• Analysis and design of axially loaded bolted and welded connections.

• Eccentric connections (bracket connections) in bolted and welded joints.

Chapter 3: Design of Tension Members (4 hours)

• Types of tension members and net sectional area calculations (deductions for bolt holes, staggered pitches).

• Design concepts and strength evaluations (yielding, rupture, and block shear failure) using LSM.

Chapter 4: Design of Compression Members (7 hours)

• Behavior of compressive members, effective length, and buckling classes.

• Design of axially loaded single and built-up compression members (struts and columns).

• Detailing requirements for lacing and battening systems.

Chapter 5: Design of Column Bases (4 hours)
