RCDC (SACD) Connect Edition V11 Update 3.1 (11.03.01.010)

The following defects are resolved in RCDC CONNECT Edition V11 Update 3.1,
1.Ductile Column design - Error in the calculation of Issue in the final design of main reinforcement while performing various redesign operations.
For columns that are designed using the Auto Design facility, RCDC allows some further redesign operations to be performed on those columns. Examples of these redesign operations are:
a) Level Grouping - which allows all the columns at a given level to have the same reinforcement
b) Level Ungrouping - which is the opposite of what is described in (a) above
c) Grouping of any two or more columns specifically chosen for this task
d) Un-grouping of any two or more previously grouped columns specifically chosen for this task
e) Grouping/un-grouping using the Snapshots facility available in the Reports menu of RCDC
f) An ignore/include operation is performed for some columns
An error is present in the reinforcement that is calculated for ductile columns that are subjected to the afore-mentioned redesign operations if the user performs the following steps in the sequence described
i) Performs Auto-design
ii) Closes the file
iii) Re-opens the file
iv) Performs one or more of the redesign operations described in (a) through (f) above.
The error is in the calculation of the main reinforcement of the column. There are chances that the final reinforcement calculated would be lesser than the required reinforcement.
This issue has been resolved in RCDC V11 Update 3.1. The correct design is now performed for the various redesign operations. The provided value of the reinforcement calculated for the above various redesign operations now satisfies the steel area required to resist the loads.
2.Column design - ACI 318 (FPS unit codes) - Issue in length parameters on redesign Screen for grouped columns/walls.
For the ACI 318-2011, ACI 318-2014, and ACI 318-2019 (FPS unit codes) there was an error in displaying the length parameters on the redesign screen for the grouped column/walls. The values of the unsupported length and effective length factor shown on the redesign screen for grouped columns/walls were not consistent with the values calculated during auto design or values provided by the user.
This error too has been resolved in the RCDC V11 Update 3.1 release. The correct unsupported length and effective length factor values are now shown on the redesign screen which should enable the user to perform the redesign operations.
