Developed drift damage index-based failure criterion for framed-wall structure system

Abstract

Recently, significant progress has been observed in high-rise buildings, positively affecting the economy and society. Since the damage and failure of these structures could cause tremendous disasters for society and humanity, investigating the damage performance of the building and assessing this damage is urgently needed. The numerical methods combined with the damage mechanics theory have shown to be a crucial tool to simulate and capture the damage of these structures. Therefore, this study introduces an effective simulation procedure and performs the non-linear dynamic analysis of a framed-wall structure with different heights under various seismic events and intensities using the incremental dynamic analysis technique. The tensile damage is well captured through the adopted damage model, and it is illustrated that the damage initiation and propagation are varied at different seismic events, which significantly affects the structure response. Moreover, an extensive study on the damage assessment has been provided to evaluate the damage degree of the structure using the Park-Ang damage index. The key point of this study is to recognize an efficient criterion to determine the structure’s state under different dynamic loads. Accordingly, a new formula has been proposed to quantify the damage to the framed-wall structures efficiently with low computational efforts, which will be of great importance in the case of assessing the damage for the city-scale model rapidly. This study demonstrated that the proposed formula could accurately assess the damage induced in the framed-wall structures where the results agree with the calculated values through the Park-Ang damage index. Finally, the results of the collapse state have been emphasized through the collapse analysis, which proves the efficiency and reliability of the proposed formula.
