  • Hello,

    I further checked the issue and found that the columns here with dimension 150 x750 mm is getting designed as wall. The reason is the settings.

    As per this setting for your column D/B = 750/150 = 5 > 4 and qualify for wall. Now as per BS 8110 1997 code Table 3.23 provides the allowable maximum slenderness ratio. As in your model the slenderness was greater than limiting ratio, it was showing fail. 
    If you want the column not be designed as wall you can put a higher value in the above mentioned field like 6, and will find no such slenderness failure.

    Also, I would like to confirm RCDC can design the columns for slender cases considering additional moments due to slender.
