What is column head?

Column heads are used to increase the shear strength of slabs and to reduce the bending moment in the slab by reducing the effective span. The column head dimensions will be 90×90 cm and the depth of the head is 25 cm.

What is column head in construction?

A mushroom-like enlargement of reinforced concrete, at the upper end of a column, designed and built to act as an integral unit with the column and the floor slab above so as to increase the shearing resistance.

What is the purpose of drop panels?

Uses of drop panels : Drop panels increase the shear strength of flat slab floor. Drop panels increase flat slab’s negative moment capacity. Drop panels reduce deflection by stiffening the flat slabs.

What are drop panels in concrete?

Flat slab concrete floor system is similar to the flat plate system. The only exception is that the flat slab uses drop panels (thickened portions around the columns) to increase the nominal shear strength of the concrete at the critical section around the columns.

What is column head in flat slab?

For the column head case, the column head is defined similar to the drop panel (to avoid superimposing the column head over the slab, there must be holes created in the slab; there must be some other thicker slabs created inside these holes, that will act as the column head).

What is drop panel and column capital?

Drop panel is a thickened slab around column to gain shear capacity, and often to avoid the need for shear reinforcement. Column capital is a massive inverted truncate cone for circular columns, or truncate pyramid for rectangular, and square columns.

What is the difference between column capital and drop panel in a flat slab system?

What is drop panel in column?

Drop panels are the rectangular portion provided above the column and below the slab in order to restrict slab from getting sheared and undergo rupture. It represents increase in stability and efficient manner of load distribution to column. …

What is drop panel and column CAPital?

What is flat slab with drop panel and column head?

The flat slab is a two-way reinforced structural system that includes either drop panels or column capitals at columns to resist heavier loads and thus permit longer spans. – Partition walls can be placed anywhere. – Offers a variety of room layouts to the owner. – False ceilings can be omitted.

What is drop panel in flat slab?

Drop panels are the rectangular portion provided above the column and below the slab in order to restrict slab from getting sheared and undergo rupture. Drop panel increases the contact surface area between the column and slab, which will enable a better distribution of load from slab to column.

What is the use of drop panel in flat slab?

Uses of drop panels : Drop panels increase the shear strength of the flat slab floor (i.e it resists shear). Drop panels increase the flat slab’s negative moment capacity. Drop panels reduce deflection by stiffening the flat slabs.

What is a drop panel in construction?

Drop Panel is : A Projection below the slab used to reduce the amount of negative reinforcement over a column or the minimum required slab thickness, and to increase the slab shear strength. 8 clever moves when you have $1,000 in the bank.

What is the difference between a flat slab and drop panel?

In flat slabs, the columns are provided with enlarged heads called capitals or column heads. The thickness of slab over columns is also increased to support heavy loads and the thickened part of the slab is called drop panel.

What are the advantages of using DropDrop panel?

Drop panel increases the contact surface area between the column and slab, which will enable a better distribution of load from slab to column. Thus, it will reduce the chance of slab failure due to unbalanced moments.

What is the difference between column head and flat slab?

It is part of flat slab. It doesn’t support any other structural member. Column head is a bracket on top of column or an enlarged cross section of column at its top on which other structural member can rest. It provide additional base area (more than that of column cross sectional area) which serves as a base to other structural members.
