Design steps for a doubly reinforced beam section | IS 456: 2000
To start the design of doubly reinforced beam you should have an idea about this type of section. As the name implies, in this type of beam section, we are
reinforcement
Longitudinal bars detailing of a column section
Longitudinal reinforcement is provided in column to carry the applied axial load and bending moment along with concrete. Minimum longitudinal reinforcement It should be at least 0.8 percent of the
What is Development Length | Calculation as per IS:456
To give you an idea of the significance of development length we will do a simple demonstration. Ask your friend to hold a pen or pencil in closed fist and
When do we need doubly reinforced beams ?
As the name implies doubly reinforced beams means we are providing the reinforcement in both the zones. In the case of a beam the zone is basically compression and tension
Why do we provide transverse reinforcement in beams?
Transverse reinforcement in beams is provided mainly to resist the shear forces or forces which act in a direction perpendicular to the longitudinal direction of reinforced concrete beams. We follow
Modular ratio in RCC beam design
Let us start with the basic definition of modular ratio. It is the ratio of elasticity modulus of two different materials. For example, let the value of elasticity modulus of
