Dynamic Loading Analysis ofthe Telescopic Jetty Gangway

This report basically discusses the research done and basic understanding of the
chosen topic, which are Dynamic Loading Analysis of the Telescopic Jetty
Gangway. This project is an inclusive research study regarding the hannonic response
on a telescopic jetty gangway structure. The project is related to the study on the
dynamic characteristics of the jetty gangway structure which exerted the hannonic force
at the free end of the beam structure. From the studies, we could find the values of the
hannonic response on the telescopic jetty gangway and the mode shape under the
influence ofhannonic force of sea wave.
The mathematical models are developed based on simplified 1-beam geometry
by using Newtonian method. The mathematical solutions of the jetty gangway were
conducted in two different techniques. In the first technique, the upper and the lower
beam were treated as separated parts. The separated calculation processes are conducted
in both upper and load beam structure. For the second technique, the jetty gangway
structure was treated as a single structure with different value of cross sectional areas at
the begiuning, middle and far end of the jetty gangway.
The mode shapes and the responses of the beam structure from both techniques
were plotted and the data taken were compared with the mode shapes values and
patterns of the single uniform beam taken from the previous references and studies.
