Ram Structural System and ASCE 7-16 sections 26.11.2.1 and 26.11.3

If a building is rigid per ASCE 7-16 sections 26.11.2.1 and 26.11.3 (approximate Natural frequency> 1.0) and based on Ram Frame analysis the building is flexible (calculated natural frequency <1.0), can the wind analysis be performed as a rigid building?

RAM Connection Gusset Plate design issue

Rafi Oundjian — Wed, 12 Oct 2016 13:56:26 GMT

Hi
I am trying to design a brace column connection with a base plate. I am using the smart gusset plate option to design in RAM connection. The frame was imported from a design that was completed in RAM frame. I am using a W 10x33 for my column and if I set the base plate dimension to 16"x16" the design is being reported as inadequate and it cites section DG1 B.4.1 and it requires the dimension to 15.73"x26.22". I checked the code and it requires the 15.73x13.96 (bf +2*3). Am I missing something here? Is there an actual bug in the code?
