You are constructing a two-story wood frame house in Los Angeles (Seismic Design Category D). The building inspector notes that your shear wall hold-down anchors do not meet seismic requirements. Which CBC provision most likely applies to this situation?
Correct Answer
A) Hold-down connections must resist calculated uplift forces with a safety factor
In Seismic Design Category D, hold-down connections must be designed to resist calculated uplift forces with appropriate safety factors to prevent overturning during seismic events.
Why This Is the Correct Answer
