Influencia económica del uso de estudios de mecánica de suelos en el diseño estructural de edificaciones de categoría unidad de construcción baja

Abstract

The analysis of this article emphasizes the importance of considering the study of soil mechanics as an integral part of the process of designing and building two-story houses. In doing so, structural safety is guaranteed and economic resources are also optimized, the main objective is to determine the economic influence of the use of soil mechanics studies. The information provided by these allows evaluating the behavior of the soil and its response to seismic forces, which directly influences the design of foundations and structures of buildings. For the data, three soil mechanics studies and an assumed soil datum (qa, ks and seismic profile of the soil) were observed. Therefore, through the architectural geometry of the structure, we proceeded to design previously based on factored loads, in order to obtain the dimensions of the structural elements. The ETABS computer software was used to model the structure and thus obtain the nominal shear and axial moments in the elements, with which the reinforcing steel and transversal steel were drawn up for the confinement of the elements such as beams and columns. The structural dimensions in footings of the four designs are compared and an oversizing is extended through the analysis of work volumes. The budget was made extremely in the items of the Chamber of the Construction Industry (CAMICON), with which the percentage of the variation in costs for the four buildings (gray work) is obtained as a result and to evaluate the economic influence for future projects of low building unit category structures.
