< Floor Load Dialog >

Name : Enter the name of floor load to be created.

Load Type : Select the type of floor load. "Floor Load Type" dialog can be accessed through button.

Set : Select a static load set in which the specified load is included.

Load Distribution

Type : Define the distribution type of floor load.

One Way : One way distribution

Two Way : Two way distribution

Polygon-Centroid : Load distribution based on the areas of triangular segments created by dividing a polygon relative to the centroid

Polygon-Length : Load Distribution proportional to the lengths of the members forming the area.

Angle : Angle defining the direction of the load to be distributed.

Load angle is applicable only for "One Way" Distribution. It is an angle formed by the line connecting the 1st point to the 2nd point defining the loaded area and the load distribution direction.

Define Sub Beam

Consider Sub Beam : Check to consider sub beam member for floor load distribution.

Method : Select how to consider sub beam member in calculation of floor load.

Direct Loading : Distribute the load directly to sub beam member.

Load Transfer : Transfer the load to main member which is acting on unmodeled sub beam member.

Unmodeled Sub Beam : Define unmodeled sub beam member..

Number : Number of sub-beam members.

Angle : Placement angle of the sub-beam members.

Unit Self Weight : Self-weight per unit length of a sub-beam member (load/length).

Floor Load Area

Define the area of floor load.

Add : Add new area.

Delete : Delete assigned area.

Direction

Direction : Define the direction of floor load.

Local x : Floor load applied in the x-direction of the floor plate local coordinate system

Local y : Floor load applied in the y-direction of the floor plate local coordinate system

Local z : Floor load applied in the z-direction of the floor plate local coordinate system

Global X : Floor load applied in GCS X-direction

Global Y : Floor load applied in GCS Y-direction

Global Z : Floor load applied in GCS Z-direction

Projection : When the Floor Load direction corresponds to 'Global X, Y or Z', select the option whether or not to project the floor load vertically.

Yes : Floor load is applied to the area projected on a plane perpendicular to the loading direction.

No : Floor load is applied along the plane of the structure.
