Description

The present invention relates to a building earthquake damage degree estimation device, a method of using the building earthquake damage degree estimation device, a building earthquake damage degree estimation method, and a program.

2. Description of the Related Art Conventionally, there has been known a seismic motion estimation method for estimating the magnitude of seismic motion at a point where no seismometer is installed when an earthquake occurs (see, for example, Patent Document 1). In the technique described in Patent Literature 1, the magnitude of ground surface seismic motion is observed by a seismometer. In the technique described in Patent Document 1, seismic waves propagating through the engineering bedrock existing below the ground surface are amplified in the surface stratum between the ground surface and the engineering bedrock, and the seismic motion is: It is considered to be observed on the ground surface.
In addition, in the technology described in Patent Document 1, the magnitude of the seismic motion observed on the ground surface is divided by the seismic motion amplification factor of the surface stratum, and the seismic motion at the position on the engineering bedrock corresponding to the installation point of the seismometer converted to the size of In the technology described in Patent Document 1, the magnitude of the seismic motion in the reference area around the position on the engineering bedrock surface corresponding to the installation point of the seismometer corresponds to the engineering bedrock surface corresponding to the installation point of the seismometer. It is estimated based on the magnitude of seismic motion at the upper position. For example, if the size of the reference area is smaller than the distance to the epicenter of the earthquake, the magnitude of the seismic motion is considered to be the same within the reference area. In other words, when the position on the engineering bedrock corresponding to the estimated point on the ground surface exists within the reference area, the magnitude of the seismic motion at that position is the engineering bedrock corresponding to the installation point of the seismometer. It is estimated to be the same as the magnitude of seismic ground motion at the position on the plane.
Furthermore, in the technique described in Patent Literature 1, a seismic motion amplification factor of the surface stratum is multiplied in order to estimate the magnitude of the seismic motion at the estimated point on the ground surface. Since the seismic ground motion amplification factor of the surface stratum changes according to the composition of the surface stratum and the depth of the surface stratum, the technology described in Patent Document 1, for example, measures the gravity anomaly and measures the distance from the ground surface to the engineering basement surface. By estimating the depth and investigating the depth and composition of the surface stratum by boring, the seismic ground motion amplification factor of the surface stratum can be obtained.
By the way, with the technique described in Patent Document 1, although it is possible to estimate the magnitude of seismic motion at a point where no seismometer is installed, it is not possible to estimate the degree of damage to a building constructed at that point. . In addition, the technique described in Patent Document 1 complicates the entire system, resulting in a huge amount of data to be handled.
