چکیده مقاله
Progressive collapse is a complex process and the quantitative understanding and analysis theory about the phenomena are still not mature. Several buildings have collapsed in this fashion in recent years, and the possibility of progressive collapse is a source of continuing concern. Recently, finite element simulations have been used as an alternative for expensive and time-consuming experimental tests. As most of these research were done in scaled mood, in this study the effect of scale on the results of analysis is considered using ABAQUS software. First, a finite element method is proposed and validated using eight half scale specimens. Then the same sub-assemblages are modeled and analyzed in full scale and the results are compared with scaled specimens. Results showed that the full scale specimens had better strength than scaled specimens. In addition, final displacement in catenary action doubled for full scale specimens compared to the scaled types. The graphical results also showed that the number of bar fraction in full scale specimens was more than scaled specimens.
