Abstract

The invention provides a component-level refined evaluation method for building earthquake economic loss, which belongs to the technical field of earthquake engineering. In this method, the component seismic damage assessment module is constructed firstly, and the seismic damage of each component is assessed through the component seismic damage assessment module according to the building information model and the vulnerability database. The earthquake economic loss of each component and the building as a whole is calculated by using the permanent database and the repair standard library; finally, a visualization module is constructed, and the three-dimensional visual display of the building earthquake damage and loss is carried out through the visualization module. The invention can make the loss assessment accurate to components, and provide specific component loss distribution, which provides an important reference for building earthquake repair strategy or disaster prevention design.

Description

technical field [0001] The invention relates to the technical field of earthquake engineering, in particular to a refined evaluation method for structural earthquake economic loss at the component level. Background technique [0002] After years of development in building anti-seismic technology, the ability of buildings to resist earthquake collapse has been significantly improved, but many buildings are often forced to be demolished due to the high cost of post-earthquake repairs. For example, on February 22, 2011, an earthquake with a magnitude of 6.2 occurred in New Zealand. After the earthquake, 70% of the buildings had no repair value and had to be demolished. Therefore, refined building earthquake loss assessment is very important for building repair strategies after earthquakes. [0003] At present, the main method of building earthquake economic loss assessment is vulnerability database (Wu Jiwei, Liang Xingwen, Zhu Hanbo. FEMA P-58 New Generation Building Seismic ...
