Seismic Design of Reinforced Concrete Special Moment …
nvlpubs.nist.govThese moment-resisting frames are called “special moment frames” because of these additional requirements, which improve the seismic resistance in comparison with less stringently detailed intermediate and ordinary moment frames. The design requirements for special moment frames are
Chapter 11 SEISMIC DESIGN CRITERIA - Memphis
www.ce.memphis.edumembers. Moment frames are categorized as intermediate momentframes(IMF),ordinarymomentframes(OMF),and special moment frames (SMF). Structural System: BuildingFrameSystem:Astructuralsystemwithanessen-tially complete space frame providing support for vertical loads. Seismic force resistance is provided by shear walls …
Seismic Design of Steel Special Moment Frames
www.atcouncil.orgMoment Frames. Design requirements for steel special moment frames are contained in a series of standards. ASCE/SEI 7-05, Minimum Design Loads for Buildings and Other Structures (ASCE 2006), referred hereafter as ASCE 7, sets the basic loading criteria for steel special moment frames together with associated lateral drift limits.

www.aisc.orgfor Rigid Moment Frames resisting Section Properties Wide flange steel section properties can be estimated with reasonable accura-cy when the member depth, width and foot-weight are known. Recalling that the density of steel is 490 pcf, the rela-tionship between cross section area and foot-weight can readily be derived as:
4.5 Procedures for Diaphragms - Memphis
www.ce.memphis.edumoment frames, whereas a metal deck roof is relatively flexible compared to concrete or masonry walls. Wood diaphragms are generally treated as flexible, but consideration must be given to rigidity of the vertical elements. Wood diaphragms may not be flexible compared to wood shear wall panels in a given building. Another consideration is ...

Diagonal bracing members are needed for stability. • Frame B-B is a moment frame, where all members are connected using fix/moment
