Beams may be termed as simply supported beams when end condition do not carry any end moments from any continuity developed by connection. A beam is called continuous beam when it extends continuously across more than two supports. A fixed beam has its ends rigidly connected to other members, so that moments can be carried across the connection.

Which of the following statement is correct?a)beams are termed as fixe...
C) Beams are termed as fixed beams when ends are rigidly connected to other members.
Explanation:
A beam is a structural element that is used to support load and transfer it to the columns or walls. Beams can have different types of end conditions, which determine how the beam is supported and how it reacts to loads. The correct statement is option C, which states that beams are termed as fixed beams when ends are rigidly connected to other members.
Fixed beams have the following characteristics:
1. Rigid connection: In fixed beams, the ends of the beam are rigidly connected to other members, such as columns or walls. This rigid connection prevents any rotation or movement at the beam ends.
2. Fixed support: The rigid connection at the ends provides support to the beam, preventing it from rotating or translating horizontally. This support creates a higher level of restraint compared to other types of beams.
3. Moment transfer: Due to the fixed support at the ends, fixed beams can transfer moments between the beam and the supporting members. This means that the beam can carry moments at its ends, which result in bending moments and shear forces along the beam.
4. Stiffness: Fixed beams are stiffer compared to other types of beams, such as simply supported beams or continuous beams. The rigidity of the fixed support limits the deflection of the beam under load.
Fixed beams are commonly used in structures where a high level of support and rigidity is required. They are often used in buildings and bridges to support heavy loads and resist lateral forces, such as wind or seismic loads.
In contrast, simply supported beams have one end that is pinned or hinged, allowing rotation at the support, while the other end is supported on a roller or a pin, allowing vertical movement but preventing horizontal movement. Continuous beams, on the other hand, extend across more than two supports, allowing for the transfer of moments and shears at intermediate supports.
Overall, the correct statement is that beams are termed as fixed beams when ends are rigidly connected to other members, providing a high level of support and stiffness to the beam.
