Question 1

Part A) Develop a basic Finite Element Model using STRAND 7, guided by the technical specifications provided for the composite steel-concrete beam floor system (refer to Figure 1) and the relevant data for the primary and secondary beams (see Table 1).

Figure 1. A composite steel concrete beam floor system

The above steel concrete beam floor system has the following properties:

• Live load = 3 kPa

• Slab thickness is = 250 mm

• Concrete strength is f'c = 40 MP

• Primary Beams (PB) = See Table 1

•   Secondary Beams (SB)= See Table 1

• Column = SHS 1000 mm × 1000 mm × 150 mm

Table 1. Secondary and Primary Beams in different cases

Case Number	Secondary Beams	Primary Beams	Thickness of Slab (mm)	Live Load (kPa) = Q	Load Combination 1 = 1.2 ×Dead Load + 1.5 × Live Load	Load Combination 2 = Dead Load + 0.4 × Live Load

A-1) Calculate the maximum deflections in the secondary and primary beams for various scenarios (2.5 marks).

A-2) Determine the fundamental frequency of the composite beam floor system under different conditions (2.5 marks).

Part B) Using  your  engineering  judgment,  explicitly  establish  a  technical relationship  between  the  maximum  deflections  (either  in  the  secondary  or primary beams) caused by the self-weight in the different simulated floor systems and the fundamental frequency derived from STRAND 7 (4 marks).

Hint: Support your answers with Strand 7 diagrams,figures, and theoretical understanding as you see fit.

Question 2: Provide  brief technical  comments  on  each  photo,  highlighting potential technical issues or offering recommendations to enhance construction techniques (maximum 50 words per photo) (5 marks).

Question 3: A new research and manufacturing

Assumptions (6 Marks)

A new research and manufacturing facility consisting of two manufacturing floors at Levels 2 and 4 on the South Wing with ancillary research accommodation on all remaining levels in

the North and South Wings.   See Figure Question3.

The building is to be constructed on a sloping site. There is an existing access road running West/East through the centre of the building which cannot be obstructed.

The manufacturing floors are to have a clear internal floor-to-ceiling height of 7.0m. One row of internal columns is permitted within the floor area.

The research areas are to have a clear internal floor-to-ceiling height of 3.5m. One row of   internal columns is permitted within the floor area. A clear 200mm service zone is required between the ceiling and the underside of the structure.

The elevations are to be fully glazed and external columns are to be at a minimum spacing of 5.0m.

In addition to the primary core area indicated on Figure Question 3, two secondary cores as outlined on Figure Q3 are required in both the North and South Wings.

Requirements: Prepare general arrangement plans, sections, and elevations to illustrate your desired floor system's approximate dimensions, layout, and proposal. These should include the structural elements and critical details necessary for estimating purposes. A preliminary sketch or a detailed technical drawing with annotations is expected.

Note: You are not expected to do any calculations for this question.

You may make necessary technical assumptions if any information is missing but be sure to document them explicitly
