Abstract:

Structural Concrete II in Civil Engineer Master’s Degree is a course dealing with prestressed, membrane and slabs of concrete. Teaching concrete slabs, a theoretical model to obtain forces and stress through an elastic and linear behavior of materials is assumed to simplify rational models. Once finished theoretical models, four full-scale concrete slabs (2.40x2.40m) are tested up to collapse. Peak loads reached in laboratory are 3-5 times larger than loads obtained through theoretical models. Experimental data collected from the instrumentation and attending test are strongly valuable for students to justify the great difference between the real peak load and the theoretical load. Learning outcomes become mainly promoting critical thinking to explain differences between theory and real experimental test in structural concrete, use of specific instrumentation in structural members and interpretation of experimental test. Students can explore a real full-scale structure in laboratory and must research reasons why the behavior is so different from simplified theoretical behavior.
