What are the three 3 types of columns of architectural design?

Preface

 The System of Columns and shafts have been used in Construction since Ancient Egypt( Which lasted from about 3100BC until it was eventually absorbed in to the Roman Empire in 30 BC) Ancient Greece and Ancient Rome. In ultramodern day construction, Column- Beam- Slab System is been used in all superstructures with new technology, and construction accoutrements . Generally the cargo of the arbor is transferred to the columns or walls through the shafts, down to the foundation, and also to the supporting sumnsoil beneath.

Piller or columns

 What is a column in civil?

 A column can be defined as a perpendicular structural member designed to transmit a compressive cargo. A Column transmits the cargo from ceiling/ roof arbor and ray, including its own weight to the foundation. Hence it should be realized that the failure of a column results in the collapse of the entire structure. The design of a column should thus admit significance.

 In the ultramodern construction assiduity, Columns are substantially constructed by concrete; piecemeal from that accoutrements similar as Wood, Steel, Fibre- corroborated polymer, Cellular PVC, and Aluminium too are been used. The type of material is been decided on the scale, seacoast and operation of the construction.

 What is column and its type?

 TYPES OF COLUMNS

 Columns can be classified bases on its Shape, Slenderness rate, type of lading and Pattern of side underpinning.

 Bracket grounded on Slenderness rate

 Long Column or Slender( The length is lesser than the critical buckling length and it fails by buckling.)

 Short Column( The length is lower than the critical buckling length and it fails by shearing.)

 Intermediate Column

 BASED ON SHAPE

 Cube

 Forecourt

 indirect

 Polygon

 Grounded ON TYPE OF lading

 Axially loaded column

 Axial cargo andun-axial bending column

 Axial cargo and biaxial bending column

 Grounded ON PATTERN OF Side underpinning

 Constrained columns

 helical columns

 RCC COLUMNS( corroborated CONCRETE COLUMNS)

 A corroborated concrete column can be defined as a structural member with a sword frame( underpinning bars) composed of concrete that's been designed to carry compressive loads.

 Types of Columns in Building Construction

 Columns are classified grounded on the several conditions which include

 Grounded on Types of underpinning

 Grounded on Types of Loading

 Grounded on Slenderness rate

 Grounded on Shape

 Grounded on Construction Material

 Grounded on Types of underpinning

 1. Tied Column

 This type of column is generally construction from corroborated concrete. Longitudinal underpinning are confined within nearly spaced tie underpinning. It's estimated that 95 of all columns in structures are tied.

 2. helical Column

 helical column is also construction from corroborated concrete. In this type of column, longitudinal bars are confined within nearly spaced and continuously wound helical underpinning. helical underpinning give side restrains( Poisson’s effect) and detainments axial cargo failure( ductile).

 helical Column

 3. compound column

 When the longitudinal underpinning is in the form of structural sword section or pipe with or without longitudinal bars, it's called as a compound column. This type of column have high strength with fairly small cross section, in addition to exhibition good fire performance.

 4. Axially Loaded Column

 still, also it's nominated as axially loaded column, If perpendicular axial loads act on the center of graveness of the sampling of the column. Axially loaded column is rare in construction since coinciding perpendicular loads on the center of graveness of column cross section isn't practical. Interior column ofmulti-storey structures with symmetrical loads from bottom crossbeams from all sides is an illustration of this type of column.

 5. Column with Uniaxial Eccentric Loading

 When perpendicular loads don't coincide with center of graveness of column cross section, but rather act eccentrically moreover on X or Y axis of the column cross section, also it's called uniaxially eccentric lading column. Column with uniaxial lading are generally encountered in the case of columns strictly connected ray from one side only similar as edge columns.

 6. Column with Biaxial Eccentric Loading

 When perpendicular on the column isn't coincide with center of graveness of column cross section and doesn't act on either axis( X and Y axis), also the column is called biaxially eccentric loaded column. Columns with biaxial lading is common in corner columns with shafts strictly connected at right angles at the top of columns.

 Grounded on Slenderness rate Grounded on slenderness rate,( effective length/ least side dimension), columns are distributed as follow

. Short Column

 still, the column is called as the short column, If the rate effective length of the column to the least side dimension is lower than 12. A short column fails by crushing( pure contraction failure).

 Short column

 7. Long Column

 still, it's called as long column, If the rate effective length of the column to the least side dimension exceeds 12. A long column fails by bending or buckling.

 Grounded on Shape Shape of Reinforced Concrete Column

 8. Square or Blockish Column

 They're generally used in the construction of structures. It's much easier to construct and cast blockish or square columns than indirect bones

 because of ease of shuttering and to support it from collapsing due to pressure while the concrete is still in flowable form.

 Forecourt column

Combined columns

 9. indirect column

 They're especially designed columns, which are substantially used in piling and elevation of the structures.

 10. L- Shape Column

 Generally, L- shaped column is employed in the corners of the boundary wall and has analogous characteristics of a blockish or square column.

 L- shaped column

 11. T- Shape column

 It's employed grounded on design conditions of a structure. T- Shaped column is extensively used in the construction of islands.

 T- shaped column

 12. Shape of Steel Column

 There are different standard and erected up shape of sword columns which are shown in Fig. and Fig. Common shapes of sword columns include I, channel, equal angle, and T- shape.
