Reinforced Concrete Design

Lecture 3

Dr. Nader Okasha


Design of Beams For Flexure


Design of Beams For Flexure


Design of Beams For Flexure

The main two objectives of design is to attain the required strength and ductility.

Design moment strength (also known as moment resistance)

Internal ultimate moment


Design of Beams For Flexure

The beam is a structural member used to support the internal moments and shears

C = T

M = C*(jd)

= T*(jd)


Stress – strain distribution across beam depth


Design of Beams For Flexure

The equivalent rectangular concrete stress distribution has what is known as a b1 coefficient which is proportional to the average stress distribution.


Design of Beams For Flexure

Setup of equilibrium.
