Arch

Use Arch Wizard to auto-generate an arch structure composed of a series of Beam Elements.

From the Main Menu select Structure > Wizard > Base Structure > Arch.

 Input & Edit tab

Type
Select an arch shape (circle, parabola at an equal projected spacing, parabola at an equal spacing, ellipse at an equal projected spacing, catenary at an equal projected spacing and catenary at an equal spacing)

Number of Segments
Enter the number of segments in the arch.

Boundary Condition
Select the support conditions (Pin, Fix or None) at both nodal ends of the arch.

L: Enter the horizontal projected length of the arch.

H: Enter the height of the arch.
 

• When the Arch Type is a Circle

R: Radius of the circle

theta: Angle of rotation
 

• When the Arch Type is a Catenary

Span(L)

Height(H)

Coeff.(m): m value of Catenary equation

Note
Catenary equation

Show Element No.
Display the element numbers of the generated arch.

Material
Enter the material property to be used.

Click to add a new material property or modify an existing material property.

Section
Enter the section to be used.

Click to add a new section or modify an existing section.

 Insert tab

Insert Point
Enter the coordinates of the insert point where the origin point of the created arch will be located in the existing model with respect to the GCS (UCS).
Alternatively, click the entry field and click the position of the insert point in the working window to enter the desired coordinates rather than typing in the entry field.

Rotations
Enter the rotational angles, Alpha, Beta and Gamma, that will define the orientation of the arch in GCS X, Y and Z respectively.

Merge Duplicate Nodes
Select the option whether to merge overlapping nodes between the existing model and the nodes pertaining to the newly created arch.

 : Set a tolerance for merging nodes.

Intersect Frame Elements
Select the option whether to divide the existing elements at the nodes pertaining to the newly created arch, which are in contact with the existing elements in the existing model.

 : Set an intersecting tolerance to allow for the division of elements.

Origin Point
Set the origin point of the newly created arch. This point is displayed in red in the Wizard Window.

Show No.: Display the node numbers making up the created arch.
