I-beam
you will need that to calculate the strength and deflection of the beam, and also strength of the support itself
Well with a beam it allows the bridge to support the bridge
Rcc beam is supported between two support to carry the structure
the beam supportion
There is no way to answer this question without knowing 1) How thick and how wide the beams is, and 2) What shape the beam is: I-beam? H-beam? Tubular beam? Wide-flange beam?
Plinth beam is provided to 1. support the wall above it 2. act as tie beam for columns
A sleeper is a beam which the bottom is higher than the living area it is near. A support beam that has no connection to a finished area.
A supported beam has both ends of the beam resting on a support. A cantilever has a single support often hinged close to or at one end with the other end supported in another manner.
1.50 meter from the support is the max. safe length cantilever beam
Column, beam, support.
arch bridges can support more weight than beam bridges but for price i say beam won.
