The project and construction experience of building estructures, and a little (but reliable) statistic study, permit to affirm that near of 60% constructed buildings are block of tenements. Its structure usually is a concrete frame whith a one-way slab. This is the reason to develope this systematic study about the influence that the concrete and the steel used have in this structures. The final object is to give some criteria to geometric structure definition and the materials choice. We have calculated 80 structure buildings modified the height (small, intermediate and tall, with 5, 12 and 20 typical flats over ground, respectively), the concrete class (H175, H200, H250, H300, H400 y H500), the steel types (AEH400 y AEH500), the distance between columns (short and long, 5.00 and 6.00 m, respectively) and the slab depth (24, 26 and 29 cm). When the calculation results were obtained (as shown on a set of figures and graphs), we made an analysis of materials ratio in columns and beams. The study is made to nine groups of buildings.
