# Stress

## Information on all the member stresses evaluated by SkyCiv Structural Software

Display the single-member stress values acting on each member of your structure. The stress types that can be viewed are separated based on their component local axis directions and include:

• Top Bending Z
• Top Bending Y
• Btm Bending Z
• Btm Bending Y
• Shear Y
• Shear Z
• Axial (X)
• Top Combined Z
• Top Combined Y
• Btm Combined Z
• Btm Combined Y

## Local Axes

The diagram below explains how local axes are described for each member to better visualize how stress results are represented.

• Local X-axis – In the direction along the length of the member (longitude axis).
• Local Y-axis – In the direction of the altitude axis. The vertical axis of the cross-section.
• Local Z-axis – In the direction of the lateral axis. The horizontal axis of the cross-section.

## Top Bending Z

The top fiber bending stress about the local Z axis. Acts in the local X-axis.

## Top Bending Y

The top fiber bending stress about the local Y-axis. Acts in the local X-axis.

## Bottom Bending Z

The bottom fiber bending stress about the local Z axis. Acts in the local X-axis.

## Bottom Bending Y

The bottom fiber bending stress about the local Y-axis. Acts in the local X-axis.

## Shear Y

The shear stress in the local Y-axis.

## Shear Z

The shear stress in the local Z axis.

## Shear Z

The shear stress in the local Z axis.

## Axial (X)

The axial stress in the local X-axis.

## Top Combined Z

The sum of all stresses acting about the Z local axis direction at the top fiber. Sum of Top Bending Z and Axial (X).

## Top Combined Y

The sum of all stresses acting about the Y local axis direction at the top fiber. Sum of Top Bending Y and Axial (X).

## Bottom Combined Z

The sum of all stresses acting about the Z local axis direction at the bottom fiber. Sum of Btm Bending Z and Axial (X).

## Bottom Combined Y

The sum of all stresses acting about the Y local axis direction at the bottom fiber. Sum of Btm Bending Y and Axial (X).
