OS. Microsoft Excel Macro Example

A Microsoft Office Excel spreadsheet which can be used to check the capacity of a rectangular, reinforced concrete beam.

This spreadsheet file checks the bending capacity of a rectangular concrete beam with the reinforcement already laid out. The capacity is checked against the maximum sagging moment produced from a series of load cases. The beam is analyzed in STAAD.Pro. The results are extracted and linked into Excel using OpenSTAAD and VBA.

In STAAD.Pro, select the Sample Models link on the Open tab of the Start page.
Select US/US-8 Concrete Design for a Space Frame.STD and the click Open.
Selet the Run Analysis tool in the Analysis group on the Analysis and Design ribbon tab.
The macro relies on having analysis results.
Open the C:\Users\Public\Public Documents\STAAD.Pro 2024\Samples Sample Models\OpenSTAAD\Rectangle-Beam.xls file in Microsoft Office Excel.

Note: Excel will warn of macros present in the file. Simply click the Options… button in the Security Warning message area to open the Microsoft Office Security Options dialog, where you will select the Enable this Content option and click OK.
Select the STAAD.Pro Output worksheet.

The calculations for checking the capacity are located on the sheet marked Concrete while the extraction of the values from STAAD occurs on the sheet marked STAAD.Pro Output.
Type a member number in cell B7.
Member 14 is entered by default.
Click Results.
The STAAD.Pro results are read into the spreadsheet along with the beam size. Then the Concrete worksheet is selected for you.

The rest of the Concrete worksheet performs concrete beam design for the selected member based on the moment and dimensions.
