Abstract

A high-rise building is associated with the construction of a considerable number of levels and is related to large lateral displacements due to dynamic loads such as earthquakes and wind. In these buildings the Outrigger system allows these displacements to be mitigated, however, finding the best location has been a variant that has been left to the experimentation and experience of the calculator. In this work, it is proposed to find the best location, analyzing the changes of the torsion centers between levels in two three-dimensional reinforced concrete buildings. Two buildings 20 and 30 levels were analyzed, with a slenderness ratio of 0.375 and 0.225, 0.25 and 0.15, respectively; they were placed in two, three and four Outrigger systems varying their location along the height. The best structural behavior was found in the buildings with the greatest slenderness (0.225 and 0.15), that is, buildings with the highest height and the lowest base, and with the least number of Outrigger systems.
