- 16. Recommendations on selection of scheme Department of Civil & Structural Engineering When strength of the structure governs design, simple construction should be adopted. When stiffness (serviceability) governs design, greater economy is generally achieved with simple construction. As the region in which the structure is to be designed is not a seismic active zone, continuous construction may not be required.

Editor's Notes
- Our design is Portland house which is a part of reconstruction of a former industrial site close to centre of a large UK town.Up to 3.4 m depth is made ground. From 3.4 m to 9.8 m River Terrace deposits (sand and gravel). 9.8 m to 35.7 m is stiff clay followed by bedrock. The highest ground water level encountered was at 2.0 m depth. The building consists of an underground basement primarily for car parking provided through a ramp, a plant room and elevator and stairs for access to ground floor and residential floors. The ground floor has room for private leisure facilities including a gym, office, café and a saloon. The ground floor is followed by nine luxury residential floors each having four apartments.
- Choice of material – Steel – Reasons, availability, durability, economy, labour cost, sustainability, speed of construction, ability of having longer spans.Our team proposes two structural schemes for this project which are Simple construction and the second one is continuous construction. In simple construction the joints are designed as pin connections which do not transfer moments from beams to column or to other beams. While in continuous construction, the connection is designed to transfer the moment from beams to columns and other beams.Common ElementsThe structural layout for both of the design schemes are primarily same.The foundation for both the structural schemes are proposed to be a raft foundation.The design of the retaining wall for both the design schemes is similar with reinforced concrete walls provided.Both the schemes have the same structural layout so the building will have the same aesthics.
- Continuous beam / column connections substantially increase stiffness of floor systems to ensure serviceability in presence of long spans and/or restricted beam depths.The columns, especially external columns increase in size substantially to resist bending moments.Continuous beam column connections are much more costly both in terms of labour and material than simple connections.The global analysis is complex making it difficult to optimise element sizes.
