Struts and Columns
CHAPTER OBJECTIVES
Any strut or a column member in a machine, or a structure is designed on the basis of failure against buckling. Professor Euler initially provided a theory of buckling of such members. In this chapter, students will learn about:
- Theory of buckling developed by Euler for long columns.
- Euler considered the columns in the buckled state and then derived expressions for buckling loads. Professor. Rankine modified the Euler’s buckling load formula by combining the crushing load for short columns and Euler’s buckling load for long columns.
- Johnson’s parabolic formula for buckling load—an empirical formula.
- Secant formula providing information on maximum stress developed in a column section due to eccentric ...
