Stress Analysis of Stud by Changing Shape of Web Opening
[Purposes]Based on the change of the shape of the web hole,the stress characteristics of the stud connector were studied.[Methods]A precise finite element model was established to observe the stiffness difference of the stud at different positions and under the shape of the hole by changing the shape of the hole,and the approximate calculation formula of the stud lift was obtained through the stress cloud map.[Findings]Stress concentration occurred at the opening of the web portal,which was the most prone to failure.As a result,the mechanical properties of the stud directly above the opening of the web portal were the weakest,and its slip amount was significantly greater than that of other positions.At the same time,changing the shape of the opening did not change the overall trend of the curve much.The results of stress nephogram are in agreement with those of stress model.[Conclusions]The research re-sults can provide reference for other similar engineering research.
