Assignment Brief and Guidance
SCENARIO
• The Client who is a private investor needs a three storey, framed college building. The building frame provides the structure for a series of high specification lecture rooms , exhibition hall and meeting rooms which are intended to be built in the south of England, around Heathrow Airport. The college block can be developed with steel or concrete or a combination of both.
The college block has a plan dimension of 50m by 30m. Height of each storey is 3m. The span of the beams and columns can be chosen based on RC or steel frame. Outside the college building, there is a space to be used for exhibitions which needs to be covered with a tensile structure.
Submission Format
Part 1 – Wind loading
Calculate the following wind loads for the above scenario. For the basic wind speed Vb choose a city name
starting with your first initial. (If you can’t find any city named with your first initial use the second letter of
your first name.).
Write all the formulas clearly and referring to the clause no, figure no or Table no of the standard you are using. Assume the wind blowing towards the longer direction of the building.
• Dynamic wind pressure (for the city starting with your first initial)
• Wind Load on the building long wall.
• Overall lateral load on the building due to wind
• Uplift load on the roof.
In addition, you are to:
• Discuss methods to resist/manage wind loads.
• Discuss the relationship between the building form and wind loads.
• Provide calculations for stiffening than may be required
Part 2 – Cantilever Design
• Design a cantilever beam of span 4m using 275 grade steel. The beam is carrying a Dead load of 10kN/m
and an imposed load of 15kN/m. Calculate the bending moment, Deflection and shear force.
• Design the same beam using Reinforced concrete. Calculate the bending shear and deflections.
• Evaluate the types of connection that will be required for the cantilever beam.
• Discuss the relationship between bending, shear and deflection.
• Critically evaluate steel and reinforced concrete and their structural efficiency in managing bending, shear and deflection.
Part 3- Column Design, Foundations types
• Design the columns with eccentric loading in grade 275 steel. The reactions from beam A and Beam B are
given in the figure below. Apply the moment on the column due to the eccentricity as stated in BS5950
HNC/HND Construction and the Built 4
• Prepare design information required for the given scenario, utilising piled foundations and steel columns.
Also calculate the loads on the piles and select a suitable diameter of reinforced concrete pile.
• Discuss the benefits of using Building Information Modelling in the design workflow.
• Assess the most effective foundation type for a given scenario in terms of ease and speed of
construction, economics, safety and environmental factors.
Part 4- Tensile Structures
• Give three examples of different types of tensile structures.
• Analyse and Design a truss in grade 275 steel to support the Dead load of 8kN/m and
imposed load of 12kN/m. The span of the truss is 8m.
• Provide the general design criteria for tensile structures.
• Provide two different design solutions for the exhibition space roof in the given scenario.
• Compare the two tensile solutions to a given scenario.
• Choose one of the tensile structures suggested for the given scenario and justify your selection.
