10 Questions
In which mode of failure does the entire cross section of a column experience compression with a small bending moment?
Point B
Which point represents a balanced loading condition in terms of axial load and moment?
Point D
If tension begins to develop on one side of the column due to increased eccentricity, which point represents this situation?
Point C
Which situation leads to the crushing of concrete with all reinforcing bars in compression due to large axial load and negligible moment?
None of the above
What type of failure occurs when a column has large axial load and small bending moment such that the entire cross section is in compression?
Failure by concrete crushing with bars in compression
What is the term used to describe the condition where the reinforcing bars on the tension side reach their yield stress at the same time the concrete on the opposite side reaches its maximum compression?
Balanced loading condition
