Embodiment

[0035] Example: such as Figure 1-3 As shown, the post-earthquake loss distribution calculation method of urban buildings based on the monitoring Internet of Things provided by the present invention comprises the following steps:

[0036]S1. Before the earthquake, collect the information of each individual building in the target city, and establish the data information database of the target urban building group; according to the information of each individual building, establish a simplified multi-degree-of-freedom mechanical model (Multi- degree-of-freedom, MDOF), the numerical models of all individual buildings are established and summarized to form a numerical model of urban building groups.

[0037] Individual building information mainly includes the construction period, building height, number of floors, structural system type, floor area, and standard floor area of ​​each individual building.

[0038] S2. Incorporate the monitoring system of public buildings in the tar...

Abstract

The invention discloses an urban building group post-earthquake loss distribution calculation method based on a monitoring internet of things, and belongs to the technical field of earthquake engineering. Comprising the following steps: collecting single building information in a target city before an earthquake occurs, establishing a data information base of a city building group, and constructing a city building group numerical simulation model; a monitoring system of public buildings in a target city is incorporated into the Internet of Things, and the target city monitoring Internet of Things is built; after an earthquake occurs, earthquake loss calculation simulation is carried out on the urban building group according to actually measured earthquake waves; estimating the earthquake damage degree of the monitored building according to the building internal equipment and home decoration damage condition identified by the monitoring image; and estimating a corrected numerical simulation result based on the damage degree inferred by the monitoring image, and evaluating the damage state of other unmonitored buildings to obtain the post-earthquake loss distribution of the urban building group. According to the method, the earthquake damage distribution of the urban building group can be quickly estimated after an earthquake occurs, and important reference is provided for post-disaster rescue and emergency management.

Description

technical field [0001] The invention relates to a method for calculating post-earthquake loss distribution of urban building groups, in particular to a method for calculating post-earthquake loss distribution of urban building groups based on the monitoring Internet of Things, and belongs to the technical field of earthquake engineering. Background technique [0002] Buildings are the main carrier of various urban activities. Ensuring the earthquake resistance and disaster prevention capabilities of urban buildings is one of the important research topics in the field of earthquake engineering, and it is also the basic work for building "resilient urban and rural areas". Rapid assessment of the damage distribution of urban buildings after an earthquake can provide an important reference for post-disaster rescue and emergency management. [0003] For the simulation of spatial damage and economic loss of urban building groups, the main method currently used is to establish a nu...
