Example 1: 2D soil column subjected to earthquake base excitation

Example Provided by: Quan Gu (UCSD)

---

This example is taken as a 3-D three-story reinforced concrete frame structure with rigid diaphragm behavior at each floor, subjected to bidirectional earthquake base excitation with ground acceleration time histories taken as the two horizontal components of the 1978 Tabas earthquake.
