The load cases construction always use traction control. Also note that the search lines never been used for the case of static loading, nonlinear in the control unit, only for the case of loading under force control. Note that the search lines never been used for the case load just use the step event, that is already off the loop. When you open existing models from the previous version, the case load has enabled both options will turn off the search mode line to reproduce the earlier behavior. By default, the events and repeated no line search will be enabled for the case download new is created, equivalent to the earlier behavior.

Now, when both options are selected, the step event will be used for the first iteration and line search will be used for the subsequent iteration. Ago only one of these two options can be used for case download certain and step events are priority. Static analysis non-linear, includes built in stages, has been enhanced to allow search line use, and step events at the same time. Finally, the new formula support step event, which can be used as part of the strategy loop, and steps are specified for the case of load time history direct integration non-linear integration and nonlinear. Similar changes were made for the recipe of the link element isolation pendulum and pendulum in the previous version of the software.

Some differences in results can be expected due to the new formula, in particular with respect to the sample stiffness originally specified for the isolator is small. Moreover, the pattern of friction has been changed from recipe Wen ago that expresses the gradual transition between the paste and slide to model parallel line express the sudden conversion. The new results will be more accurate in case of observed significant difference between results of old and new. The models shown behavior convergence is slow in the previous version should be running again in the new version to verify results. Those interesting new improvements have been implemented in SAP2000 v21 related to Download, analysis and design. Download CSI SAP2000 Ultimate 24 - Static analysis non-linear, includes built in stages, has been enhanced to allow the search lines used CSI SAP2000 Ultimate:ĬSI SAP2000 is glad to announce the availability of version SAP2000 21.0.2.
