Nemetschek Engineering User Contest 2009 • Category 2: CAE Housing & Buildings 97 2 Office building, Bucharest Our designing team did a remarkably work in a very short time only because of the program’s reliability and accuracy. That is why we purchased the SCIA program in the first place. The program computed dynamic and seismic analysis in a very short period of time, in comparison with others design and analysis program (e.g. ETABS). Because our operating system was Windows Vista x64 we encountered some difficulties in running Scia for that type of O.S., but due to fast response from the Nemetschek Group of Romania we quickly resolved that problem. Another problem was the height of the reinforced concrete frame beams, which, because of the big distance between the columns, was too big. The solution for this problem was to increase the storey height, but for that, we needed to reduce the number of storeys. Then another problem appeared: the reinforced concrete columns were not able to resist the new enlarged beam forces. Therefore we increased the dimensions of the columns up to 1.00 by 1.00 m. Also, for the columns to be able to take the shear forces transmitted by beams, we placed a composed HEB steel profile inside the columns. That type of composite section reduced a lot the displacements and, in addition, increased the stiffness of the structure. In order to keep the reinforced concrete slab with a small depth, capable to take the designed pressure, and in addition to be able to transmit horizontal forces to columns, we created a deck, which is supported by steel beams network. Those steel beams will be supported by the reinforced concrete beams of the frames. The rest of the project, with the solution for the type of structure accepted, will be detailed for execution. We are confident that the detailing process will also be dealt with in a satisfactory way with Allplan.
