These panels are quite slender to the point where they usually require additional horizontal support to make them stable. The same can also apply to cavity walls, where both skins are incapable of resisting lateral loads.
The element that provides this support to masonry panels is a vertical prop known as a ‘windpost’. Its principal role is to provide lateral support against destabilising horizontal forces that typically originate from wind pressure – hence, the name.
Windposts are typically steel elements – either open sections, such as channels or angles, or closed sections, such as rolled hollow rectangular sections. This Technical Guidance Note provides guidance on the design and detailing of windposts relating to their incorporation into building structures.
Base plates are the primary means by which steel-framed structures transmit vertical loads into their foundations.
This note focuses on the design of columns in simple construction to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings . It covers rolled steel ‘I’ and ‘H’ sections acting as columns within a braced steel frame structure.
This note concerns the design of pile-caps for small groups of piles. It relies on the strut-and-tie method to determine the amount of reinforcement required in the pile-cap; which is dependent upon the depth of the cap, the magnitude of the axial load being placed upon it, the cap’s concrete strength and the pile size and spacing.
