Description

Structural/Civil Engineering App for single-span beams.

Caters for beams with various end supports and with arbitrary loadings composed of any mix of point loads, moments, and distributed loads. Beam properties may be entered numerically or by simply tapping and dragging, with an extensive multi-national section library built-in, plus a section generator for custom-sized cross-sections of common shapes.

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, with smooth curves and sharp discontinuities, 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.

Loads can consist of any combination of point loads, couples, UDLs, and trapezoidal distributed loads at any points along the span. Distributed loads can be assymetrical and of any length along the span.

A single-tap is all that is needed to change the end support conditions to quickly switch between fully fixed, fixed/pinned, simply supported, and cantilevers.

  • Single-span beam elastic analysis.
  • Extensive section library.
  • Custom section generator.
  • Level 1 features

User Interface

    The following level 1 features

  • 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.
