海洋平台生活楼板架结构抗爆性能简化预报方法

Research on simplified forecasting method for anti-knock performance of grillage structure of accommodation on the offshore platform

海洋平台易发生油气泄露引发爆炸事故,进而造成结构损伤、设备损毁以及人员伤亡事故。生活楼是海洋平台上作业人员的生活区及极端环境下的避难场所,其结构在设计过程中应考虑油气爆炸载荷作用下的安全性问题。本文以某海洋平台生活楼板架结构为研究对象,基于单自由度理论研究求解结构等效单自由度系统在油气爆炸载荷下的结构响应解析式,并绘制响应曲线。通过与数值仿真分析进行对比分析,验证了理论分析结果的可靠性。本文研究成果可有效指导海洋平台结构抗爆设计。

Offshore platform is prone to explosions caused by oil and gas leaks,causing structural damage,equipment damage,and casualties.The accommodation of Offshore Platform is a living area for workers and an evacuation site under extreme circumstances.The safety of the structure should be considered during the design process.In this paper,the Grillage Structure on the Accommodation of Offshore Platform is used as the object of Research.The analytical expressions of the Dynamic response of the Grillage Structure on the accommodation under blast are solved based on the method of single degree of freedom and a response curves are drawn.The results are compared with the simulation solution and verified,which proves the dependability of the theoretical analysis results established in this paper.
