Scenarios for checking the progressive collapse of reinforced concrete dual system for buildings

Abstract

The objective of the study is a building structure, made of reinforced concrete in a dual system. The structure is a theoretical one but the dimensioning and the considered loads complies the technical regulations in force in Romania. Buildings’ design to resist local damages without collapsing represents a relatively new concern among engineers. Some countries have technical regulations which include sets of rules regarding the design in order to prevent the progressive collapse phenomena. In Romania there are no such rules or specific recommendations. The goal of the study is checking the structure for progressive collapse on the basis of some scenarios proposed by the authors. For both studies the analysis remains in the linear elastic field. The FEM program used was SAP2000-V12.
