Analysis of a 4-legged fixed offshore structure in Malaysia under seismic loading

Most structures in Malaysia do not consider for seismic design during its service lifetime. However, structures in Malaysia might be affected by the tremors of earthquake from neighbouring countries such as Philippines, Indonesia etc. The aim of this study is to identify the necessity of implementat...
