This document discusses different types of beams and supports used in architectural structures. It begins by defining a beam as a structural element that primarily resists lateral loads through bending. It then describes five common types of beams: cantilever, simply supported, overhanging, fixed, and continuous beams. Next, it lists and defines three types of supports: roller, pinned, and fixed supports. Finally, it briefly mentions types of loading on beams.

REVIEW OF SIMPLE SUPPORTED STRUCTURES
 What is a Beam?
It is a structural element that primarily resists load applied
laterally to the beam’s axis, its mode of deflection is primarily by
bending.
The loads applied in a beam result in reaction forces at the
beam’s support points. The total effect of all forces acting on the
beam is to produce shear forces and bending moments within the
beams.

3. TYPES OF BEAMS
1. CANTILEVER BEAMS – A beam which is fixed at one end and free at the other
end.
2. SIMPLY SUPPORTED BEAMS – A beam supported or resting freely on the
supports at its both ends.

4. 3. OVERHANGING BEAMS – the end portion of the beam is extended beyond the
support.
4. FIXED BEAMS – a beam whose both ends are fixed or built-in walls.

5. 5. CONTINUOUS BEAMS – A beam which is provided more than two supports.

6. TYPES OF SUPPORTS
1. ROLLER SUPPORT - It is a support which is free to rotate and translate along
the surface on which they rest.
2. PINNED SUPPORT - It is a types of support which resists the horizontal and
vertical loads but is unable to resists the moment.
3. FIXED SUPPORT - It is a support which is capable of resisting all types of loads
i.e. horizontal, vertical as well as moments.
4. SIMPLE SUPPORT - The simple support is used where the structural member
has to rest on the external structure. These types of support are not used
widely in daily life. It is similar to the roller support.
