Which of the following them is also known as multi span beam?
Cantilever beam
Simply supported beam
Fixed beam
Continuous beam
Continuous beam
A continuous beam is a structural member that rests on more than two supports, allowing it to span across multiple bays or segments. Because it extends over intermediate supports, it is commonly referred to as a multi-span beam.

M=8wL2тАЛ тАФ Bending moment for a single span (reference)
3M Theorem тАФ Clapeyron's theorem used to solve continuous beam moments
In a continuous beam, the bending moment and shear force are distributed across multiple spans, which reduces the peak positive bending moment compared to simply supported beams of the same span. The continuity at the interior supports induces negative moments, leading to a more efficient redistribution of internal stresses throughout the structure.
A continuous beam is a statically indeterminate structure.
Internal support continuity results in negative bending moments at the supports.
It provides higher stiffness and lower deflection compared to equivalent simply supported spans.
Greater structural economy due to moment redistribution.
Reduced deflection under load.
Increased overall structural rigidity.
Sensitive to support settlements causing stress changes.
Complexity in analysis (statically indeterminate).
Requires careful consideration of temperature stresses.
Bridge decks spanning multiple piers.
Floor systems in multi-story buildings.
Long corridor lintels.
Simply supported beams are statically determinate, whereas continuous beams require compatibility equations to solve.
Option A (Cantilever) is supported at only one end. Option B (Simply supported) has only two supports. Option C (Fixed) has restrained rotations at the ends.
D is correct тАФ A continuous beam is defined as a beam supported at more than two points, spanning across multiple intervals.
Always identify the number of supports; if supports > 2 for a horizontal member, it is almost certainly a continuous beam in structural exams.
