Abstract:
The project and construction experience of building structures, and a little (but reliable) statistic study, permit to agirm 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 sistematic study about the influence that the height of building, the distance between column and the slab depth have in this structures. The final object is to give some criteria to geometric structure difinition and the materials choice. We have calculated 80 structure buildings modifying the height (small, intermediate and tall, with 5, 12 and 20 tipical floors 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 figures and graphs), we made an analysis to each height of buildings, distance between columns and slab depth choice
