This guidance note pays particular attention to partial factors with reference to BS EN 1990: Eurocode – Basis of structural design, to illustrate how extreme events are approached within a code of practice, and explains how the code interprets the application of loads/actions for the design of structures for such events.
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.
A description of the various forms of retaining walls currently in use. This note is primarily concerned with structures that retain soil.
