Bolted Connections for Steel Towers

Document Type: Proceeding Paper

Part of: Innovations in the Design of Electrical Transmission Structures


Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1) bolts have historically served as the predominant fastener for these structures. Recent changes in this specification provide an opportunity for using higher allowable design values thus reducing the number of bolts required. Recommended values consistent with the new specification are outlined.
