摘要：The project and construction experience of building structures permit to affirm that greatest part of this structures usually are concrete frames with one way slab. This is the reason to develop this systematic study about the influence that concrete and steel used have in this structures. The aim 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 tipical flats over ground, respectively), the concrete class (HI 75, H200, H250, H300, H400 y H500), the steel types (AEH400 and 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 tables and graphs), we made an analysis of materials cost (concrete and steel) and the surface occupied for the columns.
