Types.

Examples.

Basic Principals.

Curves.

Effect.

Differences.

A tension or compression stress created in a structural member by the application of a length wise axial load.

Loads pass through the centroid

of the section.

• Member is straight.

• Load less than buckling load.

Tensile stress:

It is an Axial Stress The force is

along the axis of the member)

It is a force that "EXTENDS“

the member. (Pulling it apart)

Compressive stress:

It is also an Axial Stress

It is a force that "CONTRACTS“

the member. (Crushing it inwards)

EXAMPLES OF

TENSILE AXIAL STRESS

Chain Carrying a Load Tension Cable On a Bridge

Decorative Column in architecture

Steel Structure Of High Rise Building

The difference between the cracking patterns of the two beams (B-1 & B2) can be attributed to the effect of the compressive axial stresses that reduced the load tensile stresses and prevented the extension of the cracks.

AXIAL, FLEXURAL, NORMAL &
