摘要

马来西亚半岛受遥远的苏门答腊岛俯冲带地震影响最大。与此同时，马来西亚东部遭受了菲律宾和印度尼西亚的大地震。大部分海上平台位于丁加奴、沙巴和沙捞越。超过65%的海上平台结构超出了20-30年的设计范围。本研究旨在确定现有三足平台在地震荷载作用下的易损性和风险分析，研究海洋平台在大、小地震荷载作用下的行为，研究海洋平台的动力特性。SAP 2000用于分析和建模三足海上平台。在sap2000中，将执行响应谱、时程和自由振动。平台的混合荷载包括恒载、外加荷载、环境荷载和地震荷载。海上平台的位置参照美国石油协会(API)标准。与时间历史相比，海上平台下的主要地震发生在埃尔森特罗，次要地震发生在亚齐。根据本研究，马来西亚可以承受这种低地震活动，整体关节加速度，速度和位移。

Seismic Effect of the Offshore Structure Under Different Earthquake Loadings

Peninsular Malaysia is most affected by the distant Sumatra subduction zone earthquake. Meanwhile, Eastern Malaysia was subjected to major Philippine and Indonesian earthquake. Most of the offshore platform is at Terengganu, Sabah, and Sarawak. More than 65% of the offshore platform structure exceed the range of design between 20-30 years. This research aims to determine the vulnerability and risk analysis for the existing 3-legged offshore platform under earthquake load, study the behaviors of an offshore platform under major or minor earth-quake loading, and study the dynamic characteristic of an offshore platform. SAP 2000 is use to analyses and modelling the 3-legged offshore platform. In SAP 2000, the response spectrum, time history, and free vibration will be performed. The mixed load of the platform consists of dead load, imposed load, environment loads, and earthquake load. The position of the offshore platform has referred to American Petroleum Institute (API) standard. The major earthquake under off-shore platform is El-Centro and the minor is Aceh compared to time history. Based on this study, Malaysia can withstand this low seismic activity, overall joint acceleration, velocity and displacement.

期刊介绍： The International Journal of Integrated Engineering (IJIE) is a single blind peer reviewed journal which publishes 3 times a year since 2009. The journal is dedicated to various issues focusing on 3 different fields which are:- Civil and Environmental Engineering. Original contributions for civil and environmental engineering related practices will be publishing under this category and as the nucleus of the journal contents. The journal publishes a wide range of research and application papers which describe laboratory and numerical investigations or report on full scale projects. Electrical and Electronic Engineering. It stands as a international medium for the publication of original papers concerned with the electrical and electronic engineering. The journal aims to present to the international community important results of work in this field, whether in the form of research, development, application or design. Mechanical, Materials and Manufacturing Engineering. It is a platform for the publication and dissemination of original work which contributes to the understanding of the main disciplines underpinning the mechanical, materials and manufacturing engineering. Original contributions giving insight into engineering practices related to mechanical, materials and manufacturing engineering form the core of the journal contents.
