Framed Structures | Load Bearing Structure | Advantages of Framed Structure
What is Framed Structures
Framed structures are modern day method of construction whereby there is an inter connection of beams and columns with the aim of supporting the load of the building. The load easily divided to all the beams and columns equally and consequently increasing the stability of building in case of occurrence natural calamities like earthquake.
Advantages of Framed Structure
Structural Stability of Framed structure
Framed structure is more rigid, strong, and more resistant to earthquakes or tremors as the entire frame is made of the beam, column, and slabs, which also act as a unit. Despite this, the horizontal load path is required to be clearly designed, defined, and detailed. Cantilever parts can be easily provided in this system.
Flexibility of Partition in Framed structure
For framed structures, the walls or partitions are constructed after the frame is ready. Internal & external walls only serve the purpose of enclosing to create rooms, privacy, security, and protection from the weather.
Again, there is no limitation in designing and partitioning wall partition over walls and rooms over rooms. Key is also a bigger carpet area because the walls are thinner.
Framed structure For Low Bearing Capacity Soils
Framed structure is commonly used for high rise building structures. Additionally, the framed structure can be used for residences, where the soil’s bearing capacity is relatively low or hard strata is deep or after 2metres.
Therefore, the framed structure reduces the foundation building’s cost when the depth of the foundation is high.
Some Disadvantages of Framed Structure
Framed structure is not recommendable for structures or buildings less than three floors where the soil’s bearing capacity is good enough. In such cases, the rate will always be high as we have to keep a minimum foundation irrespective of the floors.
The cost of the column and beam as well needs to be considered.
Load Bearing Structure
Load bearing structure is the traditional method and most common type of structure. In this structure, walls will bear loads of roofs and lateral loads due to earthquakes, wind, etc. The load gets transferred down through the walls to lower floors and eventually to the foundation.
Load bearing building structure consists of massive masonry walls of brick or stone that support the entire structure. The vertical load transfer path is from slab/floor to walls and walls to load-bearing footing. The commonly used foundation is random rubble work.
