TR.44 Printing Section Displacements for Members
This command is used to calculate and print displacements at sections (intermediate points) of frame members. This provides the user with deflection data between the joints.
General Format
PRINT SECTION (MAX) DISPLACEMENTS (NSECT i) (SAVE a) { NOPRINT | ALL | LIST memb-list }
Where:
- i = number of sections to be taken. Defaults to 12 if
NSECT
is not used and also if SAVE is used (max=24, min=2). - a = File name where displacement values can be stored and used by the STAADPL graphics program. If the
NOPRINT
command is used in conjunction with theSAVE
command, the program writes the data to file only and does not print them in the output. - This option is not necessary in STAAD.Pro.
Description
This command prints displacements at intermediate points between two joints of a member. These displacements are in global coordinate directions (see figure). If the MAX command is used, the program prints only the maximum local displacements among all load cases.
Example
PRINT SECTION DISPL SAVE
PRINT SECTION MAX DISP
SECTION DISPLACEMENTS
are measured in GLOBAL COORDINATES
. The values are measured from the original (undeflected) position to the deflected position. See figure above.
The maximum local displacement is also printed. First, the location is determined and then the value is measured from this location to the line joining start and end joints of the deflected member.
Notes
-
The section displacement values are available in Global Coordinates. The undeflected position is used as the datum for calculating the deflections.
-
This is a secondary analysis command. An analysis must be performed before this command may be used.
