What Are Planted  Column, Floating Column, Hanging Column, and Stub Column

What Are Planted Column, Floating Column, Hanging Column, and Stub Column (1)

Above all column Like Planted  Column, Floating Column, Hanging Column, and Stub Column are different name but all column is the same work

The floating column (Planted  Column, Hanging Column, and Stub Column) is nothing but a vertical member or element that rests on a beam but does not transfer the load directly to the foundation.

Generally, the columns rest on the foundation to transfer loads coming from slabs and beams, floating column acts as a point load on the beam and this beam transfers the load to the column below it, that beam is called a transfer beam.

The use of floating columns (Planted  Column, Hanging Column, and Stub Column) is intended for an architectural view, site conditions and as much as possible area on a plot within, permissible bye-laws.

Earthquake is a natural phenomenon in which disasters are mainly caused by damage to the building or the loss of other man-made structures.

Generally, the failure of the structures begins at the point of weakness. This weakness arises because of discontinuity in mass, discontinuity in load transferring path, Stiffness and irregular geometry.

What Is Planted Column?

Planted Column (1)

planted column is a vertical compression member that is supported on a non-axial bearing member such as slabs or beams to be able to answer the structural requirements without sacrificing interior and architectural needs.

Unfortunately, there are not many studies about the behaviour of planted columns and the supported beam.

What Is Floating Column?

Floating Column

The floating column is a vertical member which rest on a beam but does not transfer the load directly to the foundation.

The floating column acts as a point load on the beam and this beam transfers the load to the columns below it.

or

What Is Hanging Column?

Hanging-or-Floating (1)

The Hanging column is a vertical member which rest on a beam but does not transfer the load directly to the foundation.

The Hanging column acts as a point load on the beam and this beam transfers the load to the columns below it.

or

What Is Stub Column?

Stub Column

stub is a short element meant to be a connection to another structural element. It is either vertical or horizontal. A column supports to beams/girders that support slabs/flooring.

Why Need of Floating Column?

column is a vertical member which transfers the loads from beam to foundation whereas a floating column ( Planted  Column, Floating Column, Hanging Column, and Stub Column) is a vertical member which transfers the load from beam to another beam.

But a floating column ( Planted  Column, Floating Column, Hanging Column, and Stub Column), instead of transferring the load to foundation transfers the load on to the beam.

Why Need of Planted Column?

planted column is a vertical compression member that is supported on a non-axial bearing member such as slabs or beams to be able to answer the structural requirements without sacrificing interior and architecturaneeds.

or

Why Need of Hanging Column?

Hanging Columns

This is widely used in high storied buildings for both commercial and residential purpose. This helps to alter the plan of the top floors to our convenience.

The transfer beam which supports the Hanging column transfers the loads up to the foundation.

or

Why Need of Stub Column?

stub column is a column whose length is sufficiently small to prevent failure as a column, but long enough to contain the same residual stress pattern that exists in the column itself.

Hence, a stub column test is an important tool in the investigation of the strength of columns.

How are Floating Columns Incorporated in the structure?

Like in any structure, the load from the floors above is transferred to the column. The entire load is then transferred to the beam on which the floating column is going to rest. The floating column is designed as a regular column.

Floating Column and Earthquake

Floting Column (1)

As per IS:1893-2002 earthquake code India is classified into a different zone for which it specifies the seismic zone factor and it is very important to analyze & design the building for a seismic force to prevent damages occur due to earthquake.

The code of earthquake engineering has been designed with the aim that people get enough time to escape from the building, the building is less damaged and the building comes in faster use.

When earthquakes take place, the building passes at dynamic motion. The reason is that the building subjected to the inertial forces operating in the opposite direction of the acceleration of earthquake stimulation.

These inertia forces, called seismic loads, are usually handled as assuming forces are external Since the motion of earthquake varies with time and inertia forces vary with time & direction. Seismic loads are not stable in terms of time and space.

FAQ

Stub Column

Stub column is defined as a type of column that is not directly connected with footing, constructed over the beam or slab to transfer the load on the primary beam. Stub column is a non-structural type of column and the height of stub column is very less.

Floating Column

The floating column is a vertical member which rest on a beam but doesn’t transfer the load directly to the foundation. The floating column acts as a point load on the beam and this beam transfers the load to the columns below it.
