Full-scale experimental study of welded RHS T-joints with offset and it main outcomes

Popis výsledku v původním jazyce

The paper introduces brief outcomes of experimental and numerical studies of the mechanical resistance of welded T-joints composed from rectangular hollow section (RHS) components with certain offset of a brace relative to a centreline of a chord. Program of experimental research includes full spectrum of possible types of the members’ offsets with only one type of the component set - 150x100x4mm for RHS-section used for chords and 50x30x4mm for RHS-section used for brace elements. Results of the T-joints experimental research, together with coupon tests of steel strips which were cut out from the profiles used in the specimens producing, are presented and discussed in detail. Finite element models created from brick finite elements using ABAQUS CAE was developed with the aim of calibration of the numerical models and experimental specimens in frames of presented study. Brief comparative analysis of load-displacement curves obtained in the tests and throughout of numerical analysis demonstrates sufficient convergence that will be used under preparation of program for the future parametrical research.
