Magnitude10 Soft Story Brace Installed in 3 Hours (extended version)

Описание: "Extended version" timelapse of a 700-pound Magnitude10 brace installation to protect a "soft story" apartment building in Oakland from collapse during an earthquake.

This video includes the whole installation process, including hoisting the brace off of the delivery truck and driving 106 screws to secure the brace to the building structure. Shot at 30x speed; thus 1 minute of video represents 30 minutes. This demonstration was also filmed professionally; breaks in the installation to direct and reposition the production equipment are cut out of this timelapse.

This installation includes only the Magnitude10 brace itself. A trench for the new footing was already dug. Likewise, the "collector" (running behind the original beam spanning the carport openings) was already installed. These components are needed for virtually any retrofit method--they are not an additional requirement for the Magnitude10 brace.

One Magnitude10 brace is sufficient to brace this apartment building to comply with Oakland's mandatory soft story retrofit ordinance. Fitting the Magnitude10 brace into an existing building is much easier than installing a traditional steel frame.

The quick installation process means less inconvenience for tenants. No welding is needed, eliminating scheduling another trade and the associated fire hazard and toxic fumes.

The engineering properties of the Magnitude10 brace (as supported by an internationally recognized Code Evaluation Report) allow for more efficient designs. This means the necessary footing and other components in the entire earthquake retrofit system can be smaller than required for traditional steel frames.
