Structural Analysis – Step 4
Step 4
Draw Load tributary areas on the frame-line diagram. Compute Area and the corresponding loading at the beam.
Tributary Area at the selected/highlighted beam
You can create your own Load computation module/spreadsheet.
Structural Design Step by Step
STEP 1
Analyse structure’s trusses using Wind Load Analysis.
STEP 2
Compute Truss Member forces and Reaction at Supports
STEP 3
Trace the Structural Framing to 3D Line Diagram.

Structumatrix Beam 2010 now available
This has been long delayed but anyhow, Structumatrix Beam module 2010 version will now be released to the public for free.
Structumatrix Beam 2010 is an executable file (.exe) and is good for rectangular doubly reinforced concrete beam conforming to NSCP/ACI code.
I have tested this with Vista and XP, there has been no problem but if you encounter one, please report it so we can issue fixes.
History
1. Structumatrix was first created using spreadsheet application. (6 years ago)
2. After studying Visual Basic, I started converting my spreadsheets into stand-alone applications. (1 year ago)
3. Structumatrix beta was released (8 months ago)
4. Release of Structumatrix Beam 2010 (Today, Sept 7)
