What Does Reinforced Concrete (RC) Frame Mean In Construction?
Reinforced concrete (RC) frame is a type of construction that consists of horizontal elements (beams) and vertical elements (columns) connected by rigid joints.
The combination of concrete and reinforcing bars creates a material called reinforced concrete, which is used to increase the strength of the structure.
Reinforced concrete frames are commonly used in modern construction for buildings and bridges.
Reinforced concrete frames can be designed to resist both gravity and lateral loads through bending in beams and columns.
Earthquake resistance in RC frame structures can be enhanced by strengthening the components, such as columns and beams, or by using carbon fiber sheets to reinforce the walls.
Concrete frame structures are strong and economical, allowing for a variety of walling materials to be used with them, including masonry walls of brick, concrete block, or stone.
Additionally, any kind of cladding material can be used with concrete frame structures.
What Are The Advantages Of Reinforced Concrete Frame?
Reinforced concrete is a popular building material due to its strength, versatility, durability, fire resistance, and low maintenance costs.
It has a high compressive strength compared to other building materials and can also withstand a good amount of tensile stress due to the provided reinforcement.
Additionally, it is an economical material that can be molded into a nearly limitless range of shapes, making it ideal for precast structural components.
Reinforced concrete also requires less skilled labor for the erection of the structure than steel. However, reinforced concrete structures are heavier than others like steel, wood, and glass.
What Are The Disadvantages Of Reinforced Concrete Frame?
The main disadvantage of reinforced concrete frame structures is the lack of tensile strength.
Reinforced concrete is strong in compression but weak in tension, meaning that it cannot withstand large amounts of force in the form of stretching or pulling.
Additionally, reinforced concrete requires a lot of formwork, centering and shuttering to be fixed, which takes up a lot of space and requires skilled labor.
Furthermore, reinforced concrete takes time to attain its full strength, so structures cannot be used immediately after construction.
What Are The Types Of Reinforced Concrete Frame?
There are two main types of reinforced concrete frames: rigid frames and braced frames. Rigid frames are constructed on site and feature columns and beams that are connected by rigid joints.
Braced frames consist of columns and beams that are “pin” connected by braces to resist lateral stresses.
Both types of frames can be precast or cast on site, with precast concrete frames typically used for single-storey and low-rise structures.
Reinforced concrete frames also include slabs, which provide support for the frame’s horizontal components.
How To Design A Reinforced Concrete Frame?
Designing a reinforced concrete frame structure requires an understanding of the structural components and their connections, as well as the materials used in construction.
The applied lateral wind loads must be calculated based on the provisions of American Society of Civil Engineers.
To resist progressive collapse, design methods such as using shear walls to withstand horizontal loads, utilizing floor and beam’s catenary effect, dividing the structure into parts, and adding additional reinforcement should be considered.
Additionally, standards from other countries can be used for reference when designing a reinforced concrete frame structure to resist progressive collapse.
