Cable Stayed Bridge |
|
|
Auto-generate a two-dimensional shape of a cable stayed bridge using Cable Stayed Bridge Wizard. It generates symmetric and non-symmetric bridges with truss and box sloped girders. |

Enter the coordinates of the basic nodes defining a cable-stayed bridge. Type A: Origin point of the girder B: Top of the left tower C: Top of the right tower D: End point of the girder Height: Heights of towers H1: Height of the left tower H2: Height of the right tower Depth of Girder When the depth is not entered, the girder is modeled as a beam. And, when it is entered, the girder is modeled as a truss consisted of upper and lower chords connected by diagonal members. Material, Section Cable Girder Tower Select Cable Element Type: Assign the element type for the cable and hangers. Truss: Truss element Tension Only (Cable): Equivalent truss element for linear analysis & Elastic catenary element for nonlinear analysis are automatically selected. Distance from Girder to Tower: Horizontal distance separating the girder from the tower Shape of Girder: Slope and arc length signifying the curvature Left Slope (%): Slope at the left end of the arc Arc Length (m): Arc length Note Right Slope (%): Slope at the right end of the arc
Enter the distances between the cables and the heights of the cables located at the towers. Left: Cable spacings and heights in the left span Center: Hanger spacings and heights in the center span Right: Hanger spacings and heights in the right span Node No.: Display node numbers Member No.: Display member numbers
Bitmap: Display the position and shape representing the data. Drawing: Display the overall shape of the bridge using the data entries.

Q2. Can someone explain the idea behind drilling DOF in detail?
