For your coursework, all the loads/actions applied on the structures that you are going to analyse and design depend on your uniqueness code (UC). Your Uniqueness Code (UC) is made up from the SUM of the third and sixth numbers of your student ID number and calculated as follows below.(Please make sure that you hand in this information with your coursework report):
Third number of your ID NO. = 3
Sixth number of your ID NO. = 3
Your Uniqueness Code (UC) = 6
4.2.2. Brief for Coursework Structural analysis, design and detailing
A client wishes to utilise an open area to construct a three storey building with the height of each storey of 3.6m. An architect has been appointed and has evolved the scheme which is sketched in Figure 1.
It has been assumed that the building floor between columns 1 and 5 adopts steel- concrete composite floor, which is supported by composite beam and steel column. However, the building floor between columns 5 and 6 uses in-situ casting concrete floor, which is supported by concrete beam and concrete column.
The characteristic variable action on both floors qk =1.0UC (kN/m2) (Note, use your UC value to calculate the variable action for your structural analysis + design).
All the steel beams and columns are in S275 and UKB section. The materials and further design information of the reinforced concrete slab, beam and column follow below:
Concrete grade 35 (fck=35 N/mm2)
Maximum aggregate size =20 mm
Main steel reinforcement – high yield steel (fyk=500 N/mm2)
Transverse links – high yield steel (fwyk=500 N/mm2)
Diameter of main longitudinal steel () = 25mm
Design tensile strength (fctm) = 3.5 N/mm2
Assume 15% moment redistribution (i.e. = 0.85).
Architectural requirements limit the maximum overall beam depth to 800mm
Maximum interior span/effective depth ratio should not be greater than 18.
As a structural engineer, you have been asked to carry out the structural analysis, design and detailing of this multi-storey building with the main tasks listed below:
Q1. Introduction to the problem and to structural grid. Explain the measures you have to take to improve the stability of the structure.
Q2. Estimate the sizes of all slabs, beams and columns, and carry out load calculations for one typical slab and beam.
Q3. Carry out manual structural analysis to determine the effects of actions on one typical slab, beam and column.
Q4. Use the LUSAS to carry out structural analysis to determine the effects of actions on one
Q5. Design steel-concrete composite slab.
Q6. Design steel-concrete composite beam.
Q7. Design steel beam and column connection
Q8. Design continuous concrete beam.
Q9. Design concrete column.
