| Design and Erection of Enim River Bridge, Sumatra, Indonesia Katsuhiro Murata, Hiroichi Matsuo, Akihiro Uemura |

Synopsis : Kawasaki Steel was awarded a contract for the design, fabrication and erection of a 181-m-long steel bridge by the Indonesia State Railways (PJKA). The work began in September 1983 and site erection was completed at Bukit Asam, Sumatra, Indonesia in December 1985. The bridge is a four-span continuous partial composite girder type structure. This type of superstructure was chosen for economy and to provide its deck slab with multipurpose usage for both railway and roadway transportation. Special features incorporated into the design include: (1) Provision of a composite girder section length equivalent to the length of negative moment, (2) evaluation of loading conditions, deflection, etc., taking into account proof loading for a continuous girder and smooth accommodation of the railway and automotive loads. Erection was accomplished at the site using a cantilever launching method. Girders were assembled one by one using a repetitive erector. Erection work was executed quite safely with satisfactory results. |
