Automate the design of bridges and trusses using generative design 01

 

1-1. Key Information for Bridge Design Automation

 The basic setup is configured as shown in the image above, with the CONTROL PANEL set as the input values. The corresponding input values are as follows:

1. Z Component (Height adjustment along the Z-axis)
2. Divisions (Number of divisions)
3. Top Chord Size (Size adjustment)
4. Bottom Chord Size (Size adjustment)
5. Vertical Chord Size (Size adjustment)
6. Diagonal Chord Size (Size adjustment)

To implement Generative Design, the above input values and additional design elements are configured. Additional output information to be added during later revisions includes the Sum value for verifying the Surface Area, used to correct Voronoi geometry errors. This will be explained in detail during the latter revisions. Furthermore, as additional design elements beyond the stable truss structure are incorporated, a coefficient slider will be added to modify the point array.

1-2. Bridge Design Automation Process

Step 1: Basic Truss Structure

• Verify truss structure arrangement method and mark connection points.

Step 2: Modified Truss Structure

• Ensure stability of the truss structure arrangement and determine feasible ranges for GD modifications.

Step 3: Adding Design Elements with Top NurbsCurve

• Incorporate a top NurbsCurve to extract and verify asymmetrical shapes for additional design elements.

Step 4: Adding Design Elements with Top and Bottom NurbsCurves

• Incorporate a bottom NurbsCurve to reflect overall design elements.

Step 5: Adding Design Elements with Top NurbsCurve and Voronoi

• Maintain the top NurbsCurve while adding Voronoi for structural stability and additional design features.
