ANALYSIS OF JETTY PLATFORMDUE TO EARTHQUAKE AND STORM WAVE (BATAMSEA, INDONESIA)

Abstract

Structural design of offshore is initiatedwith an evaluation of the structure condition of environmental loads, namely wave and ship impacts. Jetties are designed for the purpose of resistingthese forces, on other hands, they must remain stable under other loads namely earthquake attack. Waves is the most critical loads on offshore structures. Other loading conditions such as storm wave and tsunamialso include to be analyzed paper. In this way, the analysis of jetty structureneed software analysis SAP2000 which support the automatic wave and wind load distribution.Automatic wave load definition using API WSD2000 which automatically load pattern definition for structure load. For wave load using automatic API 4F 2013 provided by SAP2000. Results of the analysis showed that maximumdeformationand capacity ratio for jetty structure condition were 5mmdan 0,5 respectively.
