[mark_p]

program appears to be checking web slenderness of a double symmetrical I section to yeild limit of 130.  but the standard states this should be increased to 180 in this case.

Hi Mark,

Thank you for your question.

There is a bug as RSA uses rules taken from Australian standard without taking into account differences introduced by New Zeeland standard.

New Zeeland NZ3404 is almost the copy of Australian AS4100. 

In case of slenderness limits used for section classification the table 5.2 (NZ3404) is almost the same as limits given in table 5,2 (AS4100) with one exception in line 4 provided by Amendment 1 (June 01) to NZ3404 that changes the limits for bent webs (compression at one edge - tension at the other).

Australian limits (82,115) for any type of section 

were replaced by the rules specified separately for 

• I sections in bending according strong axis (82,180)
• rectangular and square hollow sections (45,60) - very strong reduction in comparison with previous rules !
• In all other cases (82,130)

I have registered the issue in our database to be fixed in the future.

Best regards,

Pawel

Just checking is there a likely time line to this, and how will we be notified - updated.

Hi Mark,

This issue is a high priority for us, and we are actively working on it. However, it is challenging to provide an exact timeline for the release of the service pack at this moment.

Rest assured - all RSA users will be automatically notified as soon as the new version becomes available for installation

Hope it helps,

Pawel
