In this bachelor`s thesis static analysis of point supported girderless ceiling board of a thirtheen floor administrative center CBC was elaborated. Based on the given floor plan, column positions, reinforced cores and storey beams, loads were calculated and preliminary design of bearing elements and shape layout were made. Using computational program CAD-FEM STRAP a ceiling structure was modeled and analyzed, considering most unfavorable combinations of vertical load. According to program results reinforcement drawings for top and bottom part of ceiling board were processed. Also, as a part of this work column punching failure was reviewed, shear reinforcement and reinforcement against chain collapse was designed and put in individual drawing. All of the elements were projected to meet ultimate limit state and serviceability.
