spMats Features

Technical Features

  • Support for ACI 318-14/11/08/05/02 & CSA A23.3-14/04/94 design standards
  • Four-noded prismatic thin plate element with three degrees-of-freedom per node
  • Material properties (concrete and reinforcing steel) may vary from element to element
  • Soil may be applied uniform over elements or concentrated applied at nodes using nodal spring supports
  • Nodes may be restrained for vertical displacement and/or rotation about X and Y
  • Nodes may be slaved to share the same displacement and/or rotation
  • Loads may be uniform (vertical force per unit area) or concentrated (Pz, Mx, and My)
  • Load combinations are categorized into service (serviceability) and ultimate (design) levels
  • The self weight of the slab is automatically computed and may optionally be included in the analysis
  • Result envelopes (maximum and minimum values) for deflections, pressures, and moments
  • Design moments include torsional moments contribution
  • Punching shear calculations for rectangular and circular columns

Program Features

  • Export of mat plan to DXF files for easier integration with drafting and modeling software
  • Export of column and/or pile sections as CTI file to be analyzed by spColumn
  • Import of grid, load, and load combination information from text files to facilitate model generation
  • Automatic internal node and element numbering
  • Fast graphical interface that displays the modeled mesh at all times for verification
  • Graphical image displaying node and element numbers, grid lines, and slab boundaries
  • Ability to zoom and translate (pan) the graphical image
  • Isometric (3D) view of the modeled slab with ability to rotate using the mouse
  • Contour plots to visualize results of analysis and design
  • 255 X & Y grid lines
  • 255 Thickness definitions
  • 255 Concrete definitions
  • 255 Soil definitions
  • 255 Nodal spring definitions
  • 255 Slaved nodes definitions
  • 255 Pile definitions
  • 255 Concentrated load definitions per load case
  • 255 Surface load definitions per load case
  • 255 Load combinations
  • Approximately 65,025 nodes and 64,516 elements

General Features

  • English (in.-lb) or SI (metric) units
