The GSAGH sample files are designed to help engineers and designers explore structural modelling workflows using GSA (General Structural Analysis) integrated with Grasshopper, a visual programming environment within Rhino.


These sample files demonstrate a wide range of structural modelling techniques and analysis capabilities. Below is a categorized summary of what’s included:

Sample Files
1. 3D Boxes.gh – Volumetric modelling and meshing.
2. 4 Point surface with mid-support.gh – Surface modelling with internal support conditions. Galapagos is used to find the optimum internal support position.
3. Connection modelling.gh – Modelling of a connection.
4. Edit & update existing models.gh – Enables dynamic editing of GSA models.
5. Flat slab meshing.gh and .3dm – Demonstrates meshing for slab structures.
6. Footfall.gh – Simulates dynamic response to pedestrian movement.
7. Gerber member.gh – Beam modelling.
8. Grid loads.gh - Model defined with Grid area load, grid line load and grid point load.
9. Inclined column tower.gh – Models complex column geometries.
10. Member loading.gh – Applies loads to structural members for analysis.
11. Moment frame structure.gh – Models a rigid frame system and demonstrates how to set up a moment-resisting frame using parametric inputs.
12. Reciprocal frame.gh – Showcases parametric modelling of architectural and structural forms.
13. Soil tunnel.gh – Integrates geotechnical elements like tunnels.
14. Spatial truss.gh – Builds and analyses a space frame.
15. Spring and link.gh – Modelling spring and link elements.
16. Staircase.gh – Models a staircase and performs footfall analysis.
17. Truss.gh – Builds and analyses truss.
18.	Various modes.gh - Runs model stability, modal buckling and modal dynamic analyses.
