Concrete Plinth ǀ Types of Beams ǀ Plinth Foundation
A concrete plinth is a beam made from reinforced concrete that connects the wall and foundation. The load of the wall is distributed evenly over the foundation, preventing the cracks from the foundation to extend into the wall above the foundation when the foundation settles. Besides, concrete plinths are useful for supporting heavy loads by providing an elevated platform for the heavy loads or machinery to be able to raise above the floor. Moreover, concrete plinths are also used as a part of a structure to form a jacking point to perform maintenance in the future for heavy structures. For instance, it can be used for changing the steel bearings during the maintenance of a bridge deck.
Types of Beams
A beam is a horizontal structural element that resists lateral loads and supports the weight of the elements of a building structure, such as the floor, roof, and ceiling. It carries the vertical load and transfers the load to a column or a wall. There are several types of beams and they are characterized based on their means of support, size, shape, geometry, equilibrium conditions, construction methods, and construction materials used as a beam.
1. Cantilever Beam
This type of beam is built with only one end fixed to a vertical structure and free at another end which is exposed to vertical loads. A cantilever beam is widely used for a variety of construction purposes, such as in buildings, balconies, overhanging roofs, and bridges.
2. Simply Supported Beam
This type of beam has both its ends resting freely on the supports. The ends are fixed with one end supported by hinge support and another end supported by roller support. The roller support allows the beam to move horizontally.
3. Continuous Beam
A continuous beam has more than two supports across the length. The supports are continuous along the length and are not only limited to the ends. This type of beam has lesser deflection and lesser bending movement compared to a simply supported beam.
4. Overhanging Beam
Overhanging beam has the features of a cantilever beam and a simply supported beam combined. This beam has either one or both its ends overhang with roller supports between the ends of the beam. An example of an overhanging beam is a balcony extending from a frame structure.
5. Fixed Beam
A fixed beam is supported at both ends. The ends are fixed to a vertical structure where no movement is allowed across the beam and the vertical structures. This type of beam is normally used to control the deflection of the beam.
6. Timber Beam
A timber beam is usually used to support the weight of the floor, ceiling, and roof of a building structure made of timber materials. It is also used in the construction of wooden roof trusses. When given proper treatment and care, timber is a strong and durable material.
7. Steel Beam
A steel beam is a product of structural steel with the purpose to support heavy loads as it has the properties of being strong and durable. It can be used for a variety of construction purposes, such as roof trusses, buildings, bridges, etc.
8. Reinforced Concrete Beam
Concrete itself alone is strong in compression but weak in tension. Therefore, steel reinforcement is used to withstand the tensile force in the concrete beam. Thus, a reinforced concrete beam is a structural element that is designed to carry transverse external loads.
The I- beam is given its name because it is shaped like the alphabet ‘I’. It is also referred to as H-beam or universal beam. It is designed to support the structural members of different construction purposes as it is generally strong and functional. It has the ability to withstand a variety of loads without bucking.
T-beam is shaped like the alphabet ‘T’ and is formed when the slabs of the floors, roofs, decks, etc, are cast uniformly with the beams. The slab and the beam together resist the positive bending movement.
11. Statically Determinate Beam
Statically determinate beam refers to the reaction forces of a beam that can be calculated using only equilibrium equations. For a statically determinate beam, temperature variations do not induce stress to the beam and the bending moment is independent of the moment of inertia.
12. Statically Indeterminate Beam
If the reaction force of a beam cannot be determined using only equilibrium equations, and other methods are needed to solve the reaction forces, then the beam is statically indeterminate. Stresses can be induced by temperature variations or due to lack of fit. The bending moment at any section of the beam is also depending on the material property.
A plinth is described as the base or bottom support that supports another structure, such as a column or pillar. It can be either part of the foundation or a separated unit. A plinth level is a structure where a column is placed, forming the foundation of a building structure. It is a part of the building that is not the same as the foundation level but rises above the foundation level. The level raised is called the plinth level where the plinth beams are constructed. These plinth beams span across the columns and act as a tie. They are usually slightly higher than the ground level and withstands the wall loads constructed above them.
