Brief overview of Reinforcements for Slabs-on-Ground Crack Width Control

While going to create the design for slabs which are built up on the ground, give heed to the crack control factors. Given below, the brief explanation on Reinforcement details for slabs-on-ground.

The density and design of the slabs-on-ground are dependent on the cracks which are developed because of the outward loading. The computation of slab thickness is done on the basis of the assumptions of a slab that is unreinforced and uncracked.

For specific situations of slabs on ground, the steel reinforcement offers great solution. The properties of this process contain the following:

The limiting of cracks occurred because of shrinkage Use larger joint spacing that exceeds the unreinforced slabs Provision for moment capacity and strength for those areas may develop cracks The integration of reinforcement won’t avoid cracking. These elements allow for minimizing or managing the crack width developed by absolutely raising the frequency of cracks that is created.

A reinforcement design perfectly symmetrical and positioned can facilitate restraining the width of the crack and therefore the serviceability period of the slab remains unaffected.

Thickness Design Methods for Slabs-on-Ground Construction

Uncracked strength of the slab remains unaffected when there are more and more reinforcement in the slab design. The various thickness design methods like Pickett’s Analysis Method (PCA), WRI (Wire Reinforcement Institute) Design Method and COE methods are utilized for making the design of slabs on ground with reinforcement.

Reinforcement for Slabs-on ground for Crack Width Control Only

The crack width is controlled by reinforcement depending on the two factors like the joint spacing and the thickness of the slab. The crack width control can also be defined as a function of joint space and slab thickness.

A minimum steel ratio of 0.5% of the slab cross section is suggested to remove the saw cut of contraction joints.

While going to arrange the reinforcement, it is recommended to position the reinforcement bars adjacent to the surface of the slab top surface maintaining the least concrete coverage over the reinforcement.

Detailed guidelines on Bar Bending Schedule of Beam

This construction video is based on Beam Reinforcement Details. By watching this video, one will be familiar with Bar Bending Schedule of Beam with some easy to follow processes.

Reinforcement in beam

The role of reinforcement is to withstand tensile stresses because of bending and shear in beams for singly reinforced sections. But some factors like architectural reasons or basement floors can limit the depth of section. Therefore, the beam section is designed as doubly reinforced to withstand tensile and compressive stresses and delivered with reinforcement in compression face.

Bar Bending Schedule for RCC Beam

Bar bending schedule is used to make the reinforcement calculation toward reinforced concrete beam. It presents the details of reinforcement cutting length, type of bends and bend length.
