| Load(kN) | The top lateral displacement of the column (mm) | YQKZ3 |
|---|---|---|
| 100.0 | +7.9 | A horizontal crack appeared on wing wall A and was 520.0 mm from the top surface of the bottom beam. |
| 141.1 | +12.0 | A slanted crack measuring 0.04 mm in width appeared on the concrete column and was 70.0 mm from the underside of the top beam. |
| +and-18.0 | Slanted cracks appeared on both wing walls A and B. | |
| 252.2 | -30.0 | The local concrete was crushed slightly at the bottom end of wing wall A. As the top lateral displacement increased, the width of the slanted cracks increased to a maximum of 2.0 mm, and the concrete was increasingly crushed at the bottom of the wing walls in response. |
