Abstract: A system for preventing damage to a building or other structure during severe meteorological conditions (high wind) or geological (seismic) activity. The system includes a tiedown bracket for securing a roof or wall panel to an underlying support member, e.g., a truss or joist, and a stud connector for attaching the stud perpendicularly to its support beam. The bracket enwraps three sides of the support member and is gusseted on each side of the support member. The gussets have extension portions which extend through joints between the roof or wall panels and then are bent over to hold down the panels so they bear on the support member. The stud connector engages three sides of a stud support beam and four sides of the stud. The bracket and connector can have particular anchors integral with the plates forming them such that conventional fastening means, e.g., nailing, can be reduced or eliminated.
