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 new 4th edition has been almost completely rewritten to account for changes in the loading codes particularly the new wind code, the availability of new purlin and girt sections and ASI's publication of new connection manuals. New design capacity tables for horizontal SHS struts up to 400x16 Grade 450 SHS are included and design capacity tables for crane runway beams and monorails have been updated and expanded. The information and design guidance on monorail cranes has been significantly expanded and design examples added. A method of dealing with elongated local pressure patches is presented including patches with the new local pressure factor of 3.0. There has also been the opportunity to correct previous errors and to generally refine and update the previous edition.
The book should prove of great assistance to practising engineers as well as students.
