HARDWARE
TecQuipment's Frame Deflections and Reactions hardware enables students to examine the horizontal reactions, fixing moments and direction of sway of two rectangular portal frames subjected to vertical loading.
One of a range of Structures teaching products, the Frame Deflections and Reactions experiment hardware includes load cells which monitor the moment at one end of the frames and the horizontal reaction at the other. Students use the results of moments and reactions to plot bending moment diagrams. They compare the bending moment diagrams, and the direction and causes of sway, to theoretical calculations. A digital deflection indicator measures sway. Both portals have the same overall dimensions. However, one portal has a constant second moment of area, while the other has one leg with a lower second moment of area.
The Frame Deflections and Reactions apparatus includes two load cells, leads to connect the load cells to a Digital Force Display (STR1a), weight hangers and weights, a rule, a lecturer guide and a student guide.

VIRTUAL EXPERIMENTS
The Frame Deflections and Reactions Virtual Experiments Software enables computer simulation of experiments working with or without the Structures teaching hardware. As well as all the experiments possible with the hardware, the software extends investigations further. It enables study of the relationship between the stiffness and stability of a structure and how it transfers its load into its footings.
During experiments, the software displays a force diagram and a bending moment diagram. Students can visualise, tabulate and graph data, reducing the time required for students to obtain, process and present results. This allows students to realistically, efficiently and conveniently investigate and compare the properties of a wide selection of frame deflections and reactions under varying applied loads.
The Virtual Experiments Software is available in a variety of multi-user and networked options, as well as single-user format.
