Any check which fails to comply the provisions of the relevant codes in Staad Analysis, if not highlighted in the output in a conspicuous manner and unfortunately overlooked by the user, could be fatal. While Staad output highlights the messages and warnings in different colours, it totally ignores the Failed Checks. I have communicated the issue to the technical team via "Case CS0747486" - FAILED Irregularity not Highlighted in STAAD Output.
Attaching one such instance.
Thnak you for posting this idea. As I am sure you are aware, there is anew version of the IS 1893 in the works and due to be published shortly. It was previously published and then withdrawn again. This will be considered when we delivering the new IS 1893.
