There are two types of structure they are load-bearing structure and framed structure. In this post, you will learn the difference between the load-bearing structure and framed structure in detail. So, I recommend you to read all content without skipping any paragraph.
Simply load-bearing structure is the load is taken by a wall and then directly transfer to the soil. whereas in framed structure the load is taken by beam, the o the column, and at last to the soil through footing or foundation of the structure.
Load Bearing Structure
- Almost all the walls are provided with a shallow or deep foundation.
- All load-bearing walls are taken deep into the subsoil for the foundation.
- Load-bearing walls are constructed of bricks or stones.
- The thickness of load-bearing walls, in any case, is not less than 200mm.
- A load-bearing wall when once constructed shall remain in position and should never be dismantled.
- Best suited for small residential houses, rural houses, and houses up to three stories.
- Plans for different floors remains the same as every wall on the upper floors must be a corresponding wall in continuation.
- It requires soil of good bearing capacity like rocks, sandy soil, gravelly soil, etc.
- Too many openings for doors, windows, ventilators, etc. are not permissible.
- Almost all the walls are load-bearing walls.
- All the walls rest on the plinth beam not provided with any footing of foundation.
- Only columns are taken deep into the subsoil and are provided with footings.
- Columns beam and slabs are constructed of R.C.C.
- Only exterior walls are of thickness 200 mm and all interior walls are of thickness 100mm.
- The walls of framed structure can be shifted at any place as they are lighter and not load-bearing.
- Best suited for multistoried and high rise buildings, commercial complexes, public buildings, etc.
- Planning for each floor is independent and free from whatever the planning of the lower floor.
- Even in the case of soil with poor bearing capacity, the pile may be driven until hard stratum is reached and R.C.C columns are constructed over them.
- There is no such restriction in framed structure.
- All the walls are partition walls or screen walls none of the walls is load-bearing.
Difference between load bearing structure and framed structure
|RCC Framed Structure
|Load Bearing Structure
|It is Mostly used form of construction.
|It is Rarely used form of construction.
|It is Simple to Construct.
|It is Cumbersome to construct.
|Walls are constructed after the frame is ready
|There are no Columns and beams
|Thickness of wall
|Thickness of wall remains same with increase in height
|Thickness of wall increase with increase in height.
|Length of wall
|There is no limitation on length of wall
|There is limitation to construct long walls at a stretch
|Flexibility in planning & design
|Position of walls can be changed whenever necessary Greater flexibility in planning & design
|Not possible to alter the position of walls after the construction No flexibility in panning & design
|It can be constructed on any type of soil
|It can be constructed on hard strata
|It has Good earthquake resisting power.
|It has poor earthquake resisting power.
|Walls are thinner hence more floor area is available for use
|Walls are thicker hence less floor area available for use
|It has Less excavation
|It has more excavation
|Less materials are required
|More materials are required
|Cement & steel quantity
|Consumes more cement & steel
|Consumes less cement & steel
|Less no. of labours as well as skilled labours are required
|More no. of labours as well as Skilled & unskilled labours are required
|Large span area are possible
|Large span area are not possible
|There is no restriction on height
|Height is limited & suitable for 2 to 3 stories only
|Speed of construction
|It can be constructed more rapidly.
|It is Slow & time consuming
|Flexibility in changing room dimension
|No possible to change room dimension
|Cantilever can be easily provided
|It is Difficult to provide cantilever & permitted up to short span only
|Does not provide additional enclosure
|Provides additional enclosure
|Life is reduced if not done properly
|Life is less affected with the technique of work
|No much increase in cost with increase in depth of foundation
|Foundation cost is more
|It is economically for multi-storey building
|It is economical up to 2storey only
|Load is transferred to the beam, then column and at last to the soil through footing.
|The load is transferred to the soil by wall bearing structure
