Stresses, deformations and strains were computed using the finite element modelling for a range of different seismic loading. Numerical modelling based on the finite element analysis was used to represent the system dynamic behaviour. Extensive experimental results, including a detailed study on model performance leads us to conclude that the proposed method can be highly accurate and a useful tool in the system designing.

For this kind of structure, some simplified theoretical methods were usually used previously [1]. But these cannot satisfy the requirements of engineering design. Some 3D models in order to optimise the dynamic behaviour of mechanical structures under various seismic loadings have been developed [1]. This paper introduces a method suitable for engineering mechanical analysis and gives practical solutions in the seismic design of a petroleum coke plant. The petroleum coke plants based on the method of tardy carbon-producing have a continuous work regime [2], [3], [4], [5]. In case of a seismic stress this loading is superposition over the other loads of mechanical nature and thermical cycles determinate by the technological process of work. The total loads may generate significant effects on the strength and the stability of the petroleum coke plant. In this paper is made a study of the states of stress and deformations of a petroleum coke installation with a production m C = 385 tones / 48 hours, found in exploitation on the petrochemistry platform of the oil distillery Onesti from Romania [6], [7], [8].
