Introduction to Design of RCC Structures

RCC structures

RCC (Reinforced Cement Concrete) is a construction technology which evolved with the evolution of different structural materials in the 18th century during the Industrial Revolution.

Industrial Revolution brought in new technology which helped in the manufacture of various materials. The Architect Le Corbusier used RCC for various constructions. He believed that any shape and form was possible; if RCC is to be used.

For example, Notre Dame Du Haut, Ronchamp, France

This is an example of Le Corbusier Project where he used RCC like plastic.

What is RCC?

RCC means Reinforced Cement Concrete, i.e., cement concrete reinforced with steel bars, steel plates, steel mesh etc to increase the tension withstanding capacity of the structure.

Cement Concrete can take up immense compression but weak in tension whereas steel is good in withstanding both tension and compression.

Guide to Design of RCC Columns

Reinforced Concrete Columns

A column is a very important component in a structure. It is like the legs on which a structure stands. It is designed to resist axial and lateral forces and transfer them safely to the footings in the ground.

You can manually calculate the superimposed loads on a column in a structure using a simple process outlined in this linked article.

Columns support floors in a structure. Slabs and beams transfer the stresses to the columns. So, it is important to design strong columns.

A column is defined as a compression member, the effective length of which exceeds three times the least lateral dimension. Compression members whose lengths do not exceed three times the least lateral dimension, may be made of plain concrete.

The axial load carrying capacity of a column is deduced from the formula

axialload
Please see the link for formulas to calculate axial loads in columns. I would recommend using advanced structural design software like ETabs or Staad Pro for design of structures. Column design does not depend only on axial loads, but also on many other factors. There are bending moments and tortional forces induced due to beam spans, wind loads, seismic loads, point loads and many other factors.

In this article, we are going to discuss in detail the basis of classification of columns and different types of reinforcement required for a certain type of column.
