Following the provisions of AISC 342-22 and referencing ASCE 41-17 where needed, I am trying to develop force-deformation relations for a modern RBS connection properly designed and detailed per AISC 341. The curve should be Type 1 in AISC 342 Fig. C1.1 (below) or ASCE 41 Fig. 7-4 since the connection ...

ASCE 41-17 Section 9.4.2.4.3, paragraph 4, states that the acceptance criteria for FR beam-column connections shall be modified based on four possible factors (continuity plate detailing, panel zone strength, span-to-depth ratio, and beam flange & web compactness). I am performing a nonlinear analysis ...

ASCE 41-17 permits the use of the generalized force-deformation relation for deformation-controlled steel elements depicted in Figure 9-2 using the modeling parameters and acceptance criteria specified in Table 9.7-1 for nonlinear procedures. The yield point, Qy, for flexural action in beams is determined ...

ASCE 7-16 (and 7-22) section 12.9.1.4.2 states that, if the MRSA drift base shear is < Cs*W where Cs is determined in accordance with Eq. 12.8-6 (or 12.8-7 in ASCE 7-22), then the MRSA drifts are scaled up by Cs*W / Vt. There seem to be two interpretations of this provision: (a) scale up to Eq. 12.8-6 ...
