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 is a continuous concrete slab?
A continuous concrete slab is a type of structural element that is supported by beams or walls at multiple points along its length, rather than being simply supported at its ends. This design allows for the distribution of loads over a larger area, providing enhanced stability and strength. Continuous slabs are commonly used in floors and roofs of buildings, as they can span longer distances without intermediate supports. Their construction typically involves reinforcing steel bars to improve tensile strength and reduce cracking.

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 can calculate the rcc beam depth according to the span?
To calculate the depth of a reinforced concrete (RCC) beam based on its span, you can use the empirical formula: depth (d) = span length (L) / 12 to 16, depending on the loading conditions and beam type. For simply supported beams, a general rule of thumb is to use L/12 for lightly loaded beams and L/16 for heavily loaded ones. Always consider factors such as the material properties, loading conditions, and any applicable building codes for a more accurate design.

What are some examples of simply supported beams?
Simply supported beams are beams that rest on two supports at their ends and are free to rotate, allowing for bending under load. Common examples include a beam spanning between two columns in a building, a bridge supported at both ends, and a shelf resting on brackets. These beams experience shear and bending moments primarily at the mid-span due to applied loads. Additionally, simply supported beams are widely used in construction, such as in residential homes and industrial structures.

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 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 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
