Under the California Building Code, what is the minimum required net uplift capacity for a holdown connector at the end of a shear wall designed for 3,000 pounds of overturning moment with a 10-foot wall height?
Correct Answer
A) 3,000 pounds
The net uplift force equals the overturning moment divided by the wall length (distance between holdowns). For a 3,000 pound overturning moment, assuming standard wall proportions, the holdown must resist the full calculated uplift force of 3,000 pounds minimum per CBC Section 2305 and ASCE 7 load combinations.
Why This Is the Correct Answer
The net uplift force equals the overturning moment divided by the wall length (distance between holdowns). For a 3,000 pound overturning moment, assuming standard wall proportions, the holdown must resist the full calculated uplift force of 3,000 pounds minimum per CBC Section 2305 and ASCE 7 load combinations.
