Input

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

Select the desire Load Group Name. Click the ... button to the right to enter additional load group names and modify or delete existing load group names.

Options

Add : To enter or add new continuous beam loads on beam elements connected continuously in a straight line

Replace : To replace previously entered continuous beam loads on beam elements connected continuously in a straight line

Delete : To delete previously entered continuous beam loads on beam elements connected continuously in a straight line

Concentrated Forces : Concentrated forces at a point in span

Concentrated Moments/Torsions : Concentrated moments/torsions at a point in span

Uniform Moments/Torsions : Uniformly distributed bending moments/torsions

Trapezoidal Moments/Torsions : Trapezoidal bending moments/torsions varying linearly along the beam length

Curved Load : Curvilinear load distribution based on a curve equation varying along the beam length

Curved Loads are loaded on three equally divided segments of elements. If an element is long, the load distribution becomes close to a straight line. So the elements need to be sufficiently divided to closely represent curved load distribution.

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.

Elements Selection

Line Beam Loads are applied to the elements on a straight line defined by two nodes.

Select Element

Line Beam Loads are applied to the selected elements.

Eccentricity

By assigning the eccentricity distance, the user can easily assign the eccentric load.

As shown in the picture below, by inputting the eccentricity distance and load, the program automatically converts them into 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-End : Eccentricity from the ith node

J-End : Eccentricity from the jth node

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.

Direction

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 continuous beam load is to be applied along the continuous beams or if the loading is to be vertically projected on the beams. 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 continuous beam load is applied to the continuous beams.

No : When a continuous beam load is applied along the continuous beams.

Value

Define if the loading positions of the continuous beam loads are to be entered in the relative ratio of a loaded beam length.

Relative : Relative ratio of a beam length

Absolute : Real beam length

x1, x2, x3, x4, W1, W2, W3, W4 : Refer to the guide diagram to specify the load magnitude and locations.

a, b, c : Constants defining the load distribution equation

When the Curved Load Type is selected, curvilinear distribution is given by

Enter the node numbers of the two ends of the continuous beams. The two node numbers may be set with the mouse using Node Snap in the working window.

Check in copy load to repeat the continuous beam loads for other rows of continuous beams.

Axis : Set the copy direction

x : UCS x-direction

y : UCS y-direction

z : UCS z-direction

Distances : Copy distances

When copying loads onto several rows of other continuous beams, enter the copy distances (spacings) as many times as required. (Ex, 5.0, 3.0, 4.5, 3@5.0)
