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
|S.N||RCC Framed Structure||Load Bearing Structure|
|Uses||It is Mostly used form of construction.||It is Rarely used form of construction.|
|Construction||It is Simple to Construct.||It is Cumbersome to construct.|
|Wall construction||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|
|Soil condition||It can be constructed on any type of soil||It can be constructed on hard strata|
|Earthquake resistance||It has Good earthquake resisting power.||It has poor earthquake resisting power.|
|Floor area||Walls are thinner hence more floor area is available for use||Walls are thicker hence less floor area available for use|
|Excavation||It has Less excavation||It has more excavation|
|Material requirement||Less materials are required||More materials are required|
|Cement & steel quantity||Consumes more cement & steel||Consumes less cement & steel|
|Labour requirement||Less no. of labours as well as skilled labours are required||More no. of labours as well as Skilled & unskilled labours are required|
|Span area||Large span area are possible||Large span area are not possible|
|Height||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|
|Room dimension||Flexibility in changing room dimension||No possible to change room dimension|
|Cantilever element||Cantilever can be easily provided||It is Difficult to provide cantilever & permitted up to short span only|
|Additional Enclosure||Does not provide additional enclosure||Provides additional enclosure|
|Life||Life is reduced if not done properly||Life is less affected with the technique of work|
|Foundation cost||No much increase in cost with increase in depth of foundation||Foundation cost is more|
|Cost||It is economically for multi-storey building||It is economical up to 2storey only|
|Load transfer||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|
