The two most common structural systems used in building construction are load-bearing structures and framed structures. In load-bearing structures the walls are designed to carry the weight of the building, transferring it directly to the earth. In contrast, a framed structure is a type of building design where the load is carried by an external frame or skeleton. The external frame of a framed structure is made up of columns and beams that are connected together to form a grid-like structure. The walls of a framed structure are typically non-load bearing, while the load is distributed from the slab to the beams, then from the beams to the columns, and finally to the earth through the footings of the structure.
What is a Load-Bearing structure?
A load-bearing structure is a type of structure where the load of the building is carried by the walls themselves. In a load-bearing structure, the walls are typically made of masonry materials such as brick or stone, and they are designed to support the weight of the building. The floors and roof of a load-bearing structure are typically supported by the walls, rather than by an external frame.
One of the main advantages of a load-bearing structure is that it is relatively simple to design and construct. Because the load is carried directly by the walls, there is no need for an external frame or skeleton. This can make load-bearing structures more cost-effective to build, particularly in cases where the walls are constructed using locally available materials.
However, load-bearing structures are generally less flexible than framed structures, as the walls are integral to the stability of the building. It can be more difficult to add or remove walls or make changes to the layout of a load-bearing structure, as this can affect the overall stability of the building.
Load-bearing structures are commonly used in a variety of applications, including residential buildings, commercial buildings, and public buildings. They are particularly well-suited for smaller buildings or for buildings with simple layouts, as the load-carrying capacity of the walls can be easily calculated and designed for.
What is a Framed Structure?
A framed structure is a type of building design where the load of the building is carried by an external frame or skeleton. The external frame is made up of columns and beams, which are connected together to form a grid-like structure. The walls of a framed structure are typically non-load bearing, meaning they do not carry any of the weight of the building. Instead, they are used to enclose the space within the building and provide separation between different areas.
One of the main advantages of a framed structure is that it is more flexible and adaptable than a load-bearing structure. Because the load is carried by the external frame, the walls of a framed structure can be moved or modified without affecting the overall stability of the building. This makes it easier to add or remove walls, or to make changes to the layout of a building.
Framed structures are commonly used in a variety of applications, including residential buildings, commercial buildings, and public buildings. They are particularly well-suited for larger buildings or for buildings with more complex layouts, as the external frame allows for greater flexibility in the design and arrangement of the space.
