Deflection Pro

• 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.

Designing members for combined forces and torsion has never been easier! This major release ties together analysis and design of different load types through interaction equations and comprehensive cross section stress analysis. From billet to beam, this update was reheated, rerolled, and refined to exacting tolerances. • NEW: Interaction equations for symmetric members under combined flexure and axial and HSS members under combined torsion and other loads. The equations are conservative and based on AISC Chapter H. If combined flexure is present, a chart showing the interaction value along the entire beam will be displayed under the Flexure charts. If combined torsion is present (for HSS), a corresponding chart will be displayed under the Torsion charts. • NEW: Combined stress analysis and design. A new results section for Combined Stresses is available to handle complex torsional analysis and design of non-HSS shapes per AISC Chapter H. When torsion is present, safety factors are applied as required in the specification. When torsion is absent, these charts become supplementary, so their safety factors are disabled to prevent this conservative analysis from governing over strengths calculated for separate load types. The header will change to "Nominal Stress Analysis" when safety factors are not included. • NEW: Force loads (both point and distributed) can now specify an eccentricity value to capture common torsional use cases. The eccentricity amount can be specified in the last input box after the angle components within the load list view. • NEW: Distributed torsional loads. With the new load eccentricity feature, distributed torsional loads can now be specified and analyzed, making it possible to now handle new use cases. • NEW/CHANGE: In the beam editor, fixed supports now impose a fixed torsional warping constraint. In other words, they are "torsionally fixed". This leads to higher warping stresses but a smaller torsional rotation. In other words, "fixed" supports now mean "flexurally and torsionally fixed", whereas "pinned" supports continue to mean "flexurally and torsionally pinned". • NEW: Design example files for combined forces and torsion. Torsional examples now leverage the new eccentricity value instead of needing to specify a separate force and moment. • NEW: The beam editor layout for large screens was simplified and redesigned to make better use of screen space and bring results closer into view. If the screen is wide enough, two separate scrollable panels are now displayed side-by-side. The first panel focuses on inputs and the second panel focuses on results (with some inputs sprinkled in). • FIXED: The horizontal deflection curve was wrong in some cases, and it is now fixed. • IMPROVED: As usual, many other minor improvements and fixes throughout the app were made.
