Teised raamatud teemal:
Provides recommendations for the fatigue design of directly welded, unstiffened joints (or connections) between structural steel hollow sections, in uniplanar or multiplanar truss-type structural systems. The recommendations represent the current international consensus on practice. The fatigue design procedure is based on the ‘hot spot stress approach’.


This International Institute of Welding (IIW) report was presented at the 52nd Annual Assembly in Lisbon in June 1999. It contains recommendations representing a consensus on international best practice, focusing on a 'hot spot stress' approach. A wide range of joint types is covered, the new fatigue design curve for both RHS and CHS is dealt with and detailed values for stress concentration factors are provided. The purpose of this current IIW document is to serve both as an International Standards Organisation (ISO) draft specification and as a model standard for national and regional specifications worldwide. The Recommendations (Part 1) and Commentary (Part 2) were edited by Dr X-L Zhao of Monash University, Australia and Professor J A Packer of the University of Toronto, Canada.
