In this research are presented the esperimental measurement and the theoretical studies concernting the fields of the spatial deformation and the stresses of a spatial structure for a petroleum coke plant as consequences of the variations of the vertical seismic loadings. These fields are calculated using the finite element method.
The numerical result obtained from this study are usually used in the regineering practice to optimal design the spatial structure of petroleum coke plant or to predict and verify the affective stress of the structura. These methods permit a detailed study of fields with highly accuracy and for this reason are useful tool in the system designing.

To provide a high coefficient of security in exploitation, the activity of design engineering of a spatial metal structure for a petroleum coke plant must take into consideration the important fields of deformations and stresses resulting as consequence of the seismic loadings.
This research work presents in synthesis the systematic theoretical study through numerical simulation concerning the distributions of the deformations and stresses fields as consequence of the vertical seismic loadings applied to a petroleum coke plant.
The plant subject to study is in exploiting from 1996, in a continuous regime work, on the petro-chemistry platform of oil distillery on the Onesti, Romania. This plant has a production of 385 tones petroleum coke in 48 hours and in the constructive solution presented there is an ensemble with four identical section which work alternatively in cycles by 48 hours.
Seismic analysis of the petroleum coke plant is made with the computer modeling technique that offers the optimum solutions in the seismic design.

|What is you overall assessment of the technical feasibility of the research result?Care este evaluarea generală a fezabilităţii tehnice pentru rezultatul CD?|
|The analysis with the Finite Element Method provides the spatial fieldsof deformations and stresses with high accuracy in optimum time.
The maximal value of the resultant deformation are equel with Urez = 25,35 mm. The rezultant of stress on joint between the cylindrical body and the taper bottom have a maximum value equal with σrez ≤ 76,63 daN/mm2. The maximum effective values of stress are under admissble limit σadm/100000 cycles = 95 daN/mm2 coresponding to values give by STAS 2883/3-88 for alloy steel 16Mo5b which are used to build the plant structure.
The numerical results obtained in this study are commonly used in engineering practice
- to design optimal spatial structure of coking chambers of oil products
- to predict and verify the effective efforts of the structure. This method enables a detailed study on the areas with extremely high precision and therefore is a useful tool in the design system.
Technically, the project can be considered as one with minimum risk.
