What is the purpose of edge beam?
The purpose of the edge beam is to support the railing and the pavement, function as part of the drainage system and in the case it is integrated into the bridge deck it can serve to distribute concentrated loads.
What is the purpose of a cantilever beam?
The cantilever beam is a beam that is fixed at one end and set to be accessible at the other end and distributes the load back to the support where it is forced against a moment and shear stress. And cantilever beam allows the creation of a bay window, some bridges, and balconies.
Where do we provide reinforcement in cantilever beam?
In the cantilever beam, the top fibres above the neutral axis are subjected to tensile stresses. So the main reinforcement is provided above the neutral axis.
What is an edge beam in construction?
A Drop Edge Beam is the edge of a concrete slab that holds the fill under the slab and are usually used on blocks that require cut and fill to flatten the slope of the land.
How does cantilever beam relieve stress?
Here are five strategies to reduce deflection in a beam.
- Decrease the load.
- Shorten the span.
- Stiffen the beam.
- Add weight to the beam ends.
- Fix the supports.
Why reinforcement is provided in top of the cantilever beam?
A cantilever beam under the action of the structural load is subjected to moment and shear stresses. Hence during the design of cantilever beams, the main reinforcement is provided to the upper fiber of the concrete beam to withstand the tensile stress safely.
What are the advantages of a cantilever beam?
Cantilever beam is simple in constructions. It does not require a support on the opposite side. Cantilevered structure generates a negative bending moment which counteracts positive bending moment of back-spans. Cantilevered trusses use less material.
I believe an edge beam is the beam at the very end of the concrete slab that supports the edge of the slab. For example, if you had a rectangular concrete slab, the edge beams would be lining the perimeter of that slab. An edge beam with a cantilever slab would be when the slab actually extends out over…
What is a cantilever in construction?
A cantilever is a rigid structural member such as beam fixed at one end to a commonly vertical support from which it protrudes. It can also be constructed with trusses or slabs or metal girder. When subjected to a structural load, the cantilever carries the load to the support.
Can a cantilevered slab be supported on only one edge?
Sid Hazra has the right idea and the image in his answer is perfect. As you can see, the cantilevered slab (for example a balcony) is only supported on one edge. This slab has only a single beam carrying it, meaning it is completely non redundant.
