The following design criteria shall be used for SMF and IMF designed and prequalified with AISC 358-16 and AISC 341-16 Seismic Provisions for rolled or built-up I-shaped sections (i.e., wide flange shapes): 1. The appropriate response modification coefficient, R, system overstrength factor, Ωo, and the deflection amplification factor, C

Sections 9.2b (SMF) and 10.2b (IMF) of ANSI/AISC 341 (the AISC Seismic Provisions) provide four options for deter-mining the suitability of a particular moment connection for use in an SMF or IMF: 1. Project-specific testing can be performed according to the requirements in Appendix S of the AISC Seis-mic Provisions. Generally, this option is ...

AISC 358-05 currently provides three prequalified configurations of steel special (SMF) and intermediate moment-resisting frames (IMF). The reduced beam section (RBS), bolted unstiffened extended end-plate (BUEEP) and bolted stiffened extended end-plate (BSEEP) connections are considered as prequalified for SMF and IMF applications, subject to the

A Bolted Flange Plate moment connection may be defined in RISAConnection as the "BFP" Seismic System within the Column/Beam Flange Plate Moment Connection. Depending on the ductility of your system, you may assign the BFP as an OMF, IMF, or SMF.

Effects of JPZ shear distortion: Local buckling in the beam and column flanges due to excessive distortion of the JPZ. This can lead to fracture of the CJP groove welds due to the high strains and increased story drift leading to more damage, greater susceptibility to P-Δ effects and large permanent offsets of building frames.

In order to export a seismic connection, you must do the following: Assign the connection with a Seismic Design Rule in RISA-3D. This defines what level of ductility (OMF, IMF, SMF, OCBF, SCBF) will define your connection and, if it is a seismic moment connection, which predesignated type (RBS, WUF-W, BFP, BEEP, etc.) it shall be designed as.

2018年9月3日 · As the theoretical framework of the BFP Bolted Flange Plate pre-qualified connection is better known, it will be better designed. Consequently, in this paper it is presented in some detail this...

AISG DG4 is used and. The column beam moment ratio requirement applys to SMF connection only. It's OMF connection, so the column beam moment ratio check is not required. Refer to AISC 358-10 6.10 commentary on page 9.2-139. The Design Procedure is very similar to that in.

The connection types listed in Table 2.1 are prequalified for use in connecting beams to column flanges in special moment frames (SMF) and intermediate moment frames (IMF) within the limitations specified in this Standard.
