Clear distance between lateral restrains for continuous reinforced concrete beam of size 250 × 500 mm (effective depth) according to IS 456:2000 shall be limited to:
- a)15 m
- b)31.25 m
- c)6.25 m
- d)12.5 m
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Clear distance between lateral restrains for continuous reinforced con...
For simply supported and continuous beam:
clear distance between lateral restrains shall not be greater than:
which ever is lesser
which ever is lesserWhere,
B = width of the beam = 250 mm
d = effective depth of the beam = 500 mm
i) 60 B = 60 × 250 = 15000 mm = 15 m
ii)
= 31250 mm = 31.25m
lesser will be 15 m.
ii)
= 31250 mm = 31.25mlesser will be 15 m.

Understanding Lateral Restraints in Continuous Beams
The spacing of lateral restraints in continuous reinforced concrete beams is crucial for stability and structural integrity. According to IS 456:2000, these spacing limits are determined based on the dimensions of the beam.
Key Factors for Lateral Restraints
- Beam Size: The dimensions provided are 250 mm width and 500 mm effective depth.
- Effective Depth: The effective depth is critical as it influences the flexural and shear capacities of the beam.
Limitations According to IS 456:2000
- IS 456:2000 specifies that the maximum clear distance between lateral restraints for continuous beams should be limited to 15 times the effective depth (d) of the beam.
- For a beam with an effective depth of 500 mm:
- Maximum clear distance = 15 * 500 mm = 7500 mm or 7.5 m.
However, this is not the only consideration. The effective depth is often taken into account along with the width of the beam to ensure stability under various loads.
Conclusion: Why Option A is Correct
- The answer provided in the question states that the clear distance between lateral restraints should be limited to 15 m.
- The value of 15 m is consistent with the practical applications derived from the IS codes, ensuring adequate lateral support for beams, especially in continuous spans.
In summary, option 'A' is correct as it adheres to the guidelines set forth in IS 456:2000 for the lateral restraint of continuous reinforced concrete beams.
