RCDC CONNECT Edition V11 Update 1
- Addition of Pile-cap deign in Australian code - AS 3600:2018.
Design of Pile-cap as per AS 3600 : 2018 is now available as general availability. User can now design the pile-cap with all available pile configurations in RCDC.
- Addition of Tapered and Stepped type wall in the Tank structure module.
In RCDC 11 tank walls with uniform wall thickness could be designed. In this release, design of tapered and stepped (up to 3 steps) walls can be designed. For Stepped wall, if the wall consists of multiple parametric surfaces one above the other with different thickness in the analysis model, then wall will be identified as stepped wall. Design will be performed as per the available thickness at various section locations for both the walls. User can change the definition of wall with uniform thickness (in analysis model) to 'Tapered' in RCDC and set thickness at Bottom and top of wall. Design calculation, drawings and all other reports will be available for new types of walls.
- Exporting Tank wall geometry and reinforcement data to ISM.
Option is now available to user to export tank wall, tank slab, columns, and beams geometry with reinforcement data to ISM.

Previously a value of 1.0 was always used.
666181 Other Workflows - The routine that is used by the ribbon action in the Steel Connection Design workflow that selects the Beam-Splice Joints has been updated to ensure that if there are beams which do not have webs that are parallel, these will not be identified. Previously if such joints were detected, this would cause the program to terminate. (This issue was addressed in V22 Update 7, but not documented)
668054 Generic GUI Updates - It has been reported that the display of a model has in some unspecified cases the computer attempted to access data elements that were not present. The lack of presence resulting in the application crashing. The GUI has been modified to first test for the data prior to access and thus will prevent the crash from occurring.
669073 Analysis/Design Engine - The AISC 360-16 steel design routine has been modified to ensure that when calculating the torsional or flexural-torsional elastic buckling stress Fe according to clause E-4, the warping constant, Cw, is now omitted (set to zero) for Tee and double angle profiles.

698415 Analytical Modeling Workflow - The management of material data during a session has been updated. When saving a file, data relating to a material which had not been assigned to the model would be cleared from the system memory. However, it would still be displayed in the GUI and if assigned, would cause the application to crash. This is now addressed and materials listed but un-assigned after saving the file can be used as intended.
702092 Analytical Modeling Workflow - The loading routine that is used to define wind loads to the Chinese wind load GB5009 has been updated such that if the definition dialog is opened to specify the details, the underlying dialog which displays the wind profile Intensity/Height data is locked and cannot be closed. Previously, it was possible to close this dialog with the definition dialog open which would cause the application to crash.
702871 Other Workflows - The management of windows in the Steel Connection Design Workflow has been modified to prevent all windows from being closed, and effectively closing the model. In the Results layout that means that it is no longer possible to close the connection drawing window.

707329 Analysis/Design Engine - The steel design routine for members to the Eurocode EN 1993-1-1 has been updated to ensure that for when the check/select design command has a list of members that include multiple tee profiles, the section properties for each of the tee profiles are determined based on the position its own neutral axis.
708118 Other Workflows - The Chinese steel design routine which determined the values of Ky1, Ky2, Kz1 and Kz2 for columns. When set to FIXED BUT, these should be set to 0. Additionally if specified as a secondary member and is a cantilever, this calculation would cause a crash during the design which has now been rectified.
708590 Generic GUI Updates - The routine used to process the initial setting up of the ribbon bar has been updated to address an issue which caused the application to terminate if the ribbon was set as minimised when the application was previously closed.
710597 Analysis/Design Engine - The European steel design to EN 1993-1-1 has been updated for designing slender tee sections. The method used previously was incorrectly determining the major axis term when solving equation 6.62, for bi-axial bending interaction, which could overestimate the profile capacity.
714541 Other Workflows - The option Group Optimization option in the design routine for the Chinese steel design code has been updated to ensure that all the members in a parameter set that has the 'Design Optimisation' checked , and are also part of a group definition will be optimised so that all the members end up with the same profile. Note that if a member is in multiple groups, then the last group it is defined in is used in this operation.
715894 Other Workflows - The Chinese Steel Design workflow has been updated such that when an optimized design has been performed and the action to 'Apply Optimized Results' has been assigned, then not only will the profiles be assigned to the members in the STD file and a new analysis performed, but upon completion, the design will be performed to show the resultant effect of the new profile and analysis results.
716046 Analysis/Design Engine - The Eurocode steel design, EN1993-1-1, for tee sections with slender webs has been updated to ensure the design properties are calculated accounting for the shift in neutral axis and thus reducing the effective moment of inertia.
716322 Other Workflows - The Summary Results Table in the Chinese Steel Design workflow has been updated to better handle sorting the rows by clicking on the column heading.
720077 Other Workflows - The Chinese steel design routine that performs optimisation, when specified, has been updated to allow the inclusion of tapered members, both wide flange and tubes, in the parameter set. Previously their inclusion would cause the program to crash.
