Introduction to Structural Steel Design and LRFD Principles

Structural steel is the backbone of modern infrastructure, but designing safe and efficient steel elements requires a solid grasp of engineering fundamentals. Understanding how loads distribute and how materials behave under stress is essential for any aspiring structural designer. This course guides you through the foundational principles of structural steel design using the Load and Resistance Factor Design (LRFD) method. Through clear written explanations and practical calculation examples, you will learn to evaluate structural safety, design individual members, and understand how they connect to form stable systems. What you'll learn: Understand the core principles of the LRFD method and structural safety limit states; Analyze dead, live, and environmental loads acting on structural steel frames; Design steel elements subjected to tension, compression, bending, and shear forces; Evaluate bolted and welded connection configurations for structural integrity; Apply modern design standards and sustainable steel selection criteria to your projects. The course begins with essential terminology, structural steel properties, and safety philosophies before advancing to detailed member design. You will then explore standard connection methods and conceptualize complete structural systems through step-by-step written walkthroughs. This course is designed for beginners in civil engineering, architecture, or construction management, requiring no prior experience in steel design.
