Evaluation of Structural Costs in Building - Simulation of the Impact of the Height and Column Arrangement

Modeling is a useful tool for decision making in the project phases. In the case of reinforced concrete structures, we must be able to locate representative parameters in order to optimize costs. This paper assesses the impact of the column arrangement and building height. The variation of the costs for the foundation and two floor interaxis are discussed. The results are assessed by the ratio of cost per square meter executed. The optimization of the geometry of the building is determined by the interaxis distances and the selected structural thickness. In the case studied the arrangement of the pillars in a 6x6 meters grid using 4 heights offers the best economic results.
