Girders  Meaning

A girder is a major support beam used in building and construction. A girder is the main horizontal support of the structure, which supports the smaller beams. They often have an I-beam cross-section composed of two load-bearing flanges separated by a stabilizing web. Girders may also have Z shape, box shape, or other forms or shapes. Girders are commonly used to build bridges, railway bridges.

Steel Girders

Steel girders are a type of steel beams  mainly  horizontal supports of a structure which support the smaller beams. It is good to not that all girders are types of  beams but all beams are not girders. The  beams and steel girders differ from each other in various aspects  but large beams are known as girders.

Girders in Bridges

A girder bridge is a  type of bridge that uses girders beams as the  way of supporting its deck. The types of beams commonly used  in making girder bridges are usually either box girder beams that are made of steel or concrete and shaped like an open box or I-beam girders, so called because their shape is reminiscent of a capital Roman letter I.


Difference Between Girders and Beams (Girders Vs Beams)

Basics Difference Between Beams and Girders

Beams are the main part of the structural framing system designed to carry any structure’s distributed load. These beams are the very common designed types of shape to resist load, and its primary mode of deflection is bending.

Girder is a kind of beam that supports different smaller beams due to performing as the main horizontal support of a structure. Unlike beams, girders are designed to assist good-sized concentrated load inclusive of columns or beam reactions. The load-bearing capability of a girder is a lot more than the beams. It supports the vertical weight of the beams.


Size Difference Between Beams and Girders

Another distinction between the girder and the beam is the size of each. In construction firms, large beams are known as the girder. There isn’t any strict length, width, or weight that determines if it is a beam or girder. Instead, the builders decide in step with how the type is used. When the components are smaller in size, it is a beam.

Also, all girders are beams as they are the primary horizontal support systems for smaller beams. If the builder has used the type to support all other smaller beams, it’s far known as a girder. But there are no strict guidelines in the National Building Code concerning the girder’s size to distinguish it from the beam.

Functionality Difference Between Beams and Girders

Both the components serve to withstand the forces of bending. Beams typically have the I-formed cross-sections composed of load-bearing flanges and power for stabilization. Beams help the buildings’ structural integrity and can be found in foundations, partitions, ceilings, roofs, and decks.

Girder is type that support the beams and acts as the main horizontal support of the shape. Like beams, girders typically have an equal I-form design. They might also tackle a field or Z-shape in addition to other forms of designs. Since girders specifically support smaller beams, they are used to construct the bridges and flyovers because they may be able to bear extraordinarily heavy loads.

Type Difference Between Beams and Girders

Beams are categorized into numerous different types. Based on the type of support that the beam presents, they may be categorized into – simply supported, fixed, continuous, cantilever, and trussed beams. They are also categorized on the geometrical issue as the curved, straight, and tapered beam. In addition, beams are also divided into I-beams, T-beams, and C-beams.

A girder is normally used to refer to a metallic beam. The most commonplace girder utilized in any structural metal creation task is I-beams. Even box girders are particularly used inside the construction of accelerated bridges and roadway flyovers.

Box girders are made from steel webs joined collectively at the pinnacle and the bottom by means of the flanges. This creates a closed cell that provides proper torsional stiffness and exceptional strength required for the curved bridges etc.

Load-Bearing Capacity Difference Between Beams and Girders

Beams can carry large weight but, when you compare it with the girders, the capability is tons lesser in terms of the component’s structural design and capability stage. Beams can’t support the identical weight that the girders can carry.

Girders are made to carry dynamic and rolling loads. Therefore, many builders choose girders for structural steel building projects wherein the loads are not very constant.

When it comes to carrying the dynamic load, it refers to the exert varying amounts of pressure on a structure. They are contrasted with static loads, accordingly exerting the identical amount of pressure at all times. Therefore, you want a special sort of beam to resist the dynamic load with consistent and unfailing strength potential that only girders can provide.

Jobs Difference Between Beams and Girders

A beam is a secondary beam or stiffener. Its foremost activity is to switch the load or weight to girders. Beams bend to deal with shear stresses.

Girder is a primary beam. Its main activity is to transfer the loads to the columns upon which it rests. Girders are stiffer to support the small beams. Stiffeners support the plating, girders support the stiffeners, or different girders.

Fabrication Difference Between Beams and Girders

During the beam’s designing level, the fabricators have to consider the necessities, which include protecting the shape and transferring the load to the girder. Custom metal beam fabrication is an effective and value-effective way to ensure you get the exact horizontal support structure you require for your structural metal construction metallic Project.

On the other hand, fabricators of girders cautiously keep in mind the necessities, including the erection of the girder, stability, deck placement series, plate sizing, welded connections, and flange sizing.

Girder fabrication may cost greater than beam fabrication. For girders, you need a crew of qualified structural metallic fabricators to fulfill the girder’s commercial fabrication project.
