5 Questions
What typically initiates the failure of a tied column?
Spalling of the concrete cover
Why do axially loaded reinforced concrete columns exhibit brittle failure?
Due to lack of lateral support provided by the cover
At what approximate load percentage do vertical cracks start to appear in axially loaded columns?
80%
Why are columns designed with a higher safety factor than beams?
Columns are more prone to sudden, brittle failure
What is the typical outcome when perfect straight columns subjected to pure axial loading fail?
Brittle failure mode occurs
Explore the failure mechanisms of axially loaded tied columns in reinforced concrete structures, where the concrete cover spalling and buckling of longitudinal bars lead to a sudden collapse. Learn about the brittle failure nature with minimal warning signs and how vertical cracks appear before ultimate failure.
