What is propped simply supported beam?

A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A propped cantilever beam is a beam which is fixed at one end ( no translation or rotation) and simply supported ( no translation) at the other end. A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A simply supported beam is a beam which is simply supported at both ends. A propped simply supported beam is a beam which is simply supported at both ends and simply supported at some other point such as at the center, to reduce deflection under load. Propped beams are statically indeterminate.


What is the advantage and disadvantages of fixed beams?

There isn't really an advantage of having a fixed beam vs. a simply supported beam, it depends on what application the beam is for. If one of the design criteria of the beam is that it be able to deflect from one end to another then you are going to want to use a fixed beam. For example such applications could include a diving bored. A simply supported beam differs from a fixed beam because the beam is supported at both ends. Thus when a simply supported beam is loaded, the deflection will occur throughout the beam, since the ends are confined and will remain as they were. Furthermore on a fixed beam, (the end that is fixed) will have restrictive forces and moments keeping the end from moving.


what is the deflection of a simple supported beam with point load?

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


Where does the maximum bending moment occur in a simply supported beam?

It depends on the loading conditions of the beam, it will generally occur close to the middle of the span.


How do you calculate reactions for a simply supported beam loaded with a uniformly distributed load?

For finding reactions for simply supported beam with uniformly distributed load, first we have to convert the u.d.l into a single point load. And then we have to consider it to be a simply supported beam with a point load and solve it. I think you know how to calculate the reactions for beam with point load.

What are the different between simply supported restrained beam and simply supported unrestrained beam?

because the deflection in simple suported beam is more due to the orestriction at the ends as the ends are freely supported by twoo supports

What is the simply supported beam?

A simply supported beam is just that - the most simple arrangement of the structure. The beam is supported at each end, and the load is distributed in some way along its length. There is more to the application of this than might first appear, but it's the starting point for analysis. What is the load on the beam going to be? If it's a floor joist, how much is the furniture going to weigh that is placed on it? What if someone wants to put a steel safe in the middle of the span of the beam under consideration? You get the picture. But it all stems from a beam supported at the ends and having to bear a load distributed in some way along its length. Simply-supported describes the constraints imposed on the beam by its foundations. A simply supported beam cannot have any translational displacements at its support points, but no restriction is placed on rotations at the supports.

What is a hinged beam?

It is a beam that is attached at aboundary that is free to rotate, like a hinge. It cannot develop a bending moment. It is often used to idealize a simply supported beam
