From b989ee868fbee9087ddb64655fb9a0fdaf844cb7 Mon Sep 17 00:00:00 2001 From: "Phornjed Ph." Date: Sat, 2 Aug 2025 20:00:37 +0700 Subject: [PATCH 1/4] Add tests for shear force and bending moment diagrams, and validate Foundation Design imports - Implemented a new test script for shear force and bending moment diagrams in `test_shear_moment_diagrams.py`. - Calculated shear and moment distributions based on foundation and column parameters. - Created visualizations for shear force and bending moment diagrams using Plotly. - Added a new test script `test_streamlit_imports.py` to validate imports from the FoundationDesign package. - Included tests for load factors, strength reduction factors, material validation, and design information retrieval. --- .streamlit/config.toml | 74 + CHANGELOG.md | 181 + FoundationDesign/__init___aci318.py | 273 ++ FoundationDesign/concretedesignfunc_aci318.py | 579 +++ FoundationDesign/foundationdesign_aci318.py | 784 ++++ NEW_FEATURES.md | 106 + QUICK_START.md | 148 + README_ACI318.md | 195 + STREAMLIT_README.md | 208 + complete_design_example.py | 246 ++ .../Concentric_Footing_ACI318_Example.ipynb | 567 +++ improved_foundation_analysis.html | 3885 +++++++++++++++++ improved_foundation_analysis.py | 167 + requirements_streamlit.txt | 6 + run_streamlit.bat | 8 + setup_dev.py | 111 + setup_new.py | 48 + streamlit_app.py | 1081 +++++ test_aci318_basic.py | 181 + test_direct_usage.py | 173 + test_plotly_chart.html | 3885 +++++++++++++++++ test_plotly_chart.py | 48 + test_shear_moment_diagrams.html | 3885 +++++++++++++++++ test_shear_moment_diagrams.py | 126 + test_streamlit_imports.py | 51 + 25 files changed, 17016 insertions(+) create mode 100644 .streamlit/config.toml create mode 100644 CHANGELOG.md create mode 100644 FoundationDesign/__init___aci318.py create mode 100644 FoundationDesign/concretedesignfunc_aci318.py create mode 100644 FoundationDesign/foundationdesign_aci318.py create mode 100644 NEW_FEATURES.md create mode 100644 QUICK_START.md create mode 100644 README_ACI318.md create mode 100644 STREAMLIT_README.md create mode 100644 complete_design_example.py create mode 100644 examples/Concentric_Footing_ACI318_Example.ipynb create mode 100644 improved_foundation_analysis.html create mode 100644 improved_foundation_analysis.py create mode 100644 requirements_streamlit.txt create mode 100644 run_streamlit.bat create mode 100644 setup_dev.py create mode 100644 setup_new.py create mode 100644 streamlit_app.py create mode 100644 test_aci318_basic.py create mode 100644 test_direct_usage.py create mode 100644 test_plotly_chart.html create mode 100644 test_plotly_chart.py create mode 100644 test_shear_moment_diagrams.html create mode 100644 test_shear_moment_diagrams.py create mode 100644 test_streamlit_imports.py diff --git a/.streamlit/config.toml b/.streamlit/config.toml new file mode 100644 index 00000000..78eb3167 --- /dev/null +++ b/.streamlit/config.toml @@ -0,0 +1,74 @@ +[global] + +# If false, will attempt to open a browser window on start. +showWarningOnDirectExecution = false + +[logger] + +# Level of logging: 'error', 'warning', 'info', or 'debug'. +level = "info" + +[client] + +# If false, will attempt to open a browser window on start. +showErrorDetails = true + +[server] + +# List of folders that should not be watched for changes.
