Re: Steel straps on wood shear walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
2008 SDPWS section 4.4.1.4 states “Where windows and doors interrupt wood structural panel sheathing or siding, framing anchors or connectors shall be provided to resist and transfer the appropriate uplift loads around the opening and into the foundation.”

Also the combined shear and wind uplift resisting system using sheathing still must comply with all requirements in section 4.3 including section 4.3.6.4.2 which states “Uplift Anchorage at Shear Wall Ends: Where the dead load stabilizing moment is not sufficient to prevent uplift due to overturning moments on the wall (from 4.3.6.1.1 or 4.3.6.1.2), an anchoring device shall be provided at the end of each shear wall.”
