Abstract

A portal frame comprising of a pair of columns (18A, 18B) and a pair of rafters (20A, 20B) is disclosed. The rafters (20A, 20B) and columns (18A, 18B) are each of a closed hollow section. An apex connector (24) to which one end of both of the rafters (20A, 20B) is connected, and a pair of knee connectors (26A, 26B), wherein each is configured to connect to an opposite end of one of the rafters (20A, 20B) and one end of one of the columns (18A, 18B) thereby forming the portal frame. The apex and the knee connectors (26A, 26B) are designed whereby plastic failure of the portal frame can occur under a specified design criterion wherein plastic hinges are formed in the columns (18A, 18B) and rafters (20A, 20B) before failure can occur in the connectors. The apex connector (24) and the knee connector comprises of an internal sleeve having opposite ends adapted to slide within the corresponding column or rafter. Further there is an external sleeve formed about and intermediate section of the internal sleeve, wherein the internal and external sleeves together provide a moment connection whereby plastic failure of the portal frame occurs within the columns (18A, 18B) and/or rafters (20A, 20B) remote from the connectors.
