WRAPPING AN ARCH IN CONCRETE
A new method called the Concrete Lapping with Pre-erected Composite Arch Method (CLCA) is described, which is being used to construct the Asahi Bridge (in Japan) spanning 190 feet. Before selection of this method of construction, the article describes how the costs and characteristics were completely analyzed. In this method, tubular steel arches are erected first by building half of the arch on each side of the river. The completed steel arch tubes are pumped full of concrete to form a composite arch. This then acts as the falsework and is wraped with reinforced concrete to form the bridge arch. This method would provide a stiff and very stable falsework that would not intrude into the river bed below or require dismantling after construction. The details of designing the bridge and its construction are described.
