ReCCSA

Features

• Simple, easy to use, graphical user interface
• Fully functioning save/open so that geometry and the corresponding mesh can be saved.
• Analyze rectangular, circular, or custom sections.
• Includes basic prestressing steel. User must enter prestressing material information.
• Includes a custom section builder that allows a section to be defined with points and functions.
• Includes numerous pre-defined material models (both monotonic and cyclic).
• Allows user to enter custom material models using stress/strain relationships. Users can enter values or import from .csv file.
• Runs Axial Force - Moment analysis and Moment - Curvature analysis in ANY analysis direction.
• Moment - Curvature analysis can be run at a defined load state, including an axial force and moments about both axes.
• Runs cyclic Moment - Curvature analyses. These utilize cyclic material models and can be run at varying axial loads.
• Moment - Curvature analysis will bi-linearize the Moment - Curvature diagram and report curvature ductility and overstrength based on effective yield and ultimate values.
• Interactive cross section viewer allows user to cycle through solved points on the Moment - Curvature diagram and view the stress state of the cross section.
• Detailed output can be written at each Moment - Curvature point. This includes information such as location, strain, stress, material, etc., for each element and reinforcement bar.
• Allows the user to save the resulting Axial Force - Moment, Axial Force - Curvature, and Moment - Curvature diagrams to a .csv file so that they may be opened in Excel or other programs.
• Includes a couple of different meshing options and allows user to control the element size.
• Gives the user significant control over iteration parameters. If solutions aren't converging, there are many parameters that can be adjusted to achieve convergence.
• Allows the user to set the limit states of the section by changing the limiting strains in the steel and either the confined or unconfined concrete.
• Provides an option to treat the cross section as completely unconfined, which is useful if analyzing simple concrete beams without true confinement.
• Provides an option to apply ACI-318-05 load reduction factors to the moment reported on the Axial Force - Moment diagram.
• Generates a report that can be printed (alhough the report leaves a lot to be desired).
