Deployable structural units and systems

摘要

Deployable units and systems made of deployable units are described. The units have a retractable brace transitioning from a retracted condition to a deployed condition through a gravity driven movement, a latching arrangement contacting the brace and keeping the brace in position when the brace is in the deployed condition, and a guiding arrangement to guide the movement of the brace. The systems comprise plural deployable units to be arranged in a building structure, each unit to be located in a respective bay per story space of the building structure.

1. A deployable unit configured to assume a retracted condition and a deployed condition, comprising:
a retractable brace having a retracted condition and a deployed condition, wherein transition from the retracted condition to the deployed condition occurs through gravity driven movement of the brace; a latching arrangement, the latching arrangement contacting the brace and keeping the brace in position when the brace is in the deployed condition; a guiding arrangement to guide the gravity driven movement of the brace, and a control circuit coupled to the retractable brace, the control circuit configured to receive an early earthquake warning (EEW) signal and to output a release command, the release command triggering the gravity driven movement of the brace from the retracted condition to the deployed condition.
