<p>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.</p> |
