The easy and fastest way to analyze the 2D-Truss problem right on your iPhone & iPod Touch. Featuring: • Standard Truss Templates: with the standard truss template (18 types of truss for initial version) , you can easily create and config your truss as required. • "Custom Truss"; If the built-in standard truss template doesn't match your requirement, "Custom" your own Truss is also easy to create due to the Node & Element generating features. • Unit Flexibility: very flexible in Units system, you can choose any units at your convenience without the requirement to restart the application and the unit system is saved per your truss's project. For example you use m. as node coordinations while you choose mm. for the deflection of the nodes or you can even choose in. or ft. for nodes's deflection (if you really need). • Buit-in material sections library where you can adjust any material's properties with no effect to other truss project. The options to create your own material library will be available for the next update. • PDF Reporting: All result information of your truss are shown in PDF and also you can email this result.
Rectangular Beam
This app assists in the design and analysis of reinforced concrete rectangular beams. It calculates required reinforcement, draws beam sections with rebar details, and provides strain distribution diagrams. Users can also determine crack width and deflection, and generate PDF reports.
- Reinforcement calculation
- Beam section drawing
- Layer requirement check
- Strain distribution diagram
- Crack width calculation
- Deflection calculation
- PDF report generation
