Most beams for buildings are bolted together and allow some rotation at the fittings, and are treated as simply supported beams. It is not question of better but of practical design. If rigid connections with fixed ends are desired, it will usually invove welding

They are supported by pillars are column's.
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. Links are provided to sites where more detailed information is available.
A simply supported beam is commonly used in structural engineering and construction for bridges, buildings, and various frameworks. Its design allows for easy support at both ends, making it ideal for spanning short distances while efficiently carrying loads. Applications include floor systems, roof trusses, and even in machinery where straightforward load transfer is required. This type of beam is favored for its simplicity in analysis and construction.
The size of rebar used in a reinforced cement concrete (RCC) beam typically depends on the design load, span, and structural requirements. For a simply supported beam of 17 feet, common rebar sizes range from #4 (1/2 inch diameter) to #6 (3/4 inch diameter) for main reinforcement, with additional smaller bars for stirrups. However, it is crucial to consult structural engineering guidelines or a structural engineer to determine the appropriate rebar size and spacing based on the specific loading conditions and design codes.

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.
The slabs that are supported only at end are called simply supported slabs i.e. there is no intermediate supports in the slab and there will be no support moment acting on the slab.

You have it backwards. Theories are supported by evidence. Evidence is not supported by theories, evidence is simply observed.
They are supported by pillars are column's.
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
No. A seismic wave can simply be though of as an "earthquake wave". Seismic waves originate in the tectonic plates of the Earth as they crash against each other, causing a vibration.

In air, the seismic waves(P-wave) are simply sound waves, and travel with the speed of sound (approx. 335 m/s).

b'coz in smply supported beam it has two fixed ends
