Distributed Loads
The following options are available for Distributed Loads:
1. Uniform Distributed Loads
The Uniform distributed loads dialog box
Use the + button (Add) to add a load/duplicate a selected load, and the X button (Del) to delete a created load.
Name: input a name for the uniform distributed load.
Load case: associate a load case from the dropdown list to the corresponding uniform distributed load.
Intensity: input the value of the uniform distributed load.
Definition point: define the reference point from where the abscissa is measured:
- Start of beam: the load abscissa will be measured from the start of the beam (from the first span).
- Start of span: the load abscissa will be measured from the start of the selected span.
- Start of span: define the span ID on which the definition point is considered.
Note: If the Definition Point is set to Start of beam, the Start of span is automatically set to Span #1 and greyed-out.
Abscissa: define the distance between the middle of support and the start point of the load.
Length: define the length of the uniform distributed load.
Fit to beam/span: expand the distributed load across the entire beam/span.
Note: The button changes depending on the selected Definition Point.
The Suspended Load button opens a dialog, where suspended loads can be defined.
From this dialog, the suspended load settings can be configured:
- Non suspended: if selected, the load will not be taken into consideration as a suspended load and thus the fields remain inactive.
- Links distribution (suspended with links spacing): additional links will be generated after calculation to take the effect of the load.
- Shear reinforcement (suspended using shear bars): shear bars will be generated after calculation to take the effect of the load.
Definition
Depth (h'): define the depth of the support reaction.
Shear reinforcement bending (only for the Shear reinforcement type of suspended load): define the type of bending for the shear reinforcement.
2. Variable Loads
The Variable Loads dialog box
Use the + button (Add) to add a load/duplicate a selected load, and the X button (Del) to delete a created load.
Name: input a name for the variable load
Load case: associate a load case from the dropdown list to the corresponding variable load
Left/Right Intensity: input the values of the variable load
Definition point: define the reference point from where the abscissa is measured:
- Start of beam: the load abscissa will be measured from the start of the beam (from first span)
- Start of span: the load abscissa will be measured from the start of the selected span
- Start of span: define the span ID on which the definition point is considered
Note: If the Definition Point is set to Start of beam, the Start of span is automatically set to Span #1 and greyed-out.
Abscissa: define the distance between the middle of support and the start point of the load.
Length: define the length of the variable load.
Fit to beam/span: expand the distributed load across the entire beam/span.
Note: The button changes depending on the selected Definition Point.
The Suspended Load button opens a dialog, where suspended loads can be defined.
3. Trapezoidal Loads
The Trapezoidal Loads dialog box
Use the + button (Add) to add a load/duplicate a selected load, and the X button (Del) to delete a created load.
Name: Input a name for the trapezoidal load.
Load case: associate a load case from the dropdown list to the corresponding trapezoidal load.
Intensity: input the value of the trapezoidal load.
Definition point: define the reference point from where the abscissa is measured:
- Start of beam: the load abscissa will be measured from the start of the beam (from first span).
- Start of span: the load abscissa will be measured from the start of the selected span.
- Start of span: define the span ID on which the definition point is considered.
Note: If the Definition Point is set to Start of beam, the Start of span is automatically set to Span #1 and greyed-out.
Abscissa: define the distance between the middle of support and the start point of the load.
Left side length/ Center side/ Right side length: define the length for each of the three zones of the trapezoidal load.
Fit to beam/span: expand the load across the entire beam/span.
Note: The button changes depending on the selected Definition Point.
The Suspended Load button opens a dialog, where suspended loads can be defined.
4. Uniform Linear Torsional Loads
The Uniform Linear Torsional Loads dialog box
Use the + button (Add) to add a load/duplicate a selected load, and the X button (Del) to delete a created load.
Name: input a name for the load.
Load case: associate a load case from the dropdown list to the corresponding linear uniform torsional load.
Intensity: input the value of the linear uniform torsional load.
Start span: define the span ID on which span the load placement will start.
End span: define the span ID on which span the load placement will end.
Abscissa: define the distance between the middle of support and the start point of the load; this field is grayed out and automatically calculated.
Length: the length of the linear torsional load; this field is grayed out and automatically calculated.
The Suspended Load button opens a dialog, where suspended loads can be defined.
Fit to beam: expand the uniform linear torsional load across the entire beam.
