“…Traditional ground engineering projects are usually based on a single, robust design and there is often no intention of varying the design during the construction phase [17]. Optional monitoring, if carried out, plays a very passive role to check only if the original predictions are still valid and provide confidence to all parties involved in the process (eg.…”

“…The FEM computational analysis was performed during the design process to prove the fulfillment of a load capacity condition in final state, construction stages and to check the critical details of the superstructure. The experience gained in the course if analysis, similarly to the cases presented in [2][3][4][5][6][7][8], indicates the importance of the method to computationally simulate the structural behaviour. A key problem is the selection of an appropriate theoretical description due to an analysed issue in order to yield correct conclusions.…”
This article presents the execution method of a cable stayed bridge over the Vistula River in Krakow together with FEM-based computational simulations carried out during the design process. The performed calculations concern the global system in its final stage and in the construction stages as well as local analysis of construction details. The obtained results made it possible to work out efficient solutions that contribute to a significant reduction of the project cost and execution time shortening.
“…Structural responses in different loading conditions of ships, floating structures and rig equipment have been studied in [7][8][9][10]. Structures that enable effective operation and exploitation of docks, shipyards and terminals, such as retaining walls, bridges and tanks, have also been analysed in the field of their response predicted by means of the finite element method (FEM) or methods resulting from sensor measurements [11][12][13][14].…”

In this paper, the dome of a tank in the Świnoujście LNG terminal is analysed. Some of the rafter ribs at the connection with hangers were not mounted during construction of the tank dome. Therefore, it has become necessary to estimate its response, which has been done with the aid of some computational models of the dome, that have been created in the finite element method environment. Different local models are studied, aiming to recreate possible outermost conditions of the tank dome response, i.e. with or without composite action between steel and concrete parts of the tank dome. Static calculations with material and geometric nonlinearities are carried out on the computational models, enabling the creation of a load capacity envelope of the rafter with or without ribs. The obtained results are then used to decide if repair works need to be done and whether the missing ribs should be welded.
