This Technical Guidance Note focuses on the visualisation of structures. It is essential for structural engineers to be able to express their ideas clearly through their designs. Visualising structures in the appropriate way enhances the design process - not least because drawing the complex elements of a structure while carrying out calculations, can help to identify possible construction issues/problems at an earlier stage than may otherwise be possible. This guide explains two techniques that are commonly used to draw in three dimensions and thus aid the structural engineer in visualising the structures they design.All of the guides in this series have an icon based navigation system, designed to aid the reader.
When developing a scheme for a structure, the choice of floor slab construction is critical to the columns, foundations, walls and overall stability. As such, the floor slab’s form should be selected with care and consideration. 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. building services) 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 Technical Guidance Note is an introduction to the assessment of floor vibrations. Since the adventof lighter structures that have longer spanning elements within them, the built in dampening effectbuildings have had historically has become less pronounced. Despite this, floor vibration canbe an overlooked criterion during the design process. This can lead to expensive remedial works being carried out on structures after they have been built, as occupants complain of discomfort due to excessive movements and vibrations.
