This approach has been included in Section 2.2.5 as an alternative to selecting the steel qualities according to Table 2.2. Part 1.10 Material toughness and through-thickness properties’, allows fracture mechanics to be used to determine toughness requirements.
UK suppliers and distributors of structural fasteners shall comply with National Highways Sector Scheme 3 (NHSS3) or an equivalent quality management system.Additional definitions for terms used in BIM have been added and Sections 1 and 3 of the NSSS have been updated to include the BIM information required and provided by the steelwork contractor. Information is increasingly exchanged in electronic format and on government projects Building Information Modelling (BIM) is mandatory.Various clauses throughout the NSSS have been modified to make it clear that under the Construction (Design and Management) Regulations 2015 all parties have a duty to cooperate with others involved in the construction of the works.The main changes between the 5th edition (CE Marking version) and the latest 6th edition are: Specifiers are encouraged to use this latest NSSS as the default specification for all steel building structures.” The 6th edition can be used for all types of building construction designed for static loading and is based on Execution Class 2 structural steelwork designed in accordance with BS 5950-1 or BS EN (including BS EN and BS EN ) and executed in accordance with BS EN 1090-1 and BS EN 1090-2.īCSA Director of Engineering Dr David Moore said: “The NSSS clarifies and aids the process of translating designers’ requirements into specific work instructions for execution.
The British Constructional Steelwork Association has published the 6th Edition of the National Structural Steelwork Specification for Building Construction (BCSA Publication No. The 6th edition of the NSSS is an invaluable tool for specifiers and designers of steel structures
