Dear Osdag user,

As per the (upcoming) revised IS 808, NPB sections have been categorized as beam sections. Since Osdag follows the IS code in its development, it has listed the NPB sections under the beam section drop-down menu in the modules.

Typically, NPB sections are used as beams, but in some design scenarios they could be used as a column. For this, you can define the desired NPB section into the Osdag database under the column sections table. The custom section can be defined by using the Design Preference feature of Osdag. Once defined and saved, the custom section should readily appear under the column section drop-down menu. Further, the design process remains the same.

Thank you!
