Blast-resistant building (11) includes a structural connection (10) including at least one layer of fiber reinforced composite (90) bonded to each connected structural element (20,30) along the length of the connection between structural panel (20) and elongate anchoring structures (30), such as I-beam (40) or additional concrete panel (50). Layer of fiber reinforced composite (90) spans peripheral seam (36), internal seam (37), or both between the connected elements, providing a tensile force under load which tends to hold the elements together and to strengthen the connection while simultaneously providing ductility along the seam, lessening the risk of fracture of either element or the connection under atypical loading, such as from a blast. Connection (10) includes an elongate tension member, such as bolt (80), for attaching the various elements, and a force dampener, such as a rubber isolation washer (89), to increase the ductility of the connection. In another embodiment, connection (10) includes an elongate fastener, such as bolt (70), for securing layer (90) to each structural element (20,30) and preventing layer (90) from separating from the surface to which it is bonded under load.
