Structural design
Task A: Design a staff lounge in a college which is having size of L=5.5 m x B=2.5 m and as shown in figure 1. Height of hall is 4 m, which is having the elements of the building like beams, slab and columns. Design calculation by using European code of practices, along with Structural detailing with Grade of concrete C (fck= 30) MPa and Steel (ƒyk=500 MPa) in RCC. Assume any other suitable data if necessary. Consider the Variable load as qk= 5 kN/m2, Unit weight of reinforced concrete as25kN/m3. Depthofbeamscouldbeequalto450mmandbreadthequalto250mmandcolumn dimension are Depth300×width250mm and thickness of slab could be considered as 200mm. Do the following:
1. Make suitable analysis of the bay in order to calculate the load on slab, beams and then on columns. [10 marks]
2. Design the slab as it is one-way. [10 marks]
3. Make suitable calculations for reinforcement (bending + shear) for any long span beam for limit state of strength following Eurocode 2. [10 marks]
4. Make suitable calculations for reinforcement (main reinforcement + Shear links) for any one single column for limit state of strength following Eurocode 2. [10 marks]
5. Provide suitable drawings wherever necessary. [5 marks]

Task B: The structure below in figure 2 showed a beam and column house of parking garage. This is a steel structure which includes a beam-truss seated on I-shape columns and beam with struts having a 120mm thick concrete slab, which are connected to the pedestals with fixed supports. Consider the height of structure as 4 m and spacing between columns is S=3 m each with side distance L=3.5 m. Subjected to have Permanent action of gk KN/m2 and Variable action qk of 4 KN/m2 respectively do the following:
For Steel Design
Q1: Make suitable analysis of the frame in order to calculate the load on beams and on columns.
[10 marks]
Q2: Design one beam in each lateral direction of lengths ‘L’ and ‘S’ for ultimate limit state following Eurocode. [10 marks] Q3: Design one column in a vertical direction for ultimate limit state following Eurocode 3.
[10 marks]
The purpose of these tasks is to identify, analyze the forces and design the specific members of the Steel Frame shown in the sketch
a) Design of the truss-beam. (In order to carry out the design of this element, students must consider that truss-beam is seated on the columns with a pin-joined connection.) (Axial force must be calculated through analyzing the forces of the frame including support reactions and adding the applied load on the frame)
b) Draw shear-force and moment diagram of the steel frame (truss-beam may be considered as simple beam for the purpose of this task)
c) Design the column (axial, and moment must be calculated)
