Seismic response of a typical 3-legged jacket of fixed offshore platform in Malaysia due to Philippines earthquake

The offshore structural design practice in Malaysia only focus more on wind and wave effects analysis rather than seismic effect. At the east of Malaysia, the Philippine plate moves westward with an estimate velocity of 80mm/year and cause micro faults in Sabah. Thus, this thesis develops the earthq...
