Load Distribution and Several Analytic Methods on the Structures Composed of Beams and Joint-beams


Akihiro YAMASHITA
There are some constructional methods to make underground passage-structures without disturbing surface structures, such as railways and highways. Both URT Constructional Method and Pipe Beam Constructional Method are often to make passage-structures typed through bridge. The passage-structures typed through bridge have two main beams and cross beams connected with each other by interlocking joints along their length. As the joints distribute train load to adjacent cross beams, to get the behavior of the passage-structures typed through bridge is necessary to calculate load distribution by not only the connection between main beams and cross beams but also the joints. This paper deals with trigonometric series method, boundary integral equations method, and finite elements method for analyzing load distribution on joint-beams structures.
