The portal frames used for measuring horizontal reaction are made from rectangular mild steel flats with a cross section of 10 mm thick and 40 mm wide, providing added rigidity. All components are in excellent condition. The ends of the frames can be fixed or hinged, depending on the requirements. Ball bearing rollers are installed at the end where the horizontal reaction is to be measured. These rollers move smoothly on a rolling platform. A chord is attached to the roller end and connected to a spring balance, which measures the horizontal reaction. The spring balance also captures data for measuring the slope and deflection. The two columns of the portal frame can be either clamped (fixed) or pivoted (hinged), depending on the needs of the experiment.

Experimental Objective

To study the behavior of a portal frame under different end conditions.

Specification

• The frame is designed with provisions to achieve different end conditions such as hinged, roller, and fixed.
• The size of the portal frame is 40 cm x 60 cm.
• The portal may also include provisions for a pulley arrangement and hook setup for horizontal loading at various positions.
• The apparatus will be supplied complete with a supporting stand and a set of weights.
• Electronic load cells, displacement cells, and an Electronic Control Unit (ECU) are provided with the apparatus.
• Software for digital calculations is included, making it easier for students to perform the measurements.
