Stiffness analysis calculation

What the script does

calc-stiffness-1.py opens the sample project ../projects/beam-to-cont-column.ideaCon, selects the analyzed member, and runs a stiffness CBFEM analysis on the first connection.

Steps performed (real method names from the script):

1. Attach to a running Connection API service via ConnectionApiServiceAttacher("http://localhost:5000").create_api_client().
2. api_client.project.open_project_from_filepath(project_file_path) — open the .ideaCon project.
3. api_client.project.get_project_data(...) and api_client.connection.get_connections(...) — print project data and pick the first connection.
4. api_client.member.set_bearing_member(...) — set member id 2 as the analyzed member.
5. Build ConCalculationParameter() with connection_ids and analysis_type = "stiffness", then api_client.calculation.get_raw_json_results(...) — run the stiffness analysis and read the raw JSON results (the script parses the stiffnesess section).

How to run

1. Install the client package (the package version must match your installed IDEA StatiCa version):

   pip install ideastatica-connection-api
   

2. Start the Connection API service from your IDEA StatiCa installation folder (adjust to your installed version):

   "C:\Program Files\IDEA StatiCa\StatiCa 26.0\IdeaStatiCa.ConnectionRestApi.exe"
   

   The service listens on port 5000 by default, which is the baseUrl the script expects. Alternatively, start the service from Python with ConnectionApiServiceRunner (see the calculate_project_using_runner example).

3. Run the script from this folder (it locates the sample project via the relative path ../projects):

   python calc-stiffness-1.py
