Research on Optimization Method of Post-earthquake Repair Path for Urban Complex based on Functional Demand Orientation

The internal functions of the urban complex are various,and the failure of the complex structure under strong earthquakes will affect the normal operation of the urban regional function. The post-earthquake repair of buildings expects important functions inside the urban complex to be quickly restored and put into use. Reasonable planning of post-earthquake repair paths for the urban complex is the key to meeting the functional demands of such structures. In the existing research,most of the buildings adopted the post-earthquake repair path from bottom to top,without considering the postearthquake functional demands. Based on this,a post-earthquake repair path optimization method for urban complex based on functional demand orientation is proposed. Considering the multi-functional characteristics of the urban complex and the functional correlation between components in different functional areas,a functional loss analysis model based on a fault tree is established,and based on this model,the functional repair
