two-span continuous beam with both ends fixed and one intermediate support has a degree of indeterminacy equal to:
Which among the following option is an example for Determinate structure?
Simply supported beam
Fixed beam
Propped cantilever beam
Continuous beam
The degree of indeterminacy of a three-span continuous beam fixed at both ends is:
What is the main structural advantage of a continuous beam over a simply supported beam?
Easier construction
Lower maximum bending moments
No need for supports
Simple analysis
The degree of indeterminacy of a continuous beam depends primarily on:
Number of spans and type of supports
Cross-section only
Loading type only
Material property only
In practice, Clapeyron's theorem is most useful for:
Exact analysis of complex indeterminate structures
Approximate estimation of deflections
Quick determination of support moments in continuous beams
Analysis of plastic hinges
In Clapeyron's theorem, if both end supports are simply supported (i.e., M₁ = Mc = 0), the central support moment MB depends on:
Only loading type
Only span lengths
Both loading type and relative span lengths
Neither, it is always zero
If a continuous beam has n spans and is supported on rigid supports, the degree of indeterminacy is:
n-1
2n
n
n+1
Which of the following structures behaves similarly to a continuous beam?
Cantilever balcony
Simply supported roof truss
Suspension bridge cable.
Railway track on sleepers
Which of the following is an advantage of continuous beams over simply supported beams?
Larger mid-span deflections

Reduction in maximum bending moment and deflection due to continuity
Less redundancy in structure
In a two-span continuous beam with central load in one span only, the deflection in the unloaded span will be:
Zero
Downward (sagging)
Upward (hogging)
Same as loaded span
For a two-span continuous beam with equal spans under uniformly distributed load w,but with both ends fixed, the bending moment at the central support (from Clapeyron's theorem) is:

Never used in practice
Less economical
More economical in material usage
Clapeyron's theorem of three moments is applicable to:
Simply supported beams only.
Cantilever beams only
Continuous beams
Overhanging beams only
Clapeyron's theorem fails to give correct results if:
Beam has variable El in spans
Load is triangular
Supports are rigid
Beam has more than 3 spans
