摘要：

The present paper concerns the prediction of stress concentration factors (SCFs) of multi-planar welded tubular (CHS) XX-joints in steel structures. SCFs are used in the fatigue design of tubular joints for the calculation of the joint hot-spot stress. Extensive computational research employing finite elements has been conducted, supported by experimental evidence, which resulted in a large SCF data base for multi-planar joints. Using this data base, a simple and efficient methodology has been developed to predict stress concentrations in XX-joints under various loading conditions. The SCF results are presented in the form of parametric equations and diagrams to be used by design engineers in everyday practice. This approach is aimed towards a simple and efficient tubular joint design of tubular structures subjected to repeated loading. (C) 1999 Elsevier Science Ltd. All rights reserved.
