PART A Task Description: You have been asked to provide structural engineering consulting services for a residential project. The project is a three-storey residential building, with a structural steel frame, composite concrete-steel slabs, and a flat roof supported on timber joists. The client has provided you with the architect’s sketches, which, however, might be inaccurate from a structural perspective. A junior structural engineer in your practice has also done some calculations, based on the architect’s sketches, and provided you with the following information: • permanent loads on the roof groof = 0.9 kN/m2. • permanent loads on the slabs are gslab = 1.2 kN/m2. • permanent loads of the walls are gwalls = 5.0 kN/m. The above do not include the self-weight of the load-bearing structure. Variable loads and permanent loads due to self-weight of the members are not provided: suitable loads should be identified from the relevant structural design codes. For this project: a. Design the timber joists of the flat roof according to the Eurocodes. (10 marks) b. Design the composite concrete-steel slab according to the Eurocodes. You will need to take into account both the final case (with the slab completed) and the construction phase (when the slab is being poured) (15 marks) c. Design the structural steel frame according to the Eurocodes. (15 marks) d. Provide the structural drawings you consider necessary to describe the design for architectural and construction purposes. As a minimum, you should include General Arrangement drawings of all the floors in plan view, and at least two elevations, accompanied by the necessary schedules of members. (10 marks) PART B Description: The contractor has asked you to carry out a numerical analysis of the structure designed in Part A, utilising the Finite Element Method (FEM) via appropriate software. For this project: a. Describe both the theoretical background and procedure of the numerical. phases covering the computational method of FEM and software use. 20 marks b. Model and analyse two-dimensional structural ANSYS model for each individual structural member (beams, columns and slabs). 10 marks c. Present the stress, deflection, shear force, and moment distributions in individual structural members. Validate the numerical results with the calculations done in Part A for a steel column, a steel beam and a concrete slab, and discuss the results. 20 marks The discussion should be supported with external sources, appropriately cited and referenced. It should also include appropriate sketches, images, and diagrams to support the results. I have uploaded the relevant materials and require the writer to have a look and see whether they are capable of completing the assignment, the writer will then inform me of how many pages are needed to ensure the assignment is complete to gain the highest grade possible.
