Design of Steel Members for Axial Loads is a practical engineering course focused on forces acting directly through the longitudinal axis of structural elements. It bridges the gap between structural theory and code-compliant design for elements undergoing tension and compression—the fundamental building blocks of skyscrapers, industrial plants, and bridges. Learners will progress from calculating net areas and shear lag in tension members to evaluating buckling limits in compression members. The curriculum extends beyond standard rolled sections to cover high-capacity built-up columns (laced and battened) and culminates in the comprehensive design and connection detailing of industrial roof trusses Learning Objectives By the end of this course, learners will be able to: Calculate Tensile Strength: Determine capacity based on gross yielding, net rupture, block shear, and shear lag effects. Evaluate Buckling Limits: Predict elastic and inelastic column buckling using effective length and column strength curves. Design Built-Up Columns: Proportion laced and battened compression members according to strict code requirements for shear and slenderness. Analyze & Design Trusses: Distribute environmental loads across a roof truss, optimize member selection, and detail joint connections. Ensure Code Compliance: Apply standard steel design codes to deliver safe, efficient, and economical structural solutions. Target Learners & Background: Civil & Structural Engineering Students Early-Career Design Engineers Fabricators & Detailers

Syllabus

Tension Members

This module introduces the behavior and applications of tension members used in steel structures. It covers different shapes, connections, and factors affecting their strength such as net area and shear lag. Various failure modes are discussed to understand member performance. The module also focuses on the step-by-step design of tension members and related components like sag rods and lug angles.

Compression Members

This module focuses on the behavior and classification of compression members including columns and beam-columns. It explains the concept of buckling through theory, experiments, and real-life examples. Factors influencing buckling strength and different failure modes are explored. The module concludes with the design of compression members using standard procedures and column curves.

Built up Compression Members

This module deals with built-up compression members formed by combining structural elements. It covers types such as laced and battened columns along with their applications. The buckling behavior and design requirements of these members are discussed in detail. Practical design procedures are applied to design built-up columns with real-world insights.

Roof Trusses

This module introduces trusses, their assumptions, types, and applications in structures like roofs. It explains load distribution, structural behavior, and analysis of trusses. The selection of suitable sections and connections is also covered. The module culminates in the design of roof trusses through systematic procedures and numerical examples.
