About this app
Deflection Pro is an advanced structural analysis calculator for beam, truss, and frame design. The software is designed to be simple, intuitive, and useful for structural engineers worldwide. Like our other apps, it is designed to run on all your devices. LOAD COMBINATIONS Deflection Pro generates common load combinations based on American and European standards. Simply select a desired design method in the settings page and assign a category to each load. The results are seamlessly aggregated and integrated into the same charts and interface as if you were designing a simple beam case. BEAM COLUMN CAPACITY CHECKS Deflection Pro calculates beam column strength capacity for flexure, shear, tension, and compression based on the AISC specification. The software accurately reproduces tabulated values in steel construction manuals. Flexure Design • Yielding • Lateral torsional buckling • Local buckling • Flange local buckling • Compression flange local buckling • Web local buckling • Compression tee stem local buckling Shear Design • Web shear strength • Web shear strength, considering field action Tension Design • Yielding tensile strength • Rupture tensile strength Compression Design • Flexural buckling • Torsional buckling OTHER FEATURES Since this is our latest and greatest structural analysis app, we are actively improving it and adding new functionality. It receives more frequent updates than other tiers of our software. Other advanced functionality include the ability to directly export to PDF and to save to an external file for backup and sharing. CONTACT We like to hear from you! Please email contact@ketchep.com if you have any issues, questions, or comments.
Latest release
What’s New
• IMPROVED: Significant improvements in calculation speed and CPU/memory management when working with large models and large numbers of load combinations. • NEW: Open *.deflection files directly from the Files app (recommended). • NEW: Multitasking window support. Open separate windows to work on multiple files at a time. • FIXED: You can now open our files from certain 3rd party file sharing apps. • NEW: Canadian load combinations. • FIXED: Transient calculation glitch caused by deleting nodes in the 2d editor. • FIXED: Error in deflection curves under certain situations when Timoshenko was enabled. • FIXED: App crash due to very large models, particularly in smaller devices. • FIXED: Error in EU load combinations triggered when multiple live loads with a load factor of 1 were present.
