This note describes the different types of pile, the design concepts employed when determining their size and depth, how they are constructed and the various tests that can be carried out to assess a pile's integrity.
This note focuses on the design of non-composite steel beams to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings . It covers both restrained and unrestrained rolled steel ‘I’ and ‘H’ beam sections. Updated in October 2016.
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.
