Element Beam Loads

 

 

 

Enter beam loads acting on beam elements such as uniformly distributed loads or in-span concentrated loads. Modify or delete previously entered beam loads.

 

 

 

From the Main Menu select Load > Static Load > Element Beam Loads.

 

 

Load Case Name

Assign the load case name. Click to the right to enter, additional load cases and modify or delete existing load cases.

Load Group Name

Select the desire Load Group that will include the entered Element Beam Loads data. Select "Default", if a Group assignment is unnecessary. Click 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.

End: Eccentricity from the  node

End: Eccentricity from the 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.
