This book presents limit states design procedures for the design of portal frame buildings based on Australian standards.
Portal framed steel clad structures are the most common type of industrial buildings. They find extensive use as industrial factory and warehouse structures, and as indoor sporting venues. The major components of a portal frame building are a series of parallel portal shaped frames as the major framing elements. Each frame is rigid, and resists horizontal wind forces and gravity loads in the plane of the frame by flexural action.
The 5th edition (2023) has been updated to cater for the 2020 steel structures code AS 4100, the 2021 wind code AS/NZS 1170.2 and the introduction of a new methodology for determining the break-out capacity of cast-in holding down bolts. The method of dealing with local pressure patches first presented in the fourth edition has been expanded to provide a two-tiered approach for purlin and girt design with a simpler but conservative primary design option and a more complex secondary option. The deflection limits for crane supporting structures have been changed to better reflect Canadian, US and European practice. However the crane runways and monorails code AS 1418.18 is under revision and further changes including serviceability load requirements may result.
The opportunity has also been taken in the 5th edition to correct some errors and to generally refine and update the previous edition. As in previous editions, the design of bored piers is generally in accordance with the limit states design approach of AS 2159-2009 but with different geotechnical capacity reduction factors proposed depending on whether the piers are classified as short or long. The quadratic expression derived from Broms’ work by the authors for use in determining the lateral load capacity of short bored piers in cohesive soils continues to be presented in the text of Chapter 7. This expression facilitates the preparation of spreadsheet programs for determining the lateral capacity of bored piers.
The book should prove of great assistance to practising engineers as well as students.
