What is formula for maximum load due to bending of a simply supported beam?
Wiki User
∙ 12y ago
The strength, S, of the beam is Mc/I where M = max moment to fail = PL/4 for load concentrated in the middle of the beam or WL/8 for uniformly distributed load.
Here P is the concentrated load, W = distributed load, c = distance to outer fiber from neutral axis and I the area moment of inertia of the beam. L = length
Solving for load maximum,
P = 4IS/Lc for concentrated center load
W = 8IS/Lc for distributed load

∙ 12y agoThis depends on the arrangement of a beam or column.
for a simply supported beam with a point load in the centre of the beam
Mmax = WL/4 and will occur at centre span
W is the load in kN
L is the span in m
Moment is given in kNm
for a uniformly distributed load w given in kN/m
Mmax = wL^2/8 and will occur at centre span.
Google will provide you with bending moment formulae and diagrams for more complex arrangements.

How will you know if it is a simply supported or a continuous slab?
a slab of a house suupported with RCC frame column & beam, What will be the bending moment in different spans. ER. J.S.DEORI
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
How do you work out the max bending moment for an i cross sectional beam supported at either side with a central force of 20kN?
It actually depends on the type of beam it is. If it is a cantilever, the formula would be PL/2 and for a simply supported beam it would be PL/4
What are the Bending moment diagram for simply supported beam with udl?
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
How are bridges supported?
They are supported by pillars are column's.
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.
What are the Bending moment diagram for simply supported beam loaded in its center?
zero
Is theory of simple bending applicable to simply supported beam?
Yes, as long as your beam is relatively slender (i.e. L/d greater than about 2)

Is their sand benders?
Sand Bending is a variation of Earth Bending, as sand is simply "little chunks of earth".
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 a simply supported slab?
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.
Explain Why curtailment of main steel is possible close to ends of a simply supported element?
Reinforcements is provided to resist moment and shear force, in a simply supported beam maximum moment at centre and its reduces towards (zero)support. so no 100% reinforcments at support required, so curtailment is possible (max 50%) at ends.
Why is the reinforcement bars place at bottom of the simple supported beam?
When a simply supported beam is subject to bending; the top of the beam will be subject to compression, and the bottom of the beam will be subject to tension (think about the bottom of the beam stretching as it bends i.e. tension). Concrete is strong in compression but weak in tension, so steel reinforcement is added to allow it to resist this tension and carry bending sufficiently. Note: bars are generally added to the compression side too but that's for another day.
