Bending Moments In A Portal Frame Manufacturer,Supplier and Exporter in India

Bending Moments In A Portal Frame (Product Code: SLE/EG/07) is a strain-gauged portal frame that lets students measure bending moments around a real frame and draw its bending moment diagram from test data. The frame is held between two fixing blocks and can take vertical, horizontal or combined loads, plus loads on moment arms that mimic cantilevered floors. A precision indicator records sway. The module is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, whose range of vocational training and university lab equipment covers structures, fluids and materials.

Key Details

Typical Use

Students first measure the frame section with the Vernier caliper and use textbook methods, such as moment distribution or the flexibility method, to predict bending moments at the gauge positions and the expected sway. They then apply the chosen load case and read the strains, converting each to a bending moment. Because the gauges sit at key points around the portal, the measured values can be joined up into a bending moment diagram and laid directly over the calculated one.

Running several load cases shows how the diagram changes shape: a vertical load on the beam, a horizontal load at eaves level, the two combined, and loads on the moment arms that represent floors projecting inside or outside the frame. Comparing sway with prediction completes the picture. This makes it a valuable piece of engineering educational equipment for building-frame analysis in civil and structural programmes.

Frequently Asked Questions

How is the bending moment measured?
Strain gauges at key points around the portal measure strain, from which the bending moment at each point is calculated.

What are the moment arms for?
Loads hung on moment arms on the vertical members simulate internal and external cantilever floors, adding a realistic load case.

Is a strain gauge amplifier needed?
Yes, the strain gauges connect through a strain gauge amplifier to the Structures Platform hub. Please contact us to confirm whether the amplifier is part of your supply.

Is the Vernier caliper included?
Yes, a Vernier caliper is included for measuring the cross-section.

What load range and frame dimensions apply?
Numerical specifications are not listed in our current description; ask us for the datasheet.

Are warranty and calibration papers provided?
Warranty is stated in the quotation. Calibration documentation for the sensors can be discussed with us before ordering.

Can you supply overseas universities?
Yes, we supply institutions across India and in international markets.
