STR14 - Experiment

CURVED BARS AND DAVITS

An experimental apparatus to allow students to investigate the relationships between load horizontal deflection, vertical deflection and stability in commonly used curved structures and davits and to compare the results with theoretical values.

The experiment hardware fits onto a Structures Test Frame (STR1, available separately). Included are four different structures. Students attach one of the structures in front of the hardware module, directly onto the test frame. They then apply loads to the structure using masses on hangers. Two digital deflection indicators, set at 90 degrees to each other on the backboard, contact the structure and so measure horizontal and vertical deflection. The digital deflection indicators are on a magnetic base so students can move them to anywhere on the backboard. 

As students load a structure they note the horizontal and vertical deflections, thus investigating the structure behaviour. They then compare this behaviour with theoretical predictions. 

The lecturer guide provides details of the equipment including sample experiment results. The student guide describes how to use the equipment and gives experiment procedures. 

For extra ‘virtual’ experiments, TecQuipment can supply the optional TecQuipment Structures Software (STRS), for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware. They also extend the choice of tests beyond that available using only the hardware, for example: higher loads, uniform loads or different test specimens. This extends the student’s learning experience. 

For automatic data acquisition of your experiment results, TecQuipment can supply the optional Automatic Data Acquisition Unit (STR2000). Supplied as standard with the STR2000 is TecQuipment’s Structures Software that displays and logs your experiment results and gives the extra virtual experiments.
