📚 Check out our colleagues' educational video on Shear Forces in the Column Web! 📚
Shear forces in the column web often limit the moment resistance of beam-to-column end plate connections, necessitating additional measures like stiffening. In this concise video demonstration, we focus on the behavior of the column web panel under shear, simulated using the #SteelJoints add-on in the #RFEM program by #DlubalSoftware.
Explore the issue and learn how designing unstiffened steel connections with a design-oriented numerical model addresses this challenge. The video compares two configurations of a simple end plate connection:
1️⃣ Beam to column connection from one side only
2️⃣ Beam to column connection from both sides
👉 In the "both sides" connection, moments are equal and opposite, resulting in no design shear in the column web. The moment resistance is limited by the column web in transverse compression.
👉 In the "one side" connection, shear resistance plays a critical role, leading to significantly reduced forces in the upper rows of bolts. Consequently, the moment resistance is lower than in the "both sides" configuration.
📊 The video demonstrates the accuracy of our numerical model assumptions. In the "one side" connection example, failure occurred at approximately 70% of the moment resistance observed in the "both sides" connection, aligning closely with the component method calculations.
