DESIGN AND ANALYSIS OF CROSS-SECTIONS
With GeoForce One, users can design and analyze reinforced concrete and prestressed concrete. Timber and masonry cross-sections with standard and generic shapes can also be analyzed by the software.
Definition of cross-sections with standard shape (rectangular or circular) through ad-hoc editors | Definition of cross-sections with generic shape by means of an integrated CAD environment | Definition of steel rebars | Definition flexural, shear, confinement and torsional strengthening systems | Definition of reinforced jacketing | Definition of one or multiple load cases
Combined biaxial-bending and axial-force checks: initial state before the application of the strengthening system, SLS, ULS | Confinement, shear and torsion checks: for RC cross-sections, the concrete constitutive model accounts for the confinement effect | Identification of the main features of the software | Checks with one or multiple load cases
VISUALIZATION AND EXPORT OF ANALYSIS RESULTS
Visualization and export of detailed reports | Summary of used materials and strengthening systems | Check results for initial state and SLS | Check results for ULS before and after the application of Kerakoll strengthening systems | Visualization of 2D and 3D interaction domains | Visualization of moment-curvature response
Definition of structural element with ad-hoc editors | Elements are modeled with a variable number of cross-sections and their location along the element axis | Modeling of strengthened ribs for arches and vaults
FEM NONLINEAR STATIC ANALYSIS
Definition of loads and boundary conditions | Static nonlinear analysis in two stages: initial stage (ie. before the application of the strengthening system, under load control) and final stage (with the strengthened structural element, under displacement control) | Beam/Column Finite Element with a fiber cross-section for the numerical integration of the cross-sectional response | Nonlinear constitutive models based on plasticity and continuum damage theories.
VISUALIZATION AND POST-PROCESSING
Visualization of the analysis results of each stage | Visualization of Contour Plots for nodal and elemental results | Visualization of Contour Plots for sectional results: stress and strain in each point of the fiber cross-section, material status (elastic, plastic, damages, cracked, crushed, etc...), usage factors | Load-displacement plot
main features of the pre and postprocessor
Basic and advanced CAD modeling commands for creating and manipulating points, curves, surfaces and solids | Import-export support for common CAD file formats | Choice of external solvers | Python-based interface for extending preprocessor capabilities and generation of user interface objects | Material properties, beam and shell cross-sections, generic attributes, loads, boundary conditions, and analysis algorithms | Generation of the computational mesh of the model
Generate input files | Launch the external solvers | Monitor analyses
Read one or multiple output databases | Prepare simple or composite representations/animations of the results | Contour plots, volume plots, vector plots, streamlines, beam diagrams, etc | Extract tables and graphs from the database | Manipulate the results by means of built-in operations (sum, avarage, envelope, etc..) or custom python-based scripts
Evolution of damage at the peak of resistance
New application for verifications of masonry structures.
