Tension Field Action in Plate Girder - An Application of Post-Critical Buckling in Thin Plates

This lecture explores the concept of tension field action in plate girders as a practical application of post-critical buckling behavior in thin plates. Learn how thin web plates in steel girders can continue to carry loads even after buckling occurs, through the development of diagonal tension fields. The 37-minute presentation examines the theoretical principles behind this structural phenomenon and its importance in the design and analysis of efficient steel structures.
