10 Questions
At what percentage of the total load do vertical cracks suddenly start appearing in axially loaded reinforced concrete columns?
Up to 80%
What is the primary reason for the failure of axially loaded tied columns?
Lack of lateral support provided by the cover
Why are columns designed with a much higher safety factor compared to beams?
Columns are more likely to experience sudden collapse
Why do perfect straight columns subjected to pure axial loading experience a brittle failure mode?
Lack of lateral support
What is a characteristic of the failure mode of axially loaded reinforced concrete columns?
Failure is brittle
What is the primary cause of failure in axially loaded tied columns?
Spalling of the concrete cover
At what point does cracking usually start to appear in axially loaded reinforced concrete columns?
Approximately 80% of the total load
Why are columns designed with a much higher safety factor than beams?
Due to potential for sudden failure
What type of failure mode is usually observed in axially loaded reinforced concrete columns?
Sudden failure with little warning
What factor contributes to the buckling of longitudinal bars in tied columns?
Lack of lateral support
Test your knowledge on the failure mechanisms of axially loaded tied columns in reinforced concrete structures. Learn about the brittle failure with little warning, spalling of concrete cover, and buckling of longitudinal bars.
