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.

 

Eccentric loads can be applied to beam elements with reference to the GCS or ECS.

 

 

 

From the Main Menu select Load > Element Beam Loads.

 

Select Static Loads > Element Beam Loads in the Menu tab of the Tree Menu.

 

 

 

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 "Defualt", 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

 

 

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.

 

Direction: Input the direction of eccentricity

 

Distance: Input the distance of eccentricity

 

I-End: Eccentricity from the node

 

J-End: Eccentricity from the node

 

Eccentric Beam 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.
