Abstract: A bracket assembly for interconnecting support struts of the framework of a domical structure such as a geodesic dome. The bracket assembly includes a central annular hub member and a bracket member for interconnecting each of a plurality of circumferentially arranged and radially extending struts to the hub member. The outer end of each bracket member includes a pair of spaced apart side members which straddle the strut and are mounted to the strut by a pair of bolts. The inner end of each bracket member includes a pair of axially spaced apart triangularly shaped bosses located on opposite ends of the hub which are mounted to the hub by a bolt extending through both bosses at a location spaced radially inwardly of the hub member.
