| description | This report presents a numerical study on high strength steel S690 channels connected to gusset plates in tension. An experimental study of 18 test specimens, among which consists of different section sizes, bolt sizes, bolt patterns and connection lengths, had been reviewed as benchmark tests. The numerical modelling by finite element (FE) analysis was carried out, including a validation study to assess numerical models’ accuracy in replicating the experimental tests and a parametric study to generate more data. In the validation study, results from FE models were compared against those from experimentation in terms of load-elongation curves, failure loads and failure modes. The application of numerical modelling was then validated, and parametric studies were carried out. A total of 74 FE models were constructed, including 19 2-bolt connections, 27 3-bolt connections and 28 4-bolt connections. The geometric variation, in terms of section sizes, bolt sizes, bolt patterns and connection lengths, of the FE models were fully presented. Results of the parametric study were analysed and recorded, and the effect of eccentricity and connection length towards the performance of the models were also discussed. From the result analysis, it was revealed that higher eccentricity leads to a higher secondary bending moment of the connection, eventually resulting in lower resistance of the connection. In addition, an increase in connection length provides rigidity and strength to the connection, hence increasing the resistance of the connection. Lastly, the results from experimental testing and numerical modelling were compared to several international design codes. The accuracy, conservativeness, and applicability of the design equations for HSS channels connected to gusset plate in tension in accordance with (i) European Code EN 1993-1-12, (ii) American Specification AISC 360-10 and (iii) Australian Standard AS 4100 was assessed. Through the assessment, it has been revealed that European Code EN 1993-1-12 provides the most conservative predictions, followed by Australian Standard AS 4100 and lastly, American Specification AISC 360-10 provides the least conservative predictions. |
