It all depends on the dimensions of the steel beam
the beam gets bend if the load is more then the resisting force of the beam and if the resisting force is more then the load it doesn't bends.
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
The moment of a beam is twice that for central load vs uniform load for a simple support beam; hence it needs twice the section modulus for sizing; for fixed ends the moment is 50% higher for central load vs uniform load
Hi, I am only an undergrad civil engineer so feel free to correct me if I am wrong, but I will try to help! Say we are dealing here with a steel beam, spanning across a ceiling, and the load applied to it is the floor above. Let's presume it is supporting 2 loads, the concrete slab above it (dead load) and the service load (live load), i.e. people walking over the floor and hence varying. We need to estimate the area of floor the beam is supporting, so obviously this will be in m^2, and we also need to depth. We also need the characteristic service load for our type of building, and this can be found in a book such as the Metric Handbook (a must have for engineers!!) We then take the total area value to British Standards tables, which will give us a self weight of the concrete for a certain depth and a certain characteristic service load. It will also tell us the effective span of the floor. We then add together the dead load and live load, for the total load on the beam, so: applied load = (total area x concrete self weight) + (total area x characteristic service load) This should give you quite a large value with real buildings. UDLs are measured in N/m or kN/m, and so finally we just need to divide the total load by the span of the beam in metres. Also, not all of the load will be on the beam, some will be applied to the supporting structures, so you can assume that only somewhere around half of the final load is the UDL over the span of the beam. Hope this helps, Luke

when the load is applied in the beam then deflection takes place. the nature of the deflection depends on the support provided on it
the beam gets bend if the load is more then the resisting force of the beam and if the resisting force is more then the load it doesn't bends.

The beam will deflect in the direction of the load This is Hooke's law, which states that load is proportional to deflection
The neutral layer is a beam that supports a load is in the region where there is neither stretching nor compression.
it will depend upon the load and moment applied on the beam.

Deflection of simply supported beam is given by P*l^3/(48E) Where P= point load at centre of beam l= length of beam E= Modules of elasticity
i dont no
