CSI SAP2000 Ultimate 21 – The program offers you a highly sophisticated, intuitive and versatile user interface based on an unrivaled analysis engine and design tools for engineers working in the field of transportation, industry, sports and more. SAP2000 has proven itself as the most integrated, productive and practical general-purpose structural program on the market, from a graphical modeling environment based on 3D objects to a wide range of analysis and design options fully integrated into a single powerful user interface.

This intuitive interface allows you to quickly and intuitively create structural models without long learning curves. Now you can use the program’s capabilities to perform all your analysis and design tasks, including small everyday tasks.

The models showing the slow behavior coincidence in the previous version should be re-run in the new version to verify the results. The new results will be more accurate in case there is a significant difference between the old and new results. In addition, the friction model has been changed from the recipe of Wen back, which reflects the gradual transition between the paste and slide model of the parallel line express-sudden transformation.

Some differences in the results can be expected due to the new formula, in particular with respect to the sample stiffness originally specified in the isolator is small. Similar changes were made for the recipe for the connection of the pendulum and pendulum isolation elements in the previous version of the software. Finally, the new formula supports the step events, which can be used as part of the strategy cycle and the steps are specified for the case of load time direct integration of nonlinear integration and nonlinear.

Static nonlinear analysis, includes built-in stages has been expanded to allow search string and step events to be used simultaneously. Previously only one of these two options could be used to load a specific event and step are the priority. Now when both options are selected, the step event will be used for the first iteration and the search string will be used for the subsequent iteration. By default, repeat events and no search string will be enabled in the case of a download created a new, equivalent to the previous behavior. When opening existing models from previous versions, in the case of load enabled both options will turn off the search mode to reproduce the previous behavior.
