has a complete space frame system but the space frame providing support to gravity loads.
Building Frame System
Resistance to lateral loads is provided by
shear walls or the braced frame
Building Frame System:
___m height limitation in Zone 4 when using special RC shear walls or braced frames
75
Building Frame System:
___ m height limitation in Zone 4 when using intermediate RC shear walls or braced frames
10
t or F
Building Frame System:
Ordinary RC shear walls or braced frames not permitted for Zone 4
true
A structural system with an essentially complete space frame providing support for gravity loads
also provide resistance to lateral load primarily by flexural action of members
Moment Resisting Frame
t or f
Moment Resisting Frame:
No height limitation in Zone 4 when using special RC moment-resisting frames; intermediate and ordinary RC moment-resisting frames not permitted for Zone 4
true
Moment Resisting Frames may be classified as:
a) Special Moment Resisting Frames (SMRF)
b) Intermediate Moment Resisting Frames (IMRF)
c) Ordinary Moment Resisting Frames (OMRF)
Expected to withstand limited inelastic deformations
Doesn’t require use of prequalified connections per AISC
Not required to be tested
typically used in non/low-seismic regions
OMF
Expected to withstand moderate inelastic deformations
Require use of prequalified connections per AISC
Must sustain inter-story drift angle of a least 0.02 radians
typically used in low/mid-seismic regions
IMF
Expected to withstand significant inelastic deformations
Require use of prequalified connections per AISC or verified with testing
Must sustain inter-story drift angle of a least 0.04 radians
typically used in mid/high-seismic regions
SMF
