This Technical Guidance Note aims to clarify the term 'simple connection' by explaining its use when designing connections within steel frames. Additionally, guidance is offered on different types of simple connection and the design checks that need to be carried out.
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.
The purpose of a pad foundation is to spread a concentrated force into soil. They are one of the most simple and cost effective types of footings for structures. Provided the founding soil is of sufficient strength and is not too deep to reach, pad foundations are the preferred solution for foundations due to the straight forward nature of their design and construction. This Technical Guidance Note covers the design of concrete pad foundations, both mass and reinforced concrete forms. It will not, however, discuss how the bearing capacity of the soil is determined, as that is explained in Technical Guidance Note 19 (Level 1) Soil bearing capacity. It is suggested that you read that text in conjunction with this, in order to gain a more comprehensive understanding of the topic.
