DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-rise damping structure having an active damping device and a measure for pulling out a pile during an earthquake as part or all of energy for driving the active damping device. TECHNICAL FIELD The present invention relates to an energy conversion type high-rise vibration control structure in which the vibration energy of the vibration of additional concrete poured in as a concrete structure can be used for a structure to be subjected to vibration control.

[0002]

2. Description of the Related Art The behavior of a high-rise structure during an earthquake is based on the behavior of a cantilever supported by the ground, causing a large bending moment on the column base and causing the pile on the pulling side. Pulling is often a problem.

In such a case, a structure has been adopted in which concrete is added to the foundation and the pile is used as a counterweight to suppress the pile, or when the pulling force is large, the pile head and the ground are connected by an earth anchor.

FIG. 3A is a view showing a state in which pulling out of a pile 3 is suppressed by a concrete counterweight 2 on a foundation portion of a high-rise structure 1. FIG. 3B is a diagram illustrating a state in which the head of the pile 3 and the support ground 5 are tightly connected by the earth anchor 4.

[0005] However, the counterweight 2 is merely a weight and does not have a positive restraining force against pulling out. Although the earth anchor 4 is restricted by the binding, the construction is complicated and the cost increases.

The applicant has already disclosed in Japanese Patent Application No. 8-141423 an active vibration damping device in which the vibration energy of an additional building or equipment other than the structure to be damped is installed in the structure to be damped. We propose a highly reliable energy conversion type vibration damping structure that can save energy by using it as the driving energy of the vehicle and can operate even in an emergency such as a power outage.

The present invention is derived from the above-mentioned Japanese Patent Application No. 8-141423, in which a low-cost counterweight is vibrated, the vibration energy is converted into potential energy, and this energy is accumulated to form a high-rise structure. It is used as a drive source of the installed vibration control device, and the effect of vibration control is increased with a little power.
It suppresses the bending moment acting on the foundation and prevents the pile from being pulled out.

According to a first aspect of the present invention, the additional concrete is supported by a seismic isolation device for preventing the foundation of the high-rise structure from being pulled out, and vibration energy generated in the additional concrete is converted into potential energy. An energy conversion type high-rise control structure characterized by comprising a conversion means and a means for storing the potential energy, and driving a vibration damping device provided on the ground floor via the means for storing the potential energy.

A third aspect of the present invention is limited to a case where the lower two floors or the multi-story floor of the high-rise structure has a flexible structure, and the vibration damping device is disposed concentrated on the upper floor of the lower floor. .

According to a fourth aspect of the present invention, an energy conversion device for placing additional concrete, a seismic isolation device, and an energy storage device are limited. The energy conversion device includes a structure to be subjected to vibration damping and a laminated rubber. A hydraulic cylinder for connecting the supported upholstered concrete, wherein the energy storage device is an accumulator interposed between the hydraulic cylinder and a fuel supply port of a vibration control device installed in a structure to be controlled. The main purpose is the energy conversion type high-rise vibration control structure.

Next, the operation will be described.

The counterweight is mounted on a seismic isolation device such as a laminated rubber to increase the displacement of the town weight so that a large vibration energy can be obtained.

According to the present invention, for example, a hydraulic cylinder is disposed between the foundation of the building and the counterweight, and the vibration energy of the counterweight is converted into the potential energy called hydraulic pressure, and the potential energy as hydraulic pressure is stored in the accumulator, for example. I do. By connecting the accumulator and the vibration control device on each floor above ground, for example, an actuator,
The potential energy stored in the accumulator is used as a drive source of the actuator to control the high-rise structure while suppressing the bending moment of the column base, thereby exhibiting the effect of preventing the initial pull-out.

According to a second aspect, the horizontal stiffness of the lower floor of the high-rise structure is made flexible, and the natural period of the building is made longer,
By keeping the energy required for damping small and concentrating the damping structure in one place, the energy storage device,
For example, the supply of energy from the accumulator is facilitated.

According to the third aspect of the present invention, if a damping device is provided on the column-to-column frame of a two-layer structure with a single layer, the damping constant is further increased, and the horizontal rigidity of the lower story is easily made flexible and the damping effect is enhanced. It focuses on that.

According to a fourth aspect of the present invention, the energy conversion device is a hydraulic cylinder interposed between the foundation and the counterweight, and the energy storage device is the hydraulic cylinder, The main purpose is to limit the accumulator to be interposed between the fuel supply ports of the vibration control device installed on the structure to be controlled.

[0026]

According to the present invention, active control can be performed during an earthquake by using a counterweight, which was conventionally only used as a weight, as an energy generating device, and the vibration of a structure can be reduced. Furthermore, in the general structure, even when the pull-out force is large and an earth anchor must be used, by mounting the present invention, the swing of the structure is reduced, the pull-out force is reduced, and without using the ground anchor,
Since the pulling force can be treated, it leads to cost reduction.
