Abstract:

A mixture of legislation, public opinion and social responsibility has driven construction industries throughout the world to reduce pollution and waste as part of its drive for greater efficiency, improved quality and greater certainty in the delivery of construction projects. For multi-storey buildings, the use of precast slabs in the floors - particularly if this can be done without the need for in-situ screeds - drastically reduces the volume of on-site concreting required. Although the use of precast hollowcore slabs in steel framed buildings are common, the use in composite design with steel beams is relatively new. By designing the steel beams and precast hollow core slabs compositely, a reduction in beam sizes and overall floor depth can be achieved, which would lead to an overall reduction in construction cost. This presentation summarises the on-going research and developments on composite steel � precast hollowcore constructions.
