SOLIDWORKS TSA Bridge Analysis Tutorials

Welcome to cudacountry's SOLIDWORKS 2013 Bridge Structural Analysis Tutorials. We use SOLIDWORKS Weldments to design our bridge and SOLIDWORKS Simulation to analyze the structure.

Also, use Excel to create a spreadsheet with formulas to calculate, Safe Force, Total Load and Bridge Efficiency.

The tutorials use a bridge structure designed to meet Middle School Technology Student Association conference competitive events requirements.

The following tutorials with the PDF icon and MP4 icon are available for viewing. Download the free reader from Adobe.
