What is the center of Stiffness?
AdityaBhandakkar
The centre point where whole mass is building concentrate called as centre of rigidity or centre of stiffness. In building, beams and columns carry all loads and transfer to foundation.

CB Sowmya
As per Is 456 - 2000, when using a helical reinforcement, we can consider an increase of 5% in the strength, Since helical reinforcements provide good ductility, it is suitable for earthquake prone regions where ductility is an important factor.

Distribution Steel The name itself defines the meaning of the word. Distribution bar n a reinforced concrete slab is placed usually at right angles to the main reinforcement bar, intended to spread a concentrated load on the slab and to prevent cracking and other types of failure.

Distribution Steel
The name itself defines the meaning of the word.
Distribution bar n a reinforced concrete slab is placed usually at right angles to the main reinforcement bar, intended to spread a concentrated load on the slab and to prevent cracking and other types of failure. It is also known as a Secondary bar.
The following point should keep in mind while understanding the distribution bar.
● The distribution bar is having a small diameter than the main bar.
● The distribution bar always place on the top of the main bar.
● Distribution bar placed in a longer span
Porpoises why we providing distribution steel in slab
● Distribution steel is provided to prevent the shrinkage stresses and temperature effects. Due to this, cracks are formed on the top of the slab; hence crack are neglected.
● To distribute the load equally to the main bars, hence decreasing the effect of point load on the slab.
● Distribution bars are also provided to Stability for the main bars, and they also help to keep the main bars in position.
See less●This steel distributes the localized loads, so the concentrated stresses are reduced & more even throughout the slab. The distribution reinforcement, in most cases, is designed for strength. But sometimes main porpoises to provided for other reasons like cracking, load distribution, etc.

What are the reasons of Building Collapse?
Vivek Patel
There is many reasons of collapse of building.

There is many reasons of collapse of building.
All of the defects are prevented by proper construction techniques and quality control, adequate structure design, and regular maintenance of buildings.
See lessWhich type of force acting on water tank wall ?
CB Sowmya
When the tank is on the ground Water pressure acts on the tank walls when the tank is full When the tank is below the ground, When the tank is full, the resultant of the soil and water pressure acts on the tank wall When the tank is empty, the soil pressure alone acts on the wall.
When the tank is on the ground
When the tank is below the ground,
- When the tank is full, the resultant of the soil and water pressure acts on the tank wall
- When the tank is empty, the soil pressure alone acts on the wall.

CB Sowmya
Poison's ratio is the ratio of lateral strain to longitudinal strain. It is the property of elasticity of a material. This means that, if a force is applied in a given direction, say along the axis of the member, then the poison's ratio is the ratio of the strain in the direction perpendicular to thRead more
Poison’s ratio is the ratio of lateral strain to longitudinal strain. It is the property of elasticity of a material.
This means that, if a force is applied in a given direction, say along the axis of the member, then the poison’s ratio is the ratio of the strain in the direction perpendicular to the axis and the strain along the axis.
The poison’s ratio of concrete is 0.1 to 0.2. Let’s take that it as 0.15. If a force is applied on a concrete specimen along its axis, then, for every 1 unit of deformation in the axis, 0.15 unit of deformation happens in the perpendicular direction.
Poison’s ratio is a measure of the elastic property of a material. There isn’t any direct relation between the strength of the material and the poison’s ratio.

A group of reinforced bars, parallelly set to each other to act as a unit should be limited four in a bundle used as reinforcement in reinforced concrete, enclosed by stirrups or ties.

A group of reinforced bars, parallelly set to each other to act as a unit should be limited four in a bundle used as reinforcement in reinforced concrete, enclosed by stirrups or ties. Bars greater than 32mm should not be bundled in beams.
The development length of every bar of bundled bars should be that for the individual bar, increased by 10 % for two bars in contact, 20 % for three bars in contact, and 33 % for four bars in contact.

The beam, which is reinforced from both zones i.e., compression and tension, that beam is said as Doubly Reinforced beam. It is usually given when the depth of the beam is constricted.

The beam, which is reinforced from both zones i.e., compression and tension, that beam is said as Doubly Reinforced beam. It is usually given when the depth of the beam is constricted. It is obviously not safe to provide a singly r/f beam with min depth resulting in failure due to insufficient resistance to oppose the bending moment.
Moment of resistance could not be increased by increasing the steel in the tension zone. Rather it can be increased by increasing the reinforcement, but it should not exceed 25% of the strained side. That’s why a doubly reinforced beam is provided to increase the moment of resistance of a beam having limited dimensions.
