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 Technical Guidance Note describes the basic knowledge required to read drawings produced by structural engineers.
This Technical Guidance Note concerns the derivation of dead loads. This is a core guidance note and as such, subsequent notes will make reference to this one. It is therefore important to understand the contents of this note before attempting to digest any of the others. Dead load is defined as the weight of static materials contained with a structure. This includes the self weight of the structure as well as the materials it is supporting that are fixed to it. Within Eurocode 1 it is defined as a 'Permanent Action'.
This Technical Guidance Note concerns lateral loads that are applied to barriers and wheel axle loads from vehicles. Barrier loading is dealt with slightly differently to other forms of imposed loading. The nature of the loading can vary from people leaning against barriers to vehicles colliding with them at speed. Axle loading from vehicles has to be treated somewhat differently to other forms of imposed loading. While it is possible to assume a blanket area load to represent them, it is the point load from each wheel that needs closer attention.
