Introduction The project is to develop a structural design for an arts and culture exhibition space for Royal Borough of Greenwich to promote the history of the surrounding area. The Client, the Royal Borough of Greenwich, wishes to create a landmark building that reflects the cultural heritage of the surrounding sites and the history of the British clipper ship the Cutty Sark (built in 1869). The following elements are NOT required in your design: foundation design, lateral stability, ground floor slab design and reinforced concrete column design.

Design Data Structural Material • Concrete grade to be determined by your group. • Assume fyk = 500 N/mm² steel reinforcement. • Assume S355 steel for all steel members. • • • • Building layout The overall shape of the structure is provided in the attached drawings; however, each group has a target building footprint (area on plan) that they must aim for. You are allowed a +/- 10% tolerance on the final footprint area. Floor heights The ground floor will consists of a car park with a minimum headroom of 4.5 m, columns are permitted on the ground floor. The first floor is to be designed for storage of art items and the Client requires this space to be flexible so it can be used as exhibition space, hence there is no column is permitted on the first floor. The minimum head height is 6 m. The second floor consists of consultation area for placing orders and a café overlooking the River Thames. The planning condition requires that the overall building height shall not exceed 23 m due to issue with line of sights. Structural zone - Include a tolerance and deflection zone of 40 mm and a service zone of 300 mm in the floor depths. Materials • No ground floor design required • • Ground to first floor is reinforced concrete (RC) structure, the thickness of the floor slabs in the RC floor is to be determined by you. First floor and above is to be steelwork, you may assume a floor slab thickness of 150 mm for the steel frame. Loading (Characteristic) First Floor Superimposed dead load [CHECK TABLE] Imposed load for exhibition BS EN 1991–1 (see C11, Table 2) = ? kN/m² Self weight of floor (by you) Second Floor Superimposed dead load [CHECK TABLE] Imposed load for café BS EN 1991–1 (see C11, Table 2) = ? kN/m² Self weight of floor (by you) Coursework Brief Page 4 of 12 Roof (lightweight) Finishes and metal decking Ceiling and Services = 1.20 kN/m² = 0.15 kN/m² Imposed load for roof BS EN 1991-1-1 (See H, Table 2) = 0.60 kN/m² Cladding A cladding load of 5.0 kN/m² (characteristic load) should be allowed around the perimeter of the building to allow for a 'green cladding' system. If you require any additional design data, use your engineering judgement or a reference, stating any assumptions made in your submission. Actions on Structures 93 94 Structural Engineer's Pocket Book (continued) Variable actions: Imposed floor loads The following table from BS EN 1991-1 gives the normally accepted minimum floor loadings. Clients can consider sensible reductions in these loads if it will not compromise future flexibil- ity. A survey by Arup found that office loadings very rarely even exceed the values quoted for domestic properties. The gross live load on columns and/or foundations from sections A to D in the table can be reduced in relation to the number of floors or floor area carried to BSEN 1991-1. Live load reductions are not permitted for loads from storage and/or plant, or where exact live loadings have been calculated.
