AlphaCalc is dedicated to building cloud based web applications for structure engineers. It serves as a platform to bring engineers together and share their knowledge with others. All the applications can be run in your web browser without installation. Register an account with less than 30 seconds and try it out.
We want to hear from you! Please send us your questions, comments and ideas.

Applications we currently have are listed below. More powerful tools are coming soon.

Prestressed Concrete Pile PM Interaction Diagram
This web application generates PM interaction diagram for prestressed precast concrete piles w/wo slenderness effects. It performs design check for axial force and bending moment from user's input. The interaction diagram data can be exported to Excel and a PDF analysis report can also be generated. This application is licensed with Washington State Department of Transportation(WSDOT)’s Alternate Route Open Source License. Please visit WSDOT Bridge Engineering Software site for more information.

Reinforced Concrete Section PM Interaction Diagram
This web application generates PM interaction diagram for reinforced concrete sections. It performs design check for axial force and bending moment from user's input. The interaction diagram data can be exported to Excel and a PDF analysis report can also be generated.

Seismic Design Map
This map application incorporates US seismic design data from USGS and serves as a powerful tool for seismic design and earthquake data lookup. It supports address input, latitude/longitude input and direct pin placement on any location on the map. This application calculates design response spectrum for different design criteria. It currently supports IBC 2006, IBC 2009,ASCE 7 2005, ASCE 7 2010 and 2009 AASHTO Guide specifications for LRFD seismic bridge design.

Moment Curvature Analysis
This web application performs moment curvature analysis for reinforced concrete sections. It supports mild steel, prestressing steel, unconfined concrete and confined concrete modeling. The interactive analysis result display facilitates hinge property definition for pushover analysis. The moment curvature analysis data can be exported to Excel and a PDF analysis report can also be generated.
