Abstract

When a strong earthquake occurs, buildings are often damaged in varying degrees. The safety assessment of earthquake-damaged buildings is an important part of post-earthquake emergency rescue work. The aim of safety assessment is to quickly and effectively assess the safety of damaged buildings and reduce the loss of life and property of people in disaster areas. In the past, the safety appraisal of earthquake site was carried out according to experts' experience, the appraisal results varied from person to person, and the appraisal efficiency was low. In this paper, the seismic safety and availability standards are established by summing up the rich experience of earthquakes in China, and the relationship between these standards and different damage states is proposed, the damage assessment of reinforced concrete and masonry structures is specified in detail. The damage states of different structural and non-structural components are quantified, and the previous seismic damage pictures are added. Then, according to the severity and quantity of earthquake damage, the safety evaluation rules of the whole building are established, and the earthquake damage of the whole building is evaluated. The results show that the safety evaluation results based on these rules are consistent with the actual situation. Therefore, the proposed method can be used for fast and effective security identification.
