Abstract
The concrete arch ribs of the Jōshi Bridge were constructed by a new erection method called the concrete lining method with preerected composite arch (CLCA method). In this method, tubular steel arches are first erected. Next, concrete is filled into the steel tubes to form a composite arch. Finally, the concretefilled steel tubes are used like falsework and are encased in reinforced concrete to form the finished arch rib. Because the composite arch has excellent resistance against axial compression, the amount of steel used can be significantly reduced compared to conventional arch center and Melan arch methods. In this paper, the construction of the J6shi Bridge and the results of performance tests at each stage of the arch rib construction are described. In addition, the design technique of this method is discussed based on the test results.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
