AB  - Structural computational models created by Architectural Engineers frequently show an overly simplified representation of the soil-structure interface. Structures are routinely modelled without considering the influence of the structure foundation and underlying soil resulting in misrepresentation of the actual response.
In order to expose students to the challenges of accurate foundation modeling, students were asked to determine the appropriate boundary conditions for three structures: 1) A campus structure with a braced frame lateral system founded on embedded concrete pillars. 2) An off-campus podium slab on concrete columns founded on grade beams. The slab carries an office building currently under construction. Students were invited by the engineer to explore the building dynamic characteristics. 3) A laboratory two-story moment frame bolted to a concrete floor through steel base plates.
The students predicted the structural response by computational models and hand calculations. They were encouraged to complete the hand calculations first to provide a baseline for the computational models. After predicting the response, the students conducted dynamic experiments to measure the actual response of the structures. Prior to any experimentation students were surveyed about their choice of boundary condition representing the influence of the structure foundation and soil. Once the structures were dynamically excited by the students, they discovered that the boundary conditions do have significant effect on the structural response. It was for example found on the braced frame structure that the fundamental mode shape and frequency were significantly affected by the foundation flexibility. A laterally fixed foundation model favored by the students provided poor representation of the actual response.
The opportunity to compare response predictions to dynamic experimentation results was well received by the students and led to improved learning.
