Concrete Column Design

For design purposes the columns are separated into two categories. These columns are referred to as short columns.

Pin Di Beam

In the last post we analysed a concrete column in a frame structure for vertical actions.

Concrete column design. A reinforced concrete column is a structural member designed to carry compressive loads composed of concrete with an embedded steel frame to provide reinforcement. The design of reinforced concrete columns and beams is very important to provide structural strength to a building and particularly to withstand earthquakes and other natural disasters. Columns are the major elements in reinforced concrete structures and the safety and stability of the structure greatly depends on it.

The subject of this post is the design of reinforced concrete columns to bs en 1992 1 1 eurocode 2. Economical design of reinforced concrete columns and its construction practices and recommendations to reduce its cost of construction is discussed. It is like the legs on which a structure stands.

The majority of reinforced concrete columns in practice are subjected to very little secondary stresses associated with column deformations. Axial loads and bending moments. Short columns and slender columns.

Secondary stresses associated with deformations are usually very small in most columns used in practice. Columns are used as major elements in trusses building frames and sub structure supports for bridges e g. The majority of reinforced concrete columns are subjected to primary stresses caused by flexure axial force and shear.

These columns are designed as short columns using the column interaction diagrams presented in chapter 3. Columns are structural compression members which transmit loads from the upper. However the column was not designed because the design of columns has not been presented before.

Diagonal and horizontal compression elements in a truss. Here we look at the design of columns and beams the placement of the concrete and steel and how these give structural strength. The concrete column module designs concrete rectangular or circular columns against axial uniaxial or biaxial bending as well as shear based on aci 318 02 05 08 11 14 code provisions.

It is designed to resist axial and lateral forces and transfer them safely to the footings in the ground. Columns are usually considered as vertical structural elements but they can be positioned in any orientation e g. Design of concrete structures part 1 1.

This article is a structural overview of concrete column design when subject to axial loads and bending moments. Reinforced concrete columns a column is a very important component in a structure. General rules for buildings.

The program generates exact not approximate or empirical p mx my interaction surfaces for all sections according to user specified design criteria.
