Question
**Problem 30** An A992 W21×111 is used as a column in a building to support a dead load of 120 kips and a live load of 300 kips. The column effective length is 22 ft for the y-axis and 33 ft for the x-axis. Determine whether the column will support the load by (a) LRFD and (b) ASD. **Explanation:** - **A992 W21×111**: This refers to a structural steel wide-flange shape. The numbers denote its nominal size and weight. - **Dead Load**: Constant, permanent load; 120 kips in this problem. - **Live Load**: Temporary or changing load; 300 kips here. - **Effective Lengths**: - 22 ft for the y-axis - 33 ft for the x-axis **Objective**: Analyze if the column can support the specified loads using: - **Load and Resistance Factor Design (LRFD)** - **Allowable Stress Design (ASD)** No graphs or diagrams are included with this problem.
