Experimental and Numerical Evaluation of Progressive Collapse Behavior in Scaled RC Beam-Column Subassemblage

Publisher: Hindawi Limited

Date: 2016

DOI: 10.1155/2016/3748435

Abstract: An experimental test was carried out on a 3/10 scale subassemblage in order to investigate the progressive collapse behavior of reinforced concrete (RC) structures. Investigation of alternative load paths and resistance mechanisms in scaled subassemblage and differences between the results of full-scale and scaled specimens are the main goals of this research. Main characteristics of specimen response including load-displacement curve, mechanism of formation and development of cracks, and failure mode of the scaled specimen had good agreement with the full-scale specimen. In order to provide a reliable numerical model for progressive collapse analysis of RC beam-column subassemblages, a macromodel was also developed. First, numerical model was validated with experimental tests in the literature. Then, experimental results in this study were compared with validated numerical results. It is shown that the proposed macromodel can provide a precise estimation of collapse behavior of RC subassemblages under the middle column removal scenario. In addition, for further evaluation, using the validated numerical model, parametric study of new subassemblages with different details, geometric and boundary conditions, was also done.

Analytical investigation of reinforced concrete frames under middle column removal scenario

Publisher: SAGE Publications

Date: 08-12-2018

DOI: 10.1177/1369433217746343

Abstract: A simplified theoretical model is developed in the present study in order to predict the general behavior and resistance of reinforced concrete frames under column removal scenarios. The proposed model defines the load–deflection response of the middle joint above the removed column based on a four-stage procedure: classical beam mechanism stage, arching stage, transient stage, and catenary stage. A comprehensive evaluation study using two validation approaches is performed in order to investigate the reliability of the introduced model. For validation of theoretical model, the results of a comprehensive finite element method and experimental data were utilized and the results were compared with the theoretical model. The results demonstrated that the proposed theoretical procedure can establish a reliable foundation for progressive collapse assessment of reinforced concrete frame structures. The proposed model can also predict behavior of symmetrical frames, and this was validated by good agreement between finite element results and the results of the proposed numerical model.
