LESSON-4 Flashcards
(13 cards)
Any structure usually enclosed by walls and a roof, constructed to provide support or
shelter for an intended use or occupancy.
BUILDINGS
refers to the
load-resisting sub-system of a building or object.
STRUCTURAL SYSTEMS
A structural system without a
complete vertical load- carrying space
frame.
BEARING WALL SYSTEM
A structural system with an essentially complete space frame providing support for
gravity loads. Resistance to lateral load is provided by shear walls or braced frames.
BUILDING FRAME SYSTEM
A frame not meeting special detailing requirements for ductile behavior. These provide the least resistance to lateral motion and so are only recommended for zero/low seismic
regions.
Ordinary Moment-Resisting Frame System
A structural system with an essentially complete space frame providing support for gravity loads. Wherein the lateral load is primarily resisted by flexural actions of members at the
joints.
MOMENT-RESISTING FRAME SYSTEM
A frame designed in accordance with Section 412 (concrete diaphragm) Designed to resist limited inelastic deformations as the result of lateral forces.
Intermediate Moment-Resisting Frame System
DIFFERENT TYPES OF MOMENT-RESISTING FRAME SYSTEM
- Ordinary Moment-Resisting Frame System (OMRFS)
- Intermediate Moment-Resisting Frame System (IMRFS)
- Special Moment-Resisting Frame System (SMRFS)
Moment resisting frame specially detailed to provide ductile behavior.
Special Moment-Resisting Frame System
An essentially complete space frame that provides support for gravity loads.
DUAL SYSTEM
Similar to the dual system but includes intermediate moment-resisting frames between the
primary lateral load-resisting systems (typically shear walls or braced frames).
DUAL SYSTEM WITH INTERMEDIATE RESISTING FRAME
A structural System relying on cantilevered column elements for lateral resistance.
CANTILEVERED COLUMN FRAMING SYSTEM
A combination of moment-resisting frames and shear walls. The shear wall or braced
frame resist earthquake forces based on their relative rigidities
SHEAR-WALL INTERACTION SYSTEM
