Question

The effective width '$b_f$; of flange of a continuous T-beam in a floor system is given by

$b_t=\frac{L_0}{6}+b_w+6D_f$

where $L_0$ represents the

• A. distance between points of contraflexure in a span
• B. effective span of beams
• C. clear span of beams
• D. spacing between beams

Answer 1

The correct option is A distance between points of contraflexure in a span

As per Clause 23.1.2. In effective width formula
for T-beam $L_0$ represents distance between points
of zero moment in beam.
