A swaged interface includes a male element that includes a male cavity defined by at least one male sidewall, and a plurality of first openings defined in the at least one male sidewall. The swaged interface also includes a female element that includes a female cavity defined by at least one female sidewall, and a plurality of second openings defined in the at least one female sidewall. The female element has an inner cross section sized to receive the male element such that each of the first openings is aligned with a respective one of the second openings. The inner cross section is formed by swaging.

Structural support member with swaged female interface

An interface for a structural member includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. The at least one first sidewall defines a female end section and includes a transversely oriented female end surface at the first end. The interface also includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall defines a male end section adjacent the second end and configured to be received within the first cavity, and a stop surface offset longitudinally from the second end and oriented to bear against the female end surface in substantially face-to-face contact when the male end section is received within the female end section. The stop surface and the male end section are integrally formed and monolithic.

Structural support member having a tapered interface

An interface for a structural column includes a female end section that includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. An interior surface of the at least one first sidewall tapers transversely outwardly along the female end section towards the first end. The interface also includes a male end section that includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall is configured to be received within, and oriented in substantially face-to-face adjacent relationship with, the at least one first sidewall. Each of the female end section and the male end section is a respective unitary casting.

An exterior surface of the at least one second sidewall tapers transversely inwardly, complementary to the at least one first sidewall, along the male end section towards the second end.

A cast structural connector connects a structural member, such as a hollow structural section (HSS) or wide flange (W) section member, to a structural frame. The connector is particularly suited for lateral bracing and includes a first end configured to receive the structural member and be welded to the structural member, a second end for connecting to the structural frame, and an intermediate portion. The first end includes beveling allowing compatibility with structural members of varying sizes and enabling complete joint penetration welding thereby developing the full axial strength of the structural member. The intermediate portion provides for transmission of forces as the frame deforms, for example, under severe seismic conditions, and can include a flexural plastic hinge portion. The connector can be welded to the structural frame or connected by a standard fabricated end connection, such as a gusset plate. Casting manufacturing allows for mass production of the connector.

Cast structural connectors

A yielding fuse device is provided for use in association with a brace member in a bracing assembly for a structural frame. The device includes arms or elements that yield flexurally when a bracing member moves in an axial direction, with the bracing assembly under either tension or compression loading conditions. The device of the present invention is particularly useful as a mass customized cast device. The device is well suited for seismic bracing applications.
