Function
- Enter beam loads acting on beam elements such as uniformly distributed loads or in-span concentrated loads. Modify or delete previously entered beam loads.
Call
From the main menu, select [Load] tab > [Type : Static Loads] > [Static Loads] group > [Beam Loads] > [Element]
Input
Element Beam Loads dialog box
Load Case Name
Assign the load case name. Click the ... button to the right to enter, additional load cases and modify or delete existing load cases.
Load Group Name
Select the desired Load Group that will include the entered Element Beam Loads data. Select "Default", if a Group assignment is unnecessary. Click the ... button to the right to add, modify, or delete Load Groups.
Options
Add : To enter new or additional beam loads acting on beam elements
Replace : To replace previously entered beam loads acting on beam elements
Delete : To delete previously entered beam loads acting on beam elements
Load Type
Assign the loading type of beam loads. The loading types are as follows :
Concentrated Forces : Concentrated forces at a point in span
Concentrated Moments/Torsions : Concentrated moments/torsions at a point in span
Uniform Loads : Uniformly distributed load
Uniform Moments/Torsions : Uniformly distributed bending moments/torsions
Trapezoidal Loads : Trapezoidal load varying linearly along the beam length
Trapezoidal Moments/Torsions : Trapezoidal bending moments/torsions varying linearly along the beam length
Uniform Pressure : Uniform pressure load that is entered per unit area considering the section shape.
Trapezoidal Pressure : Trapezoidal pressure load that is entered per unit area considering the section shape.
Eccentricity
By assigning the eccentricity distance, the user can easily assign an eccentric load.
As shown in the picture below, by inputting the eccentricity distance and load, the program automatically converts them to an equivalent moment. This function is convenient to assign an eccentric beam load, such as wind load.
from Offset : Eccentricity from the node with the Section Offset considered
from Centroid : Eccentricity from the centroid
Input of the load using the eccentricity
Eccentricity
Direction : Input the direction of eccentricity.
Distance : Input the distance of eccentricity.
i-th End : Eccentricity from the i-th node
j-th End : Eccentricity from the j-th node
Additional H from Top
This option becomes active when the Load Type is Uniform Pressure or Trapezoidal Pressure.
As shown in the figure below, apply the pressure load considering the height of the barrier H that is not the part of the model. Additional H is the distance from the top in the Local y or z (+) direction depending on the load direction.
Additional H for entering the pressure load
Direction
Set the direction of beam loads. The loading directions are as follows:
Local x : Beam load applied in the element local x-direction
Local y : Beam load applied in the element local y-direction
Local z : Beam load applied in the element local z-direction
Global X : Beam load applied in GCS X-direction
Global Y : Beam load applied in GCS Y-direction
Global Z : Beam load applied in GCS Z-direction
When the loading direction does not correspond to the above 6 directions, enter the force components in each direction with appropriate signs.
Projection
Define if the beam load is to be applied along the entire beam length or if the loading is to be vertically projected on the beam. This command takes effect only when the load type is 'Uniform Loads' or 'Trapezoidal Loads' and the loading direction is 'Global'.
Yes : When a vertically projected beam load is applied to the beam
No : When a beam load is applied along the entire beam length
Value
Define if the loading positions of the beam loads are to be entered in the relative ratio of the beam length.
Relative : Relative ratio of the entire beam length
Absolute : Real beam length
Refer to the figure at the bottom of the Load Type selection field to enter the loading positions for the corresponding loading type and its magnitude. The location of the load is inputted as a distance or distance ratio from the N1 node.
