Abstract
The present invention is a pin-fuse joint generally utilized in a beam-to-column joint assembly subject to extreme seismic loading. The pin-fuse joint resists bending moments and shears generated by these loads. The joint is comprised of standard structural steel building materials, but may be applied to structures comprised of structural steel, reinforced concrete, and or composite materials, e.g., a combination of structural steel and reinforced concrete. The beam-to-column assembly is comprised of a column and a beam and a plate assembly that extends between the column and the beam. The plate assembly is welded to the column and is attached to the beam via the pin-fuse joint. The pin fuse joint is created by a pin connection through the beam and the connection plates of the plate assembly at the web of the beam. Additionally, both the plate assembly and the beam have curved flange end connectors that sit flush against one another separated only by a brass shim when the beam and plate assembly are joined. The curved flange end connectors of the beam and plate assembly are then secured against one another by torqued high-strength bolts.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
