Comparative Evaluation on the Response of New Zealand Buildings to Natural Disasters

With the development of science and technology, research on the response of New Zealand buildings to natural disasters is constantly improving. The exploration of building improvement in New Zealand under natural disasters and the construction and design of natural disaster assessment models based on DRI (Disaster Risk Index) are becoming increasingly important. How to reduce building risks during earthquakes is currently a key issue that urgently needs to be addressed in the entire research on building response to natural disasters in New Zealand. In this paper, based on the relevant research on the earthquake and tsunami in New Zealand, with the help of the absolute disaster level and relative disaster level calculation formula, combined with the simulation experiment, and according to the data results, the following conclusions are drawn: under the natural disasters dominated by earthquakes, New Zealand has improved its buildings in five aspects: building code, construction standards, construction levels, material use, and construction links, and based on the DRI natural disaster assessment model, the comprehensive average reduction in building risk under natural disasters was 15.5%, while the comprehensive average reduction in casualties was 11.5%. This indicates that the natural disaster assessment model based on DRI has a good practical application effect in New Zealand's construction response to natural disasters.
