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.
