Plastic Analysis Fundamentals for Structural Design

Understanding how structures behave beyond their elastic limit is essential for safe and efficient engineering design. This text-based course introduces you to the core principles of plastic analysis, helping you predict collapse mechanisms and calculate true structural capacity. By reading through our clear explanations and working through practical written problems, you will transition from basic elastic concepts to advanced plastic design principles. You will gain the skills needed to determine collapse loads for beams and frames, applying these concepts to real-world structural engineering scenarios. What you'll learn: - Learn the fundamental differences between elastic and plastic behavior in structural materials. - Calculate shape factors and plastic moment capacities for various cross-sections. - Identify collapse mechanisms in beams, portals, and multi-story frames. - Apply the upper and lower bound theorems to solve complex structural analysis problems. - Understand modern limit state design principles and how plastic analysis aligns with current building codes. - Practice step-by-step calculations through guided written exercises and structural scenarios. The course begins with foundational concepts of stress-strain relationships and yield criteria, before progressing systematically to plastic hinge formation, collapse mechanism analysis, and practical design applications. Designed for engineering students, junior structural designers, and anyone seeking a solid foundation in plastic analysis, this course requires no advanced prerequisites beyond a basic understanding of engineering mechanics.
