The "Add single beam" option allows for a single sloped beam from one point to another, either rectangular concrete or formed by a steel section.

This option is available in the "Sloped beams" menu that appears when you click on the option of the same name in the "Beams" menu, within the "Beam input" tab.

Data for the simple sloped beam

Clicking on the option opens the "Data of single sloped beam" window, where the following parameters are configured:

• Final group, Initial group
  These drop-down menus are used to select the groups of floors where the sloped beam starts and ends. The program does not allow you to select groups in which a floor grouping has been defined, as it would not be able to determine on which floor the beam ends or begins. If this is the case, these floors must be ungrouped. On the other hand, it is possible to pass through several intermediate floor groups.
• Single/Multiple
  This option is only active if there is a group of plants between the selected final group and initial group, and allows you to select the input mode:
  • The "Simple" option allows you to insert a single sloped beam between the selected end group and initial group of floors.
  • The "Multiple" option allows you to enter several sloped beams in several groups at once, located in the same position on the floor plan.
• Section type
  Sloped beams can be made of "Rectangular concrete" or consist of a "Steel section". To do this, select the desired option from the selector.
  • Rectangular concrete
    To define the section of the sloped rectangular concrete beams, enter the "Width" and "Depth" in the units indicated.
  • Steel section
    The options for defining the section of sloped steel section beams are as follows:
    • Material and section selection
      The button on the left opens the "Section selection" window, where you can select the material and section of the steel section from those available, including rolled steel sections, reinforced rolled steel sheet sections, and shaped steel sections.
    • Transposed
      The "Transposed" box allows you to rotate the section 90º counterclockwise.
• Connection at the ends
  It can be defined as "Bi-potentiometer" or "Bi-articulated".
• Buckling coefficients in the vertical and transverse planes
  This section allows you to define the buckling coefficients in the "Vertical" and "Transverse" planes of sloped steel section beams. You can select "With project coefficients" (as indicated in "Project > Beam options > Buckling coefficients for sloped steel beams and bracing") or "With own coefficients", in which case the user must enter them.
• Lateral buckling coefficients
  This section allows you to enter the lateral buckling coefficients in the "Upper flange" and "Lower flange" of the sloped steel section beams.

Loads on the sloped beam

Next, the program displays a table where you can "Add" or "Delete" loads on the sloped beam. The following parameters must be specified for each load:

• Load type
  Allows you to specify a load type. This can be "Uniform", "Point load", "Strip load", "Right triangular load" or "Left triangular load". Selecting each of these loads requires the subsequent entry of the parameters that define them. The help button at the top of the table displays a series of diagrams for each type of load that describe these parameters.
• Loadcase
  Allows you to assign the simple hypothesis to which the load will be associated.
• Value
  Allows you to indicate the value of the load. You can view the units in which the load value should be defined by hovering the pointer over the column heading.
• Ang.
  Allows you to define the angle formed by the load with the vertical axis of the structure. As a reference, a load with an angle of 0º indicates that it has the direction and sense of gravity; a load with an angle of 90º indicates that it is horizontal and has the same sense as the order of introduction of the beam you are going to introduce on screen.
• L1, L2
  These parameters allow you to define the points of application at the origin and end of strip or triangular loads, as well as the point of application of point loads. This distance is measured in true magnitude, i.e. along the beam and not as a horizontal projection from its origin.

Inserting the sloped beam in plan view

To insert a sloped beam, use the left mouse button to mark the starting point of the beam in the initial group. The program will then automatically move to the final group, where you can indicate the end point of the beam. The sloped beam can have a pillar or a horizontal beam as its starting and/or end point.
