Strength of Fillet-welded Joint Connections: Comments on Correlation Between Classical and Particular Finite Element Approach
Abstract
The paper deals with strength of load-carrying fillet welds with application of two different approaches. First one is calculation by classical/scholar approach while second one is devoted to finite element analysis. The classical approach is concerned with national and European engineering practice. The finite element approach includes the application of particular tool which preserves main recommendations from modern postulations in design of joints. The object of interest is welded beam-to-column joint with different structural elements and the stresses are obtained for two models. It is investigated correlation of results of weld stresses from both the approaches. Direct matching of results was neither expected nor found but basic correlation is revealed within the joint behaviour under loadings. Considering finite element approach as prevailing, its advantage is clearly shown throughout inclusion of local effects of plates. However, classical approach is essential for proper under...standing of joint behaviour and should be always the first step in structural analysis. The usage of at least two different approaches is one way of improving safety checks in engineering and stands for purpose of validation or verification of design.
