Consider the below preliminary design of a two-story moment frame. Determine whether

plane bending is about the strong axis, ?? = 50 ? and solve for elastic behavior.
Transcribed Image Text:The image depicts a structural diagram of a steel framework with dimensions and labels for each beam and column. The key elements of the diagram are as follows:
**Columns and Beams:**
1. **Columns:**
- Column AB: W18 x 35
- Column BC: W12 x 72
- Column CD: W18 x 35
2. **Beams:**
- Beam EI: W18 x 35
- Beam IJ: W18 x 40
- Beam JK: W18 x 40
- Beam KL: W18 x 40
- Beam EF: W12 x 50
- Beam FG: W18 x 50
- Beam GH: W12 x 50
**Dimensions:**
- The total horizontal span of the structure is divided into three sections: 20 feet, 30 feet, and 30 feet between the columns.
- The vertical height of the structure is 20 feet to the top beam and 15 feet to the intermediate beam above the ground level.
**Support:**
- The base of each column (A, B, C, D) is shown with fixed or pinned supports, indicating stability and load transfer to the foundation.
This structural diagram is a simplified representation commonly used in engineering to visualize steel framing for buildings or other structures, indicating the size and type of each component.
