In the upcoming analysis, we will once again examine the contact stress between a steel base plate and a concrete foundation, this time focusing on biaxial bending. The illustrations 👇 demonstrate how the contact stress is distributed for 4️⃣ different column cross-sections:
🔹 I-shaped (without stiffening)
🔹 I-shaped (with stiffening)
🔹 Square Hollow Section (SHS)
🔹 Circular Hollow Section (CHS)
Each example represents various combinations of major and minor bending moments. As the ratio between these moments changes, so does the contact stress distribution.
👉 Dlubal Software tools can calculate the contact stress distribution for any combination of applied forces over a wide range of cross-sections, stiffening elements, anchoring options, and base plate shapes. Proper consideration of contact stress distribution is crucial for the design of steel base plate connections.
