Seismic loading on retaining walls per the Mononobe-Okabe formulation
Analysis Features
Automatic meshing of slabs into well formed quadrilateral elements (NO triangular elements are created by the mesher). This is all done “behind the scenes” without any user interaction necessary, though user may optionally control the size of the mesh
Physical member used for grade beams, automatic inclusion of internally generated mesh points
Soil spring stiffness automatically calculated based on soil subgrade modulus and slab tributary area
Ability to include passive pressure and soil overburden in slab analysis
Self weight of slabs and beams is automatically calculated and may be optionally excluded in the analysis
Point loads, point moments, line loads and area/patch loads can be applied anywhere on the slab
Include Response Spectra Analysis results from RISA-3D model
Result Features
Color contouring of the slabs based on: Transverse shears, Bending moments, Displacements, and Soil pressure
Tabular and graphical display of design results
Slab deflected shape plotting and animation
Line cut tool shows the distribution of moments and shears in the slab at any location, in any direction, simply by drawing a line
Comprehensive grade beam detail reports with force and detail design calculations and expanded diagrams
Ability to exclude results based on selection
Rebar detailing for slab and beam design
Graphical display of total moments/shears for a design strip
Spreadsheet results with sorting and filtering of all output
Rebar schedule and DXF export
Increased solution speed utilizing multithreading
Graphics Features
Unlimited simultaneous model view windows
“True to scale” rendering with translucency, even when drawing
High-speed redraw algorithm for instant refreshing
Dynamically zoom, pan, rotate, scroll, snap views
Font and color control
Saved views to quickly restore frequent or desired views
Saved selections to quickly recall desired selection states
Rendered or wire-frame animations of deflected model
Distance tool for measuring between points
Integrated Structural Design
RISAFoundation is a complete foundation solution and operates independently or fully integrated with RISA-3D and RISAFloor.
RISA-3D, RISAFloor and RISAFoundation are so tightly integrated that they operate as one program on the same building model. Optimize the gravity system in RISAFloor, the lateral system in RISA-3D and the foundation system in RISAFoundation, with a complete flow of information both ways.
Integration support for the following versions: RISA-3D v22, RISAFloor v18, RISAFoundation v16 and RISAConnection v14
All reactions are automatically imported into RISAFoundation for design and detailing of the complete foundation system.
