Hello,
Gantry Girders: Introduction
Gantry girders are used in the factories, where the loads are transferred from one place to another with the helps of cranes mounted on the bridges. Bridges across the yards are supported by the gantry girders with the help of the wheels and rails on the girders. Bridges can move along the gantry girder and more than one bridges can also be there on a gantry girder.
Gantry girders generally are composed of the rolled steel sections. They may be composed of more than one section, like channels and beams together.
To design a gantry girder, we have to find out the maximum bending moment which will occur on the gantry girder, due to external loads, and its own self weight.
As we know that absolute maximum bending moment for a simply supported girder will occur at the center, the central section are designed accordingly and the sections at the ends may be curtailed.
Curtailing the ends means cutting the section along the flanges, for making the design economic.
thanks for your kind visit!
