Nemetschek Engineering User Contest 2009 • Category 2: CAE Housing & Buildings 89 2 Tatra City Multifunctional Complex critical point not only from the calculation point of view but also from the realisation of the construction itself. It was checked in detail by the supplier and the planner. The remaining floors are characterised as a wall system of 200 mm thickness and a plank system of 250 mm thickness. The full solidity of the planks is secured by a circuit firm attic gable. The construction of the elevator wells was designed as a separately standing object, horizontally secured in the particular levels of the planks. The material used in the wall and plank construction was concrete C25/30. The columns were designed from concrete C30/37. Calculation The construction was modelled with the ESA-Prima Win Nexis 60 programme. The whole bearing construction of the object was simulated with the 3D model; this was necessary for the analysis of the construction according to the interesting shape. The basement was solved with the soilin module following the Winkler combination together with the elastic support in the place of the future piles. The sufficient horizontal stiffness was showed so the modelling of the partial ceiling planks could follow. Each ceiling plank got its partial 3D model of its own floor. The most critical ceiling plank construction was the one on the level of the angle bracket above the 9th floor. Here we had to solve some models together with the particular phases of the realisation of the object. The results were the required dimension stiffening drawings directly from the program.
