ABSTRACT:
A method for constructing a suspension bridge in places where it is not feasible to construct permanent earth anchorages land at either or both ends of the suspension bridge span is disclosed. The method of constructing the self-anchored suspension bridge comprises the use of preexisting permanent structures solely or in combination with minimum temporary structures to provide temporary anchor points for main suspension cables during construction. Once the suspension bridge span end structures are properly secured by a tensioning cable to the temporary structure or by a temporary connection to a permanent structure and the deck segment of pier table is lifted into place and tied down on an end support, the main suspension bridge cables are erected, suspenders are then erected from the main cable, and further construction of the bridge proceeds. Once the bridge deck segments are all erected and integrated with the end piers, temporary PT bars or cables connecting end supports to either preexisting or temporary structures are gradually released to transfer anchoring force back to the bridge deck. The temporary PT bars, cables and the temporary structures (if used) are then disassembled and removed.
