👉TYPES OF SLAB

⚡️PART 2

🌟5. Waffle Slabs Or Grid Slabs
Waffle slabs are lightweight slabs with hollow grid-like systems on their soffit. The hollow grid system reduces the self-weight of the slab without compromising its structural stability.

⏺The grids are spaced at equal intervals and they transfer the load from above to the beams. The space between the ribs is sometimes treated as a beam and reinforced to increase the flexural rigidity of the slab.
Due to their lightweight, they can span long distances with ease.

▶️The waffle slabs may have a grid system or a girder system where the bands of beam run throughout the slabs. The grids can be or any shape – square, rectangular, triangular etc..

🖱Application

⏺These types of slabs are used in public buildings, museums, airports, etc

🌟6. Ribbed Slab

▶️Ribbed slabs are very similar to waffle slabs but often mistaken for being the same.

▶️A ribbed slab has wide grids or bands of beams in the soffit of the beam whereas a waffle slab has deeper corresponding parts.
The ribbed slabs like waffle slabs are flexible, light in section, economical and can be constructed for longer spans. They have the same advantages and disadvantages as the waffle or grid slab.

🖱Applications

▶️Public buildings, museums, galleries.

🌟7. Hollow Deck Slab
Hollow deck slabs are special types of prefabricated concrete slabs that use the fundamentals of the stress developed in a section for the design.

▶️The concrete takes care of the compression while the steel takes care of the tension. There is no specific use for the concrete in the tension zone other than to provide a solid section.

▶️Taking this principle into account, the hollow deck slab does not provide concrete in the tension zone.

▶️It is provided with minimum concrete to hold the steel reinforcements in place. The hollow deck slab can be prestressed or non-prestressed.

🖱Applications

▶️Bridges, wall panels, multi-storey prefabricated buildings.

🌟8. Bubble Deck Slab

▶️Bubble deck slabs are hollow slabs where the concrete in the tension zone is replaced by recycled high-density polyethylene or HDPE plastic balls. Bubble deck slabs use the same principle as the hollow core slab.

▶️The concrete in the tension zone of a section has no structural importance.
The removal of that concrete will not affect the performance of the structure in resisting the loads acting on it.

▶️Bubble deck slabs can reduce the amount of concrete in a slab from 40% to 60%. This reduces the dead weight of the structure and also saves on costs.

🖱Application

▶️Bubble deck slabs are mostly used in public buildings, high rise buildings.

🌟9. Hardy Slab

▶️Hardy slabs are special types of slabs consisting of hardy bricks placed in a uniform fashion inside them. The hardy bricks are hollow blocks made of concrete. The depth of the hardy bricks is usually at least 200 mm.

⏺Therefore, the depth of the slab is increased.
The formworks are placed over which the hardy bricks are placed in rows with space between them.

⏺This space between the hardy blocks is treated as small beams. Reinforcements are placed within these ribs and concrete is poured and the slab is cast monolithically. It is mostly used in regions of high temperature.

🖱Applications

⏺Hospitals, office buildings, residential buildings, and public buildings.

🌟10. Dome Slab
▶️Dome slabs are hemispherical in shape and are used mostly to enhance the view of a structure. In ancient times, most structures were built in such a way that only compressive forces act on the structure.
⏺Before the invention of steel, there were no tensile materials known to man to resist tension. Therefore, the load was transferred through axial compression as in domes.
▶️In the modern era, the discovery of steel has led to thin sections of domes.

🖱Applications
⏺These concrete slabs are preferably used in monumental buildings, museums, meditation halls, galleries, and religious structures.

🌟11. Pitched Roof Slab
▶️The reinforced concrete pitched roofs are sloping slabs mostly preferred in high rainfall regions. The most common shape of a pitched roof is the triangular shape. Proper design must be made beforehand to ensure the smooth construction of the pitched roofs.

🖱Applications
▶️These types of concrete slabs are used in resorts, public buildings, and restaurants.

