Description

The present invention relates to a method for managing a building foundation having a plurality of support mechanisms arranged on the foundation and supporting the building, and a method for managing the building foundation group.

The foundation of the building is installed on the ground to support the building.
The building consists of multiple columns, multiple beams and slabs.
For example, a building foundation consists of a concrete layer, multiple foundation piles and a foundation structure.
Foundation piles penetrate the concrete layer and are driven into the ground.
The foundation structure is composed of a plurality of foundation members and a plurality of beam members.
When viewed from above, a plurality of foundation members are arranged so as to be scattered in a grid pattern.
Beam members connect the foundation members.
The support mechanism is fixed to the pile head of the foundation pile.
When an earthquake occurs, the foundation pile supports the horizontal force due to the acceleration applied to the building through the support mechanism.
For example, when an earthquake occurs, the horizontal force due to the acceleration of the foundation pile acting on the building is supported via a support mechanism with a seismic isolation function.

It has become clear that recent earthquakes can cause horizontal displacements that were not planned at the time of design.
With large horizontal displacements, the horizontal forces cause excessive bending moments and shear forces on the foundation pile, which can cause unexpected damage to the foundation pile or support mechanism.
On the other hand, when a large overturning moment acts on the building, locking of a part of the support structure of the support mechanism may occur, and the foundation pile or the support mechanism may be unexpectedly damaged.

For example, the support mechanism is a support mechanism with a seismic isolation function that generates spring force and damping force in response to the relative displacement between the building and the foundation.
For example, the support mechanism is a support mechanism with a seismic isolation function that generates the smallest possible damping force in response to the relative displacement between the building and the foundation.
When an earthquake occurs, the support mechanism with seismic isolation function allows the relative displacement between the building and the foundation at the place where the support mechanism is installed so that an excessive load does not act on the horizontal building.
However, if an earthquake of a larger scale than expected occurs, unexpected damage may occur to the foundation piles, the support mechanism with seismic isolation function, and the building.

The conventional management method of the building foundation is as follows.
A specialist will measure the initial value of the support mechanism when the building foundation is completed, then perform regular inspections for 5 to 10 years, and perform emergency inspections when a large earthquake occurs. The measurement items are environmental information such as temperature and humidity, the amount of change in horizontal displacement and vertical displacement, visual inspection, and others. Generally, horizontal displacement and vertical displacement are measured with a micrometer or scale.
The Seismic Isolation Structure Association publishes "Maintenance Standards for Seismic Isolation Buildings".
In addition, the scribe type is generally known as a device for simply monitoring the movement of the entire building during an earthquake.

As mentioned above, in maintenance, periodic inspections or emergency inspections are common at the time of completion. The inspection will be conducted after contacting the contractor or the owner (building owner). Even if there is something wrong with the building foundation, it will have to be post-processed, and the identification of the cause of the trouble will be delayed.
Problems can be avoided if the owner can be notified in real time or on a daily basis, such as warnings, if an abnormality has occurred or is likely to occur by monitoring the support mechanism or seismic isolation layer.

The National Research Institute for Earth Science and Disaster Prevention operates Japan's seismic observation system.
The strong motion observation networks K-NET and KiK-NET, which are seismic observation systems in Japan, provide information obtained from acceleration sensors installed all over the country. Acceleration is installed on the ground surface and is not information inside the building.
