## Why do we take factor of safety for concrete and steel ?

When we start with the design of a structure. It is very important to consider the structures safety and serviceability. As per IS 456: 2000, the structure should be capable

## What is neutral axis and what is the limiting depth ?

Let us consider an example where a beam is initially in unstressed position. Now when a uniform bending moment is applied along the length of beam , then the beam

## Designing singly reinforced beam section: An example

Before moving into the design procedure of a R.C.C beams you should be aware about the different types of beams available. There are basically seven types of beam depending upon

## Cracks in beams | Flexure crack and Shear crack

In any structural system crack arises because of stress in the structural system. Failure of a reinforced concrete beam in flexural shear will not result in a sudden failure. But

## 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

## Minimum and Maximum reinforcement in beams?

As we have already discussed in the previous port reinforced concrete beam is a composite section made of concrete and reinforcement. In this post you will get the answer of

## What is the fundamental assumption of flexural theory ?

In the process of analysis and design of a R.C.C sections, there are some few assumption which we use to make the process simple. Some basic assumptions are : Plane

## 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

## What is the difference between over reinforced beam and under reinforced beams ?

To start with you should first know what is a beam ? Beam is basically a structural member, constructed horizontally which resists the load applied on the it. The primary