🌟12. Post-tensioned Slabs
▶️Prestressed slabs are commonly used in the construction of prefabricated buildings. Post-tensioned prestressed slabs have ducts that carry high-strength steel tendons in addition to conventional reinforcement.
The steel tendons are prestressed and anchored at the ends after the concrete slab has hardened. This is called post-tensioning. The post-tensioned slabs are mostly precast and are of various shapes.

🌟13. Pretensioned Slabs
▶️Pretensioned prestressed slabs are prestressed before the concrete hardens.

The high-strength tendons are pulled and the slab is cast. After the slab has sufficiently hardened, the prestressing strands are cut loose and the stress is transferred to the slab.
Pretensioned slabs are similar to post-tensioned slabs except for the prestressing part. They have the same advantages and disadvantages. However, post-tensioned slabs are widely used because of their ability to be cast in a shorter period of time.

🌟14. Prefabricated Slabs
▶️Prefabricated slabs are cast in the industry or site and transported to the place of construction. The prefabricated slabs can be of the following types:Pre-tensioned slabs
,Post-tensioned slabs,Hollow core slabs,Ribbed slabs

🖱Applications
▶️High-rise buildings for fast construction.

🌟15. Arched Slab
⏺Arched slabs are mostly found in bridges. Arches like domes, transfer the loads through axial compression. The arches are provided in the bridges to resist the wind loads acting on the bridge. In ancient times, arches were built in masonry, but modern developments are giving birth to reinforced curved arch slabs.

🖱Application
▶️These types of slabs are used in bridges, buildings, and tunnels.

🌟16. Cantilever Slab
▶️Cantilever slabs, as the name suggests, are fixed at one end and free at the other end.
▶️One great example of cantilever slabs is Balconies.
▶️The main reinforcement is provided in the span that is protruding outside. The secondary reinforcements are provided throughout the length of the slab. In RCC work, cantilever slabs should not be extended more than 4 feet.

🖱Applications
▶️Cantilever slabs are mostly used in residential buildings.

🌟17. Low Roof Slab
⏺Low roof slabs are also called lofts and are provided at the sill level of a building. The low roof slab is a cantilever slab that is provided above the doors and windows for storage purposes. The low roof slab is constructed during the construction of the lintel beam.

🖱Applications
▶️Residential buildings for storage.
🌟18. Sunken Slab
▶️Sunken slabs are the slabs that are provided below the bathrooms and washrooms. The level of the slab is reduced below the bathrooms so as to separate the grade between dry areas and wet areas. The sunken slabs shall also be used to provide cover for sewage pipes and fittings.
Sunken slabs are provided in buildings with identical floor plans.
▶️The level of the slab can either be increased or decreased based on the need.
Special care has to be taken to check water leakage in the pipes.

👉DO YOU KNOW ?
.
▶️Do you know that a doubly reinforced column base gives more rigidity, stability and the ability to transmit and distribute the load effectively to the soil beneath. The secondary reinforcement base provides resistance to punching stress as a result of an imposed load. Good morning peoples.
.
▶️Do you know that a weak footing of a structure can be strengthened through a means know as jacketing. However, the new footing base helps to establish a better platform for the effective distribution of imposed load substructurally without any form of deformation.

👉SHORT COLUMN VS LONG COLUMN
.
▶️SHORT COLUMN: Short column is defined as the column that contains very large lateral dimension with reference to its length or height is called as short column. Here, the proportion of effective length to its lateral dimension is under or equivalent to 12.
.
*The proportion of effective length of a short column to its radius of gyration remains under 40 or equivalent to 40.
.
*Bulking tendency is very poor. A column buckling analysis results in finding out the maximum load that a column can sustain prior to collapsing.
.
*The load bearing strength is high with reference to the long column of the similar cross-sectional area.
.
*The collapsing of short column occurs due to crushing.
:
▶️LONG COLUMN: Long column is defined as the column that contains small lateral dimension with reference to its length or height. Here, the proportion of effective length of column to its lowest lateral dimension surpasses 12.
.
*The proportion of effective length of a long column to its lowest radius of gyration surpasses 40.
.
*Column buckling easily occurs in long and slender column.
.
*The load bearing strength of a long column remains under with reference to short column with similar cross sectional area.
.
*The column normally collapses in buckling.
