Definitions

  • a mechanically fused expansion joint system for bridging a gap between spaced-apart, adjacent structural members is provided.
  • the mechanically fused expansion joint system is useful in constructions such as roadway constructions, bridge constructions, and other constructions where it is desirable to accommodate large movements that occur in the vicinity of the expansion joint gap between the structural members.
  • An expansion joint gap is purposefully provided between adjacent structural members for accommodating dimensional changes within the gap occurring as expansion and contraction due to temperature changes, shortening and creep caused by pre-stressing, seismic cycling and vibration, deflections caused by live loads, and longitudinal forces caused by vehicular traffic.
  • Expansion joint systems may be utilized to accommodate the movements in the vicinity of the gap, but still permit flow of traffic across the gap.
  • Roadway and bridge constructions typically are designed to withstand particular maximum movements and forces without damage. As the level of movement and forces to which a construction is designed to endure without damage increases, the expense of the expansion joint design to accommodate the movements and forces increases. High energy events which produce large movement and large forces in these constructions, as a result of seismic activity, tsunamis, bass waves or rogue waves, strong winds, or other activity, are rare and as the energy level of an event increases, the rarity of the event also increases. As such, designs to fully accommodate high movements and minimize damage due to high movements and forces from high energy events can become unreasonably expensive in light of the rarity of these high energy events.
  • the relevant industry still demands a cost-effective expansion joint system to accommodate large movements and forces in expansion joint gaps in response to high energy events, whereby the expansion joint system can effectively mitigate damage from rare large movements and large forces in constructions resulting from high energy events.
  • an expansion joint system for bridging a gap between adjacent structural members, the system comprising a member for bridging a gap between two spaced apart structural members and mechanically fused housings and/or mechanically fused connectors that are designed to break in response to the application of pre-determined loads to the system.
  • the expansion joint system for bridging a gap between spaced-apart structural members comprises a load bearing member bridging said gap; a housing having a fused portion: and a support member positioned below said load bearing member and bridging said gap, said support member at least partially housed within said housing and slidable therein.
  • the expansion joint system for bridging a gap between spaced-apart structural members comprises a load bearing member bridging said gap, wherein said load bearing member is engaged by a mechanically fused connector to a mechanically fused portion of said structural member.
  • FIG. 1 illustrates a side elevational view of one illustrative embodiment of the mechanically fused expansion joint system.
  • FIG. 2 illustrates a side elevational view of another illustrative embodiment of the mechanically fused expansion joint system.
  • FIG. 3 illustrates a side elevational view of another illustrative embodiment of the mechanically fused expansion joint system after the mechanically fused elements have fractured.
  • FIG. 4 illustrates an enlarged side elevational view of a mechanical fuse in one illustrative embodiment of the mechanically fused expansion joint system.
  • FIG. 5 illustrates an enlarged side elevational view of another mechanical fuse in one illustrative embodiment of the mechanically fused expansion joint system.
  • the expansion joint system includes mechanically fused components that are designed to break or otherwise yield in response to the application of loads that exceed design limits for the system.
  • the fused components permit the expansion joint system to break away from the underlying structural members with limited damage to the expansion joint system or the structural members.
  • the expansion joint system may be utilized in roadway, bridge, and tunnel constructions to accommodate large movements in the vicinity of the gap.
  • the expansion joint system may be a modular type, a cover plate type, an interlocking finger type, or any other type. Because the expansion joint system is not damaged, it can be reinstalled to the underlying bridge or roadway structure after the high energy event.
  • a modular type expansion joint system comprises a plurality of transversely extending, spaced-apart, vehicular load bearing members; longitudinal support members positioned below the vehicular load bearing members and extending longitudinally across the expansion joint gap; and a housing for accepting ends of the longitudinal support members for controlling the movement of the ends of said support members. Seals are generally provided between the vehicular load bearing members and between vehicular load bearing members and edge members.
  • the seals may be flexible and compressible and, therefore can stretch and contract in response to movement of the vehicular load bearing members within the expansion joint gap.
  • the seals may be made from a durable and abrasion resistant elastomeric material.
  • the seals are not limited to any particular type of seal. Suitable seals that may be used include, but are not limited to, strip seals, glandular seals, and membrane seals.
  • the housings for accepting ends of the support members may include structures such as, without limitation, boxes, receptacles, chambers, containers, enclosures, channels, tracks, slots, grooves or passages, which include a suitable cavity for accepting the end portions of the support members and permits the desired movement of the support member within the housing.
  • the top wall of the housing may be mechanically fused to provide a break-away portion in response to an emergency high energy condition.
  • Expansion joint systems are designed to accommodate movement of adjacent structural members relative to one another such that, as the gap between the adjacent sections changes in size or shape, traffic may still flow across the gap.
  • the amount of change in the gap which an expansion joint system can accommodate is limited such that there is a minimum gap condition and a maximum gap condition which may occur without causing some damage to the expansion joint system, or the adjacent structure, or both.
  • an operation which closes the gap below the above referenced nominal minimum gap condition or opens the gap beyond the above referenced nominal maximum gap condition will be referred to as an “emergency operation”.
  • Expansion joint systems which comprise mechanically fused elements include elements, assemblies, or both that are designed to break at or above predetermined loads produced by emergency operations. Furthermore, the elements and assemblies are designed to break in specific ways in order to limit damage to the system, its surroundings, and/or to improve system performance predictability.

  • Some materials used in conventional construction have very predicable design characteristics as compared to other materials used in conventional construction.
  • One such material is steel.
  • a designer can specify the shape, material, and installation of a steel component and predict its performance criteria with very high precision.
