A GLANCE AT THE CONSTRUCTION OF MANY KINDS OF BRIDGES IN JAPAN

After a general introduction outlining the scale of bridge construction during recent years, the author discusses the materials that have been used. He refers particularly to high tensile steels, weather-proof steels and the increasing use of lightweight aggregates in concrete. Reference is also made to the increasing use of computers to automate the design and drawing of plans of structures and to assist in workshop processes. The advantages conferred by pre-fabrication are discussed and reference made to the attention being paid to the block method of constructing pre-stressed concrete bridges; a number of examples of its use are given. The Author makes particular reference to measures that have been adopted to reduce the noises caused by bridge construction, such as the use of high tensile steel bolts instead of rivets and the increase in the proportion of concrete bridges, which although more prone to problems resulting from earthquakes, are quieter. The remainder of the article gives details of a number of specific bridges which have been constructed recently. These have included girder steel bridges, truss bridges, arch bridges, suspension bridges, cable-stayed bridges and concrete bridges.
