Seismic Reliability Analysis Of Marine Ecological Simulation Cabin And Earthquake Damage Prediction

In recent years, the research of marine ecological environment has become hot issues, due to the particularity of marine research, marine research or laboratory simulate experiment is difficult to fully reflect the actual circumstances of the sea change for a long time. Therefore, the construction of the controlled Marine ecological environment simulation experiment system, has become the ideal platform to solve the problem of Marine science. At present, many universities and research institutions have large experimental water designed for research purposes of level process, cannot meet the urgent needs of the current research on Marine vertical process. In order to solve this problem, Marine Research Institution of Shandong University putted forward to build the sea simulation system of marine ecology for the purpose of vertical process on land.The Marine Ecological Simulation Cabin (MESE) is vertical thin wall cylindrical shell structure, main features:1) The height and diameter ratio is bigger; 2) Long tube structure; 3) Diameter and the thickness ratio is bigger; 4) internal filled with water. This structure prone to failure under seismic dynamic, and lose bearing capacity, bulkhead deformation or even collapse. This article mainly focus on the seismic reliability analysis of marine ecological simulation cabin and earthquake damage prediction. Specific works as follows:1. According to the characteristics of continental sea vertical depth and marine science experiment requirements, designed the structure of marine ecological simulation cabin, mainly contain light control system, temperature control system, laminar flow control system and sea water physical and chemical parameters of the control and monitoring system.2. According to the specification for design of concrete structures (GB50010-2002), technical specification for the building pile foundation (JGJ94-2008) and the relevant provisions of reference for other similar structure foundation design, designed the foundation of the marine ecological simulation cabin and calculated the seismic performance.3. Using the large finite element analysis software Adina8.5, simulated the earthquake dynamic response of different cabin wall thickness, and then extracted the vertical stress value and the toroid stress, and carried on the variable thickness design of cabin wall.4. Using the large finite element analysis software Adina8.5, simulated the earthquake dynamic response of different earthquake intensity, and then extracted the vertical stress value, the toroid stress value and the wave height of liquid shaking.5. Using the large finite element analysis software Adina8.5, simulated the earthquake dynamic response of different depth of liquid, and then extracted the vertical stress value and the toroid stress value.6. Refer to the technical specification for earthquake disaster prediction and its information management system (GB/T 19428-2003), divided the earthquake disaster grade, and analyzed the influence factors of aseismic reliability of marine ecological simulation cabin, and then summarized the earthquake disaster grade and the macro performance under the different seismic intensity.
