EXPANSION JOINT SYSTEM USING FLEXIBLE MOMENT CONNECTION AND FRICTION SPRINGS
First Claim
1. An expansion joint system for a gap defined between adjacent first and second structures comprising:
- at least one transversely extending vehicular load bearing member having top surfaces exposed to traffic and bottom surfaces opposite said top surfaces;
at least one support member positioned below said at least one transversely extending load bearing member and extending longitudinally across said expansion joint from said first structure to said second structure; and
at least one flexible moment connection connecting said at least one transversely extending vehicular load bearing member to said at least one support member.

Abstract
An expansion joint system for bridging a gap that is located between spaced-apart structural members. The expansion joint system may be utilized, for example, in roadway, bridge and tunnel constructions where gaps are formed between spaced-apart, adjacent concrete sections. The expansion joint system includes flexible moment connections for connecting vehicle load bearing members to the support member. In certain embodiments, the expansion joint system includes flexible moment connections and friction springs. The expansion joint system may be utilized where it is desirable to absorb loads applied to the expansion joint systems, and to accommodate movements that occur in the vicinity of the expansion joint gap in response to temperature changes, seismic cycling and deflections caused by vehicular loads.
