Course Overview
ABOUT THE COURSE: A thorough understanding on structural stability is essential to structural engineers whose job is to design safe and economic structures. In a structure, a small change in compressive load could cause a large variation in displacement. If this change in displacement is large enough in a critical member of the structure, a local or member instability could lead to collapse of the entire structure. Instability failures is catastrophic.This course explains how and under what loading condition, a structure passes from a stable state to unstable state. Different structural members and systems are analyzed for their stability. This also includes how theory translates into design methods implemented in design guidelines. All major international standard specifications include provisions based on stability theory. Attention is especially focused on metal structures. Compared to structures designed using other construction materials, metal structures rely to a greater extent on stability limit states.INTENDED AUDIENCE: Civil & Structural Engineering/ Mechanical Engineering/Aerospace Engineering/ Naval Structures studentsPREREQUISITES:Mechanics of SolidINDUSTRY SUPPORT: All Structural Engineering Industries.
