This Technical Guidance Note describes the concept of biaxial bending of columns, as well as the effect direct bending has on column design. The guidance given here can be applied to columns made from any material, be it steel, concrete, timber or even glass.
This Technical Guidance Note concentrates on the design of reinforced concrete columns to BS EN 1992-1-1 – Eurocode 2: Design of Concrete Structures – Part 1-1: General Rules for Buildings. It covers the design of columns of all cross section proﬁles, which are typically square, rectangular and circular.
This Technical Guidance Note describes the design and detailing of base plates – the primary means by which steel-framed structures transmit vertical loads into their foundations.
