Portal Frame Apparatus

The instruction manual outlines the use of a portal frame apparatus designed to study its behavior under various load conditions. It details the apparatus specifications, including dimensions and material properties, as well as the methodology for measuring horizontal deflection under different loading scenarios. Results from loading tests are to be analyzed by plotting graphs of deflection versus load and drawing best-fit curves.

APPARATUS

Portal frame is made up of M.S. plate of rectangular section . Frame is provided with

a provision to achieve different end conditions viz. hinged, roller . Portal is also

having a provision for pulley arrangement and hook arrangement for horizontal

loading at different positions.
