Abstract

The invention provides a meticulous evaluation method for building earthquake economic loss at a component level, and belongs to the technical field of earthquake engineering. At first, that componentearthquake damage evaluation module is constructed, The seismic damage of each component is evaluated according to the building information model and the vulnerability database by the component seismic damage evaluation module, and then the damage evaluation module is constructed to calculate the seismic economic loss of each component and the building as a whole according to the building information model, the vulnerability database and the repair standard database by the damage evaluation module. Finally, a visualization module is constructed to visualize the damage and loss of buildings. The invention can accurately evaluate the loss to the component, and provides the specific component loss distribution, which provides an important reference for building earthquake repair strategy ordisaster prevention design.

Description

Technical field [0001] The invention relates to the technical field of earthquake engineering, in particular to a component-level method for refined evaluation of building earthquake economic losses. 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 because of the high cost of post-earthquake repairs. For example, on February 22, 2011, a magnitude 6.2 earthquake occurred in New Zealand. After the earthquake, 70% of the buildings had no repair value and were forced to demolish. Therefore, a refined building earthquake loss assessment is very important to the restoration strategy after the earthquake. [0003] At present, the main method of building seismic economic loss evaluation is based on the vulnerability database (Wu Jiwei, Liang Xingwen, Zhu Hanbo. FEMA P-58 new generation building seismic per...
