Overall Stability Analysis of Dome Steel Structure on Dome Roof in Large Tanks Based on FEM
In petrochemical industry, single layer dome steel structure is usually used to support dome roof in cylindrical tank. This paper takes a dome steel structure with a diameter of 52m(type Kiewitt)designed by a petrochemical corporation of Lianyungang as an example. According to the People's Republic of China industry standard JGJ61-2003, utilizing Arc-Length method of the finite element analysis software Abaqus to analyze this example’s overall non-linear geometry, and utilizing finite element increment iteration to analyze this example’s response during the whole loading, we obtain the instability critical loads eventually. The results reveal that under given loading the load factor of dome steel structure is 5.426 and overall instability will not occur.
