SERVICEABILITY THEORY

BEYOND STRUCTURAL COLLAPSE.

Deflection is a serviceability limit state. While a beam may not collapse, excessive sagging causes partition cracking and user discomfort. IS 456 mandates limits to preserve architectural integrity and structural performance.

ENGINEERING CRITERIA.

L/250 Constraint

The standard limit for sagging below the casting level. For a 5m beam, this allows 20mm of total instantaneous deflection.

Concrete Grade vs Ec

Higher concrete grades increase the Elastic Modulus (Ec = 5000√fck), significantly reducing deflection for the same section size.

What is Beam Deflection Calculator?

Calculate instantaneous deflection of RCC and steel beams for various load cases and support conditions.

Technical Overview

Verify the serviceability of your structural members. This tool calculates the short-term and long-term deflection of beams under various loading conditions (UDL, Point Load) and compares them against the permissible limits specified in IS 456 (Span/250 or Span/350).

Common Questions

1
What is the allowable deflection limit?

As per IS 456, the final deflection of a beam should not exceed Span/250. Deflection after partition construction should not exceed Span/350 or 20mm, whichever is less.

2
How does creep affect deflection?

Long-term deflection is significantly higher than instantaneous deflection due to creep and shrinkage of concrete, typically accounted for using age-dependent modification factors.
