Abstract
Design of a bridge that using trusses to transfer the load to the embankment. The
architecture concept is all about a bone of a dinosaur that have mention as the
superstructure. In this context, we are relating the bone of the primate in the dinosaur era
which has the ability to support its own weight. The massive bones of this creature are
unique primarily when we refer to its backbones. The engineering concept that have we
use is arch bridge. The trusses in the middle of the bridge will take the load and transfer it
to the embankment. To make sure that the arch is stable we are using some more trusses to
pull the arch to the piers. By using only steel as our materials, we do not have a lot of
options to do. The arch and the trusses are using double C beams as the materials. Hence,
the beams are using I beams. The problem of our design is the tensile in the trusses that
pull the arch to the piers are high and the beams that are allowable to use are small.
To solve this problem, we choose to make the length between the pier and the arch shorter
than before to reduce the tensile and we use some series of arch below the bridge to make
sure that the bridge can stand. So, by design this bridge we think that it is not an easy work
to do as an engineer. We have to looking for all factors to make sure that our bridge will be
build successfully.
