Assignment Brief and Guidance

• 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 ofboth.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.

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.). Please 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)

• loads on the building long wall due to wind

• 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.

• Discussthe relationship between the building form and wind loads.

• Provide calculationsforstiffening than may be required.

Cantilever

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/2m. Calculate the bending moment , Deflection and shear force.

Design the same beam using Reinforced concrete in order to select the most appropriate. Calculate the bending shear and deflections.

• Evaluate the types of connection that will be needed to provide the cantilever and design.

• Discuss the relationship between bending, shear and deflection.

• Critically evaluate steel and reinforced concrete and their structural efficiency in managing bending, shear and deflection.  

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

• Give three examples of different types of tensile structures.

• 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.
