Abstract

The structural design of high-rise buildings is a complex procedure whose development is mainly defined by some leading factors, such as the outstanding height and the groundbreaking shapes. From a scientific point of view, these issues need advanced methods of analysis. Analytical formulations, based on some simplifying hypotheses, allow to model the resistant skeleton of the building with a quick procedure and to determine the best solution for the specific load case. Starting from conditions of equilibrium and congruence, an analytical formulation for the analysis of high-rise buildings subjected to horizontal actions is proposed. The method takes into consideration the most common solutions employed to stiffen horizontally a building, such as shear walls, frames and braced frames. A faster data preparation as well as a more transparent method of analysis, but also the capabilities to identify the distribution of the external forces within the stiffeners as well as the trend of the main stresses in each bracing represent the benefit provided by the formulation. Furthermore, for the case of thin-walled open section shear walls, the bimoment action is clearly derived. In order to highlight the effectiveness of the proposed method, an example regarding tall buildings is carried out.
