SEISMIC STRUCTURAL DEVICE

摘要

A link-fuse joint resists bending moments and shears generated by seismic loading. A joint connection includes a first plate assembly having a first connection plate including a first diagonal slot formed therethrough. A second plate assembly has a second connection plate including a second diagonal slot formed therethrough. The second diagonal slot is diagonally opposed to the first diagonal slot. The second connection plate is position such that at least a portion of the second diagonal slot aligns with a portion of the first diagonal slot. A pin is positioned through the first diagonal slot and the second diagonal slot. The joint connection accommodates a slippage of at least one of the first and second plate assemblies relative to each other when the joint connection is subject to a seismic load and without significant loss of clamping force.
