Column Failure Modes Under Axial Load
An axially loaded column can fail in several ways. Understanding these failure modes is crucial for structural design.
Failure Modes Explained
- Squashing (B): This occurs in short, stocky columns. The axial compressive stress reaches the material's yield strength, causing the column to shorten and fail by yielding. It's essentially a material failure under compression.
- Local Buckling (A): This involves the buckling of individual components of the column's cross-section (like flanges or webs) before the entire column buckles or yields. It typically happens in columns with slender cross-sectional elements.
- Joint Buckling (C): This refers to the buckling or instability of the connection point where the column meets other structural elements. While critical for overall structural stability, it's not a primary failure mode *of the column member itself* due to axial load in the same way squashing or local buckling are. The question focuses on the column's failure modes.
Correct Failure Modes
For an axially loaded column, the primary modes of failure related directly to the column member itself are:
- Squashing (B): Occurs when the axial load causes compressive stress exceeding the material's yield limit, especially in short columns.
- Local Buckling (A): Occurs when thin parts of the column's cross-section buckle individually under compression, typical for slender sections.
Joint buckling (C) is related to the stability of connections, not the inherent failure modes of the column under direct axial load.
Conclusion
Therefore, the correct failure modes for an axially loaded column from the options given are Squashing (B) and Local Buckling (A).
The correct answer includes options A and B only.
