Along with the need to design more slender structures, there is the development of global stability study, which is an important examination to perform a structural design. A lot of software has been developed to assist the designer in his analysis, making the service less laborious. However, it does not mean that nowadays difficulties related to this kind of study are not found. It should be borne in mind that the software will just calculate what is required, then, it is necessary a broad understanding about the subject and the used software for the analysis be done correctly. Through these considerations, this study aims to analyze the global stability of the case study model by “gamma-z” instability parameter, with the help of SAP2000 software. Even by this method, was held second-order analysis in some pillars, and thus, it was showed the influence of nonlinear analysis and global stability in the pillar, because reinforced concrete structures are the elements that suffers most from the second-order effects. With the completion of these analyzes it may be concluded that the height of the pillar and its moment of inertia, are important for the overall stability of the structure, it is they who will set more or less stiffness to the building depending on their size and slenderness, as a result, it must have greater attention to these elements when it comes from a study of the overall stability of buildings. |
