Abstarct: Wharfs are known as one of the most important Key Structures in terms of economical, industrial, political, and military points of view around the world. This matter makes the marine structure very important and very influential for our world. Among the marine structures, wharfs are very important in terms of many aspects such as, getting access to the sea from the earth, landing and bracing the free floated. Open typed wharfs are commonly used around the world because of the variety of their options. Taking to consideration, that our beloved country is in a very high risks of having earthquake specially on Northern and Southern regions, and also, consider the amount of damages that marine structures and wharfs had during the recent earthquakes, developing a perfect design for those structures are essential more than before. In this study, comparisons of different seismic analysis over open typed wharfs were taken into consideration. To achieve that goal, first, the twelve different open typed wharfs have been modeled in SAP2000 and three different analyses were done such as, Static analysis and Spectral analysis; and, at the end the results were compared and studied all together.
