Floor Load tab

Used to apply a panel load which will be distributed on surrounding beams based on a two way distribution.

This load is a two-way distributed pressure load on members that circumscribe a panel. 

SettingDescription
Load Floor load value (force per unit area) in the current units. This load will act parallel to the global vertical axis.
XRANGE / ZRANGE / YRANGE options Select one of these options to specify a floor load by range of global coordinates
Group option Select this option to apply a floor load on a previously added member group or composite deck definition.
Pressure Specify the pressure of the floor load in the current force per square length units.
Direction

The floor load may be considered as acting perpendicular to the plane of the panel on which it is defined. This is the normal static load condition. However, for the purposes of generating the mass matrix for dynamic analysis, it may also be considered as weights lumped at the nodes of its panels and acting (vibrating) parallel to the plane of the panel. Hence, the user has the choice of specifying it in one of the 3 global directions.

Note: Refer TR.32.4.3 Floor Load Specification for more information.
Define X Range / Y Range / Define Z Range

Specify the location of the floor using the Define X Range option. The load will be calculated for all members lying between this range.

Corner points of the area on which the floor load acts, in global X and Z directions. If omitted, the floor load is assumed to be acting for all members located within the Y range specified.

One Way Distribution

Select this option to use one way distribution to get a one way type distribution of the pressure. In such cases the program finds out the shorter side of the panel. It then divides the load in between the long direction beams . No load is generated by this option if the panel is square in shape.

To specify a floor load with the Z-axis vertical, select the Floor With Z Range menu option.  The data items are the same as the Floor load with Y axis vertical except that the Y and Z axes are interchanged.

Towards (One Way Distribution) Used to define the direction in which the load is spanning by selecting a member in the loaded zone onto which the load is to be directed. The default is for the load to resolve toward the longer span of supporting beams framing the Floor load. However, you can select a beam number to direct the load to that beam.
Panel Information Output group
SettingDescription
Print to output file

Includes the floor panel information in the output file (.ANL).

Print Options (output file):
  • Print - The total number of panels identified, total area of all panels and total load generated will be printed in the output file.
  • Panel with member list - This option is used to print panel member numbers on which loads are generated in addition to the Print option output.
  • Panel with member load - This option is used to print panel loading information in addition to the Print with member list option output..
Print to external text file

This option will output the panel information in an external text file named (filename) _FLD.TXT.

Print Options (external text file):
  • Panel with member list - This option is used to print panel member numbers on which loads are generated. Additionally, the total number of panels identified, total area of all panels and total load generated will be printed in the text file.
  • Panel with member load - This option is used to print panel loading information in addition to the Print with member list option output..
