This Technical Guidance Note provides information about a number of common floor construction forms that are currently available. It focuses on concrete based solutions: some acting compositely with steel elements,such as reinforcement and/or steel members. Descriptions of each flooring system together with their key features (which cover topics such as buildability, aesthetics and compatibility of other elements e.g. buildingservices) are included. Please be aware that floor slab technology is continually evolving and that new floor slab solutions continue to become available as a result.
(This article was updated in October 2016 to reflect errata issued since its original publication.)
This note describes the basic knowledge required to read structural drawings.
Dead loads (permanent actions) are defined as the weight of static materials contained with a structure. This includes the self weight of the structure as well as the fixed materials it is supporting.
When designing foundations (from a simple pad footing to a pile cap) there is a need to determine the soil's bearing capacity. This note explains the principles of how this is determined, and how it impacts on foundation design.
