Is simply supported beam better than fixed for seismic design?
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
What are the types of beams in an aircraft?
cantilever beam,contineous beam,fixed beam,simply supported beam
What is the beam bridge weakness?
One of the weaknesses is that because of its design of two beams supported by varied types of supports on either end, it usually cannot be very long, although there are some exceptions.
How much brick support do you need for an I beam?
Brick does not support weight. I beams are normally supported by square tubing columns or pipes.
What are the materials needed to make a beam bridge?
Beam bridges are the most simple of structural forms being supported by an abutment at each end of the bridge deck. No moments are transferred throughout the support hence their structural type is known as simply supported.The simplest beam bridge could be a slab of stone, or a plank of wood laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete used can either be reinforced, prestressed or post-tensioned.Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders. They could be half-through, or braced across the top to create a through bridge. A footbridge using beams over a stream in Dordogne, FranceBecause no moments are transferred, thrust, as from an arch bridge, cannot be accommodated, so leading to innovative designs, such as lenticular trusses & bow string arches, which contain the horizontal forces within the superstructure.Beam bridges are not limited to a single span. Some viaducts such as the Feiyunjiang Bridge in China have multiple simply supported spans supported by piers. This is opposed to viaducts using continuous spans over the piers.Beam bridges are often only used for relatively short distances because, unlike truss bridges, they have no built in supports. The only supports are provided by piers.

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 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.
Where do stresses occur in a loaded beam?
Stress occur everywhere in the beam. Maximum occur at mid span and at support of simply supported beams and cantilever beams respectively - M. Velsamy, Mobile 9884585625
Point of inflection in continuous beams?
point of zero moment

What is the Difference between flat slabs and solid slab?
Flat slabs are the ones with or without drop panels supported by columns without beams.... whereas the solid slabs are the ones supported by beams and columns and constructed monolithically
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.

How is a continuous span related to a beam bridge?
It is like more beams and foundations introduced into the structure.
