Framelysis 1.9.1

Show solution: more methods 📖

  • Choose the method. The Solution panel has a method picker, and each method is tagged exact or ≈ approx. On phones it is a dropdown.
  • Moment distribution (Hardy Cross). Fixed-end moments, stiffness and distribution factors (a pinned far end uses 3EI/L), a distribution table that shows the first cycles and the totals, then end shears, reactions and a check. Frames that sway (one sway, e.g. a single-storey portal) get the classic two-stage sway correction.
  • Slope-deflection. The slope-deflection equation for every member, one joint equation per free rotation and one shear (sway) equation per sway, solved together, then end moments.
  • Force method (flexibility). Picks the redundants, shows the primary structure, δij and Δi0 (by virtual work), the compatibility equations and the redundants. Up to 4 redundants.
  • Stiffness method, step by step. DOF numbering, each member's stiffness matrix, assembly, the load vector with fixed-end forces, solving for displacements, then member forces and reactions. Big matrices fold away.
  • Portal method (approximate). For rectangular multi-bay frames under lateral loads: column shears (exterior V/2(n−1), interior twice), moments, then beam forces, compared with the exact analysis.
  • Sensible defaults: determinate → equilibrium, truss → method of joints, indeterminate without sway → moment distribution, sway or larger frames → stiffness. The portal method is never the default. Settings › General › Course method lets you make the stiffness method the default instead.
  • Run first, automatically. Show solution with no results runs the analysis first, with the Run screen, then opens the panel.
  • Hand methods neglect axial shortening, like the textbooks. Every result is checked against Framelysis's analysis; a small difference is explained as axial shortening instead of being flagged.

Look 🎨

  • The background glows follow your accent colour (Settings › Appearance › Accent colour), including the start-up screen.

Fixes 🐞

  • Opening several .STR files at once in the Android app: picking more than one file opened nothing. Each file now opens in its own tab.
  • Print / Save as PDF on phones and tablets. In the Android app, Print report (and Print view) opens Android's print screen, where Save as PDF is one of the printers. In phone and tablet browsers the report and Print view (View tab) open in a new tab, ready to print or save as PDF.
  • Opening GRASP .STR files on phones and tablets: they showed up greyed out in the file picker on Android and iPad. They can now be picked, and a .STR file is recognised by its content too, so one that lost its extension or was renamed (for example when sent through Messenger or Drive) opens instead of failing with "Not valid JSON". Any other kind of file gets a clear message.
  • Settings on phones: the sections are now a tab strip above the settings, so nothing scrolls sideways any more.
  • The "Drawing colours" row in Settings showed an internal name instead of its label.
