CASA Space Frame S 21.05

This application offers a comprehensive solution for the static elastic analysis of general 3D space frames within structural and civil engineering. It is particularly suited for students and professionals seeking an accessible yet robust analysis tool, serving as a natural progression from 2D structural software and educational platforms like Intuition.

CASA SF-S enables users to construct detailed 3D models of space frame structures and obtain both numerical results and visual representations of deflections and internal forces. The software emphasizes efficient, precise modelling through an intuitive graphical interface, allowing interactive exploration of results with dynamic displays of numerical data at any member point.

Further information about this application can be accessed via its integrated help system and the official website. Additionally, the app includes "Replay Demonstrations" that illustrate its functionalities through guided visualisations.

Technical features include:

• Automated structural analysis process.
• An extensive section library supporting multiple international standards:
  • British, European, American, Canadian, Australian, South African, Japanese, Russian.
• A built-in section generator for common geometries such as I/H beams, channels, Zed sections, angles, tees (both open and hollow forms), as well as solid shapes in oval and rectangular profiles. Calculates properties including area, moments of inertia, torsional constants, elastic moduli, and mass.
• A comprehensive material library featuring steel, aluminium, concrete, timber, and glass materials, with the option for users to add custom materials.
• Flexibility in member end conditions: rigid or pinned connections.
• Application of loads as points, couples, or trapezoidal loads.
• Support for multiple load cases with combined gravity (self-weight) effects and factored load combinations.
• Results presentation encompasses reactions, deflections, bending moments, shear forces, and stresses—available both graphically and numerically along the entire length of members.

User interface features encompass:

• Compatibility with iPhone, iPod touch, and iPad platforms.
• Support for metric and imperial units.
• Four streamlined interactive screens dedicated to geometry creation/editing, loading configuration, viewing results, and auxiliary utilities.
• Intuitive modelling capabilities such as node selection and editing via tap; geometry movement; length adjustments; member splitting; load replication; direct manipulation of model components through gestures (rotate, pan, zoom).
• Interactive tools allowing drag-and-drop control over node positions, load magnitudes and locations, as well as result readouts along members by dragging markers.
• The ability to tap on points of interest for detailed data retrieval, measuring distances, angles between nodes, or areas defined by selected points.
• Numeric input mode accessible through double-tap actions complemented by an integrated calculator tool.
• A straightforward section library enabling selection based on country standards and geometrical shape; visual diagrams and property data are displayed immediately; custom shapes can be edited double-tap style. Axial axes are rotatable in 90-degree increments.
• Customisable report generation featuring layout control; previews are available on-screen with export options including PDF emailing and AirPrint support.
• Additional utilities such as document titling; unit system selection; online help access; options for loading, saving, and exporting models to facilitate workflow integration.
