# Column And Types of Column In Building Construction

Today I have the topic of the column and the types of columns. types according to Reinforcement, types according to Loading, types according to slenderness ratio, types according to shape, and types according to Construction Material. this is the most crucial topic in civil engineering.Column And Types of Column In Building Construction With Detail

### what is the Column in Construction?

Basically, the construction field has a different part of the building like column beam footing, etc. column is the vertical member of a building which is used for all load of building transfer to base.

### Types of Columns in Building Construction

Different Types of Columns in Building Construction

Types according to Reinforcement,

Types according to slenderness ratio,

Types according to shape

Types according to Construction Material

### Tied Column

This type of column is sometimes constructed from concrete. Longitudinal reinforcement unit of measurement confined at intervals closely spaced tie reinforcement. it’s computable that ninety-fifth of all columns in buildings’ units of measurement is tied.

### Spiral Column

The Spiral column is in addition constructed from concrete. throughout this form of a column, longitudinal bars unit of measurement confined at intervals closely spaced and incessantly wound spiral reinforcement. Spiral reinforcement supplies lateral restrains (Poisson’s effect) and delays axial load failure (ductile).

### Composite column

When the longitudinal reinforcement is at intervals the sort of steel section or pipe with or whereas not longitudinal bars, it’s remarked as a composite column. this sort of column have high strength with fairly little cross-section, in addition, to exhibiting good fireside performance.

If vertical axial a whole bunch act on the center of gravity of the cross-sectional of the column, then it’s termed as an axially loaded column. The axially loaded column is rare in construction since coinciding vertical a whole bunch on the center of gravity of column cross-section is not wise. The Interior column of multi-story buildings with symmetrical a whole bunch of floor slabs from all sides is an associate example of this sort of column.

When vertical on the column is not coincide with the center of gravity of the column cross-section and does not act on either axis (X and Y axis), then the column is known as a biaxially eccentric loaded column. Columns with line loading are common in corner columns with beams stiffly connected at right angles at the best of columns.

### Short Column

If the quantitative relation effective length of the column to the tiniest quantity lateral dimension could be a smaller quantity than twelve, the column is known as as a result of the short column. a quick column fails by crushing (pure compression failure).

### Long Column

If the quantitative relation effective length of the column to the tiniest quantity lateral dimension exceeds twelve, it’s remarked as a long column. associate degree extended column fails by bending or buckling.

### Square or Rectangular Column

They are typically used within the development of buildings. it’s torrential easier to construct and solid rectangular or sq. columns than circular ones because of simple shuttering and to support it from collapsing thanks to pressure whereas the concrete continues to be in flowable kind.

### Circular column

They are specially designed columns, that unit of measurement for the most part used in columns and elevation of the buildings.

### L-Shape Column

Commonly, the fashioned column is utilized at intervals the corners of the boundary wall associate degreed has similar characteristics of a rectangular or sq. column.

### T-Shape column

It is used to support the vogue requirements of a structure. the fashioned column is widely used within the development of bridges.

### Sort of Steel Column

These units of measurement are all completely different customary and designed up sort of steel columns that unit of measurement Common shapes of steel columns embody I, channel, equal angle, and T-shape.

The usual sort of composite columns unit of measurement
Based on Construction Material styles of columns supported construction materials embody
concrete, steel, timber, Brick, Block, and Stone columns.
