lateral forces-resisting system

A lateral force-resisting system (LFRS) is a structural system designed to resist horizontal forces acting on a building or structure, such as those caused by wind, earthquakes, or other lateral loads. The LFRS ensures the structure remains stable by transferring these forces to the ground, preventing excessive deformation or collapse. Common types of LFRS include:
• Shear walls: Vertical walls that resist lateral forces by providing stiffness and strength.
• Braced frames: Frameworks with diagonal braces that resist lateral loads through tension and compression.
• Moment-resisting frames: Structural frames designed to resist lateral forces through rigid connections that allow bending resistance.
• Diaphragms: Horizontal elements (e.g., floors or roofs) that distribute lateral forces to vertical elements like walls or frames.
The specific LFRS used depends on the building’s design, materials, and the expected magnitude of lateral forces based on location and building codes.

Agree, how where in the BC does section 606.2.2 tie to, there is no definition IEBC, IBC or body of the codes that i can find uses the term lateral forces-resisting system.

201.3​

Where terms are not defined in this code and are defined in the other International Codes, such terms shall have the meanings ascribed to them in those codes.

[BS]NOMINAL LOADS. The magnitudes of the loads specified in Chapter 16 (dead, live, soil, wind, snow, rain, flood and earthquake).

[BS]LOAD AND RESISTANCE FACTOR DESIGN (LRFD). A method of proportioning structural members and their connections using load and resistance factors such that no applicable limit state is reached when the structure is subjected to appropriate load combinations. The term “LRFD” is used in the design of steel and wood structures.

structural members and their connections is the LFRS.
