Chapter 16 -
Objectives
Course objective: Recognize that columns may fail at loads below their yield-point load.
Learning objectives:
- Recognize that a column may experience buckling and instability.
- Calculate the Euler buckling load for pin-ended columns.
- Calculate Euler buckling load for columns with various end conditions.
- Use the secant formula to calculate lateral deflection and maximum stress in eccentrically loaded columns.
- Calculate allowable load on practical (non-ideal) columns.
- Calculate the largest eccentric load that can be applied to a column.
