STAAD.Pro Help

Transfer Forces for Selected Members dialog

Used to report transfer forces across beam connections on either side of columns for a selected set of members.

STAAD.Pro calculates the "Transfer force" (i.e., "pass through force"), which can be used for connection design. This feature is based on a paper on the subject by Dr. William. A. Thornton.

Transfer force is simply the maximum net horizontal force that gets transferred from the one side of the column to the other through the connection. So STAAD.Pro checks the forces in the members framing into each side of the column and finds out the resultant horizontal force for either side. Typically the resultant forces on the two sides would not be equal as some amount of force will be taken up by the column in shear. The greater of the two resultants is reported by STAAD.Pro as the transfer force. The option to determine transfer force automatically, will save engineers considerable time and effort as in most cases, they have to report the transfer forces in the design drawings. The same concept can be applied to floor bracing in horizontal plane.

Opens when the Report >  Column Transfer Forces tool is selected in the Reports group on the Results ribbon tab.

Loads Displays the load cases that has been considered to calculate the transfer force. By default, all load cases are considered but one can exclude a few of them by simply clicking on the load case within the Loads box.
Left / Right Beams List all the members on the respective sides of the column along with their incidences. The boxes Left TF and Right TF shows the resultant horizontal force from either side. Max TF reports the transfer force.
Insert to Table

Generates the Transfer Force Report table which contains all the transfer force information and can be included in reports.
