is short. (PS) (b) Select an equivalent steel column section that can carry this axial load safely and economically stating all your steps.(P6) (A) Describe the concepts of slenderness ratio and effective length in the design of both steel and reinforced concrete columns separately, and comparing them appropriately. (P5) (B) Determine the exact axial load carrying capacity of the selected steel column section provided above. (P6) (C) Explore and analyse the toad carrying capacity, size, weight and corrosion resistance properties of different materials used for beams and columns in fixed structures. (M3) LO4 TASK 4: Explore design methods for steel, reinforced concrete beams and columns A Hotel guest house building one storey high has a beam first floor Identified as Brn long on two simple column supports. The beam is carrying a UDL of 55KN/m. Each column is axially loaded by 4 such identical beams. (A) Develop two design solutions, one in steel and the other in reinforced concrete, for this stated beam and the support column for this given scenario, comparing their corresponding costs for the beam both in steel and in reinforced concrete and also for the column in both steel and reinforced concrete as well. (P7) (B) Produce drawings and specifications in support of the structural design solutions above. (P8) (C) Evaluate the use of an alternative material, different from concrete or steel, in achieving a design solution, discussing the benefits and challenges so associated. (M4) (D) Assess the use of Building Information Modelling in the production of accurate structural design information and the collaborative environment of structural design. (D3)
