Structural analysis is the foundation of a structural engineer’s education, which generally includes topics ranging from basic statics to solving complex indeterminate structures. Most courses focus on theoretical approaches to solving and understanding problems with a large focus on determining internal forces, external reactions, and displacements. In many cases, courses also include concurrent discussion about deflected shapes and actual behavior compared to theoretical assumptions. Courses may also use pictures, videos, simulations, and small, table-top models to illustrate such behavior. However, students still struggle with understanding structural behavior and the effects of as-built versus theoretical connections. Such differences are difficult to convey simply using photos, videos, simulations, and small, table-top models. Students never have the opportunity to physically feel the differences and experience large-scale models that illustrate such behavior mainly due to cost, fabrication complexity, and material stiffness. The authors from University A and University B designed large-scale, lightweight models for in-class use that allow students to experience structural behavior and feel the differences between various types of as-built connections.
This paper provides a detailed overview of the design, fabrication, and implementation of four large-scale experiential learning modules for an undergraduate structural analysis course using lightweight and flexible fiberglass reinforced polymer (FRP) structural shapes. The first module focuses on the behavior of beam-to-column connections compared to theoretical assumptions; the second module focuses on load paths and tributary areas related to a typical floor system; the third module focuses on the deflected shapes of determinate and indeterminate beams; and the fourth module focuses on the behavior of a portal frame subjected to both vertical and horizontal loads with various support configurations. The four modules were used throughout the structural analysis course at University A and University B to illustrate structural behavior concurrent to the presentation of various structural analysis concepts.
