1. Software for economic concrete design Efficient Analysis with the Strand7 API Doug Jenkins - Interactive Design Services

2. Introduction What is an API? ST7 Tools Spreadsheet Example Applications Case Study

3. What is an API? Programming interface allowing read/write access to Strand7 data from external programs Interface files provide for Visual Basic and VBA, C++, Delphi, Fortran (and Matlab in next version) Requires some programming!

5. ST7 Tools Spreadsheet Allows complete Strand7 model file data to be written to and from Excel spreadsheets Read analysis results for selected elements Adjust element properties and run analysis from the spreadsheet Run staged analyses – e.g. Backfill of buried structures Calculate stresses and member capacity directly from Strand7 output Greater control of graphical output Access geometric data in Strand7 models

6. Example Applications Simple frame analysis Complex 3D beam and plate analysis – suspension bridge Analysis of laser scan data Case Study – Analysis of large twin buried arch structure under high fill –RC Design Functions Spreadsheet
