Latest version: 1.4 — Updates to section library

Description

Structural/Civil Engineering App for single-span beams.

Caters for many beams with arbitrary loadings. There is an emphasis on quick and precise input of high-resolution data through graphical drag-and-tap interaction, with numeric input available as an alternative. Instantly available, clear graphical representations of deflections and force envelopes are interactive with slider bars for reading off results at any point along the beam, together with single-tap access to maxima/minima and other points of interest.

  • Beam lengths from 0.2 m to 40 m (6” ~ 1600”).
  • Loads from 0 kN to 1000 kN (0 kips ~ 200 kips).
  • Arbitrary combined loadings of point, couple, and trapezoidal loads.
  • Various end conditions:
    • Simply supported.
    • Fixed both ends.
    • Fixed and pinned at opposite ends.
    • Left-hand and right-hand cantilevers.
  • Instant automatic analysis on every change to dimensions, end restraints, properties, and loadings.
  • Results include:
    • Reactions.
    • Deflections.
    • Bending moments.
    • Shear forces.
    • Stress.
  • Results at any position along the beam.
  • Points of interest automatically determined:
    • Local and global maxima & minima.
    • Zero intercept.
    • Zero crossing points.
User Interface
  • Four simple interactive screens:
    • Geometry: for entering beam length, supports, and section properties.
    • Loading: for adding, removing, and editing loads.
    • Results: for reading numerical results and viewing graphical deflections and force envelopes.
    • Utilities: for selecting unit system (metric/imperial) and resetting the model.
  • Easy and accurate graphical drag-and-tap controls:
    • Precision of positioning with finger as high as 1 part in 2000.
    • Drag slider for beam span.
    • Tap to add a load to the beam.
    • Drag loads along to set position.
    • Drag loads and envelopes to specify magnitudes.
    • Drag a load to the wastebin to remove it.
    • Drag marker along deflected shape or force envelope to read off value.
    • Tap on points of interest for specific results (e.g. maxima/minima).
  • Numeric entry available if preferred:
    • Double-tap on an input variable to enter its value numerically instead of graphically.
  • Section library presented as a straightforward selection:
    • Tap on button in geometry window to open library.
    • Tap on category (e.g. British UB).
    • Tap on section size.
    • Diagram and properties will appear; tap on a Use button to pick major or minor axis.
  • Custom property generator accessible in the library:
    • In library, choose custom category.
    • Diagram and properties will appear; double-tap on a dimension to edit it.
    • Properties will automatically recalculate when dimensions are changed.
    • Choose a material (optional) by tapping on the blue button.
    • Tap on the Use buttons to pick either major or minor axis.
