Known Bugs & Limitations RC

[2/16/2011] Toggling of base reinforcement to YES and NO in Base Rebar input window
If base rebar is included in a model and the user wants to disregard the base rebar by selecting “NO” in the base rebar input screen, the program will still consider the base rebar unless “OK” is selected and then “Next.”  The same is true if base rebar is turned off and you select “YES” to activate it.  In this condition, base rebar will not be considered unless “OK” and “Next” are selected.

[8/11/2010] ADAPT-RC 2010 Investigative Option 2, “Investigate capacity and compare with design loading”
When Option 2 is used as the investigative mode, the output report from Report Generator (Section 33 of the report) will only show data for the moment capacity.  It is recommended to use Option 3 and overwrite the input moments if required.  The full output report will be generated for this option.

[8/11/2010] User-defined rebar in the investigative mode of ADAPT-RC 2010 NOTE: This is a limitation of the program, not a bug
In ADAPT-RC 2010 when a user defines or overwrites reinforcement generated from required or provided in the investigative mode, this rebar is not saved if you close and open the same file.  It must be input each time a new instance of the saved model is opened.  This has been reported to our development team and will be implemented as a improvement in a future release.

[7/7/2010] ADAPT-RC 2010 HELP menus
In ADAPT-RC 2010, the HELP>Contents menu does not appear when pressing it.  As a workaround, their are two HELP files located in the program files directory.  You can copy these files to any location and access the HELP contents from double-clickin on these files.  They are “RCinput.CHM” and “RCshell.CHM.”

[6/16/2010] Cracking moment of inertia, Icr calculated incorrectly at supports (applies to RC5 only, this has been fixed for RC 2010)
ADAPT-RC5 calculates Icr incorrectly  at supports for flanged beams where tension is at the top fiber and the compression zone is in the beam stem.  This results in reported deflection that is less conservative.  This has been modified for the upcoming release of RC 2010.

[5/6/2010] Rebar area incorrect for Investigation Mode when MKS unit system used (Bug 3833)
In the investigation mode of ADAPT-RC 2010, when a user enters reinforcement area based on “Provided Rebar,” the area of steel is entered in cm^2.  This is incorrect and will lead to erroneous investigation results.  The workaround is to use the “Required Rebar” option.

[3/19/2010] Minimum Reinforcement in ADAPT-RC v2010
When drop caps/panels or transverse beams are modeled in ADAPT-RC, the program considers the following:

Two-Way Slabs

(a) In the direction of span, if the drop or transverse beam dimension from support centerline to either side of support is greater than or equal to L/6, where ‘L’ is span length, the program will calculate minimum rebar based on the depth of drop or transverse beam.

(b) In the direction of span, if the drop or transverse beam dimension from support centerline to either side of support is less than L/6,  the program will calculate minimum rebar based on the depth of slab.

One-Way Slabs

(a) In the direction of span, if the transvers beam dimension from support centerline to either side of support is greater than or equal to L/6, where ‘L’ is span length, the program will calculate minimum rebar based on the depth of transverse beam.

(b) In the direction of span, if the transverse beam  dimension from support centerline to either side of support is less than L/6,  the program will calculate minimum rebar based on the depth of slab.

Note:  This is the intended behavior of the program and is not a program bug.
