3.1 Detail Settings<br />
The individual designs are carried out by using the internal forces determined in RSTAB. Before<br />
you start the calculation by clicking the [Calculation] button, it is recommended to<br />
check the design details. The corresponding dialog box can be accessed in each input und<br />
output table by using the [Details] button.<br />
The Details dialog box provides the following tabs:<br />
• Resistance<br />
• Stability<br />
• Serviceability<br />

Consideration of Connections<br />
Often, zones near member connections show weakenings of the cross-section. It is possible<br />
to take into account this effect by a Reduction of limit tension stresses.<br />
The numbers of the relevant nodes can be entered manually or selected graphically by using<br />
the [Pick] button.<br />
The Connection length defines the zone on the member where reduced stresses are considered.<br />
In the input field below, enter the allowable Stress ratio in percentage.<br />
The maximum allowable stresses are applied outside the connection zone. If you want to<br />
reduce the allowable stresses also there, it is possible to enter a limit in the input field Stress<br />
ratio outside connections.<br />
