Stability of slender column -How to improve the same ?

In the practical scenario, there are three main categories of stability, Stable Unstable Neutral Failure of structures may be also because of geometric instability. In the case of slender column, the slenderness or the stiffness of the column becomes more important. The capacity of material in the case of slender column is not fully utilized. …

Minimum and maximum reinforcement in column?

The column is a vertical structure that helps transfer the load from top to bottom in a framed structure. Specifically, columns transfer the compressive load from top floors, ceiling, or beam to the foundation or the beams. As we have already discussed in the previous port reinforced concrete beam is a composite section made of concrete and reinforcement. In …

Why do we use minimum eccentricity in column design?

When we design an axially loaded column, it is very important to consider some moments along with the axial load. As in the practical scenarios it is not possible to neglect the moment completely. According to IS 456:2000, in order to ensure the safety of column we should consider a minimum value of eccentricity. Also …

What is the difference between braced and unbraced column?

Column is basically a vertical structure, which helps to transfer the load from top to bottom in a framed structure. Specifically columns transfer the compressive load from top floors, ceiling or beam to the foundation or to the beams. Braced column are the structural component, provided so as to resist the lateral forces. Bracing prevents …

What is unsupported length and effective length of a column?

Column is basically a vertical structure, which helps to transfer the load from top to bottom in a framed structure. Specifically columns transfer the compressive load from top floors, ceiling or beam to the foundation or to the beams. The cross section of the column is mostly rectangular , square or circular. Sometimes we modify …

What is slenderness ratio & why is it important in design?

Slenderness ratio is a geometrical parameter, defined for a compression member (column). It is the ratio of effective length and lateral dimension of the compression member. It is also a measure of the structural vulnerability to the failure of the structure. . Generally we design the columns to resist the axial compression load. Sometimes a …

What is a column and what are the different types of column ?

Column is basically a vertical structure, which helps to transfer the load from top to bottom in a framed structure. Specifically columns transfer the compressive load from top floors, ceiling or beam to the foundation or to the beams. The cross section of the column is mostly rectangular , square or circular.

How do we check safety of a reinforced concrete beam?

Beam is one of the integral part of any structure. It is very important to check the safety of beam not only before construction but even after the construction stage. We ensure the safety of beam in the design phase by considering all the codal provisions. IS 456 : 2000 is the Indian standard code …

Why do we take factor of safety for concrete and steel ?

When we start with the design of a structure. It is very important to consider the structures safety and serviceability. As per IS 456: 2000, the structure should be capable to resist all the different forces that comes over the complete life. The estimation of force is done by considering different load combination which is …

What is neutral axis and what is the limiting depth ?

Let us consider an example where a beam is initially in unstressed position. Now when a uniform bending moment is applied along the length of beam , then the beam will bend. When the beam bends the top surface of the beam is in tension and the bottom surface is in compression. So it is …
