Abstract

In the last decades, the catastrophic consequences due to progressive collapse of structures lead to the necessity to develop design strategies to mitigate this phenomenon. In the years, several design methods have been proposed by codes and guidelines, such as tie force and alternate load path approaches. The former is an indirect method, based on the assumption that the buildings are tied together to enhance continuity, ductility and develop alternate load paths. The purpose of this paper is the investigation of the main parameters affecting the tie force requirement for frame reinforced concrete structures, such as structural grid spacing and mechanical properties, where a comparison is carried out between standard code prescriptions, analytical formulations and experimental results available in literature and rearranged in a database created by Authors.
