JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Pre-requisites

RCC Design and Analysis

Course Objectives:

• 1. To derive the differential equations for beam-columns
• 2. To understand the elastic buckling of bars and frames
• 3. To understand the Torsional Buckling
• 4. To analyze lateral buckling of beams and plate

Course Outcomes

After completion of the course, students should be able to

• 1. Apply the approximate methods based on energy to determine the stability of simple systems
• 2. Differentiate how the tangent modulus and double modulus theories of inelastic buckling led to the column paradox, thereby preventing further difficulties for a general theory of structures
• 3. Analyze elastic and in-elastic buckling of bars and frames
• 4. Analyze the beams for lateral torsional buckling
