합성마찰 진자형 내진장치{An earth quake-proof apparatus of composition friction pendulum type}An earth quake-proof apparatus of composition friction pendulum type

본 발명은 지진으로부터 각종 전력설비, 발전소, 교량 내지는 건축 구조물을 보호하는 내진장치에 관한 것으로, 더욱 상세하게는 지진 발생시 지진과 구조물과의 공진(Resonance)을 피하여 지진력이 구조물에 상대적으로 약하게 전달하여 각종 구조물의 안정성을 확보하고 보호할 수 있는 합성마찰 진자형 내진장치에 관한 것이다.The present invention relates to a seismic device that protects various electric power facilities, power plants, bridges, or building structures from earthquakes, and more particularly, by transmitting earthquake force relatively weakly to the structure by avoiding earthquake and resonance between structures during an earthquake. It relates to a synthetic friction pendulum-type seismic device that can secure and protect the stability of various structures.

주지된 바와 같이 지진의 특성은 단층의 크기나 모양 또는 암석의 파괴형태가 다르고, 전파경로 하부표층 지반에 따라 상당히 영향을 받도록 되어 있으며, 국내 각종 구조물의 내진설계를 위해서는 지반특성이 반영된 설계응답 스펙트럼을 구하여야 하나, 이미 외국에서 개발된 기술을 도입한 실정이었다.As is well known, the characteristics of earthquakes vary in the size and shape of faults, or in the form of rock breakdown, and are significantly affected by the ground surface of the lower propagation path, and the design response spectrum reflects the ground characteristics for seismic design of various structures in Korea. However, it was necessary to obtain the technology, but the technology had already been developed in foreign countries.

종래에도 국내에서 소개된 내진장치를 살펴보면, 주로 교량용 내진 받침으로 납면진 받침대, 고감쇠 고무받침대 또는 탄성마찰 포트 받침대 등이 알려져 있는바, 이러한 종래 내진장치들은 국내 지진의 고유특성이나 건설현장 상황을 반영하기 어려운 실정이면서 지진대비 상용화하기에 고가이고, 신뢰성에서도 확신을 가질 수 없는 문제점 등이 제기되어 왔다.Looking at the seismic devices introduced in Korea in the past, mainly the seismic support for bridges, such as lead-free earthquake support, high attenuation rubber support or elastic friction port support is known, these conventional earthquake resistance devices are unique characteristics of the domestic earthquake or construction site situation Although it is difficult to reflect this situation, it is expensive to commercialize against earthquakes, and problems such as unreliability have been raised.

이에 본 발명은 종래 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 지진 발생시 지진동으로부터 구조물을 격리시키고 안정적으로 구조물의 하중을 지지하면서 지진동 폭을 감소시키어 지진 후 구조물의 원위치화 기능을 수행할 뿐만 아니라, 송변전 설비기초, 발전소, 교량, 건물 및 저장탱크 구조물 등 각종 구조물에 상용화 적용시키면서 제조단가를 낮출 수 있는 합성마찰 진자형 내진장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the problems as described above, to isolate the structure from the earthquake during the earthquake, and to stably support the load of the structure while reducing the width of the earthquake movement to perform the function of repositioning the structure after the earthquake as well as The purpose of the present invention is to provide a synthetic friction pendulum-type seismic device that can lower the manufacturing cost while commercializing and applying to various structures such as power transmission substation facilities, power plants, bridges, buildings, and storage tank structures.

상기와 같은 목적을 달성하기 위한 본 발명은 각종 구조물의 밑면과 기초면 사이에 설치되어 지진 발생시 구조물의 동적거동을 완화시키는 내진장치에 있어서, 상기 구조물의 밑면에 앵커볼트로 고정되는 바닥판과 구조물의 기초면에 고정되는 베이스판 사이에는 지진동 감쇠부가 내장되되, 이 지진동 감쇠부는 상기 바닥판과 일체로 연결된 상부 오목판과, 이 상부 오목판의 오목홈에 접하는 볼록 구형베어링 및, 이 볼록 구형베어링이 안착되는 베이스판에 고정된 안내베어링 시트로 이루어져 있으면서 상기 상부 오목판 둘레에 전단키와 부반력 방지장치가 장착되어 있다.The present invention for achieving the above object is installed between the bottom and the base surface of the various structures in the earthquake-resistant device to mitigate the dynamic behavior of the structure during the earthquake, the bottom plate and the structure fixed to the bottom of the structure anchor bolt Between the base plate is fixed to the base surface of the earthquake motion damping portion is built, the earthquake motion damping portion is the upper concave plate connected integrally with the bottom plate, the convex spherical bearing in contact with the concave groove of the upper concave plate, and the convex spherical bearing is seated It consists of a guide bearing sheet fixed to the base plate is a shear key and a negative reaction prevention device is mounted around the upper concave plate.

상기와 같이 본 발명에 따른 합성마찰 진자형 내진장치는 지진동의 특성을 이용하여 구조물의 고유주기를 지진의 탁월주기(倬越週期 : Predominant Period) 대역과 어긋나게 함으로써 지진과 구조물과의 공진(Resonance)을 피하게 하여 지진 력이 구조물에 상대적으로 약하게 전달되게 하는 개념으로, 미끄러짐에 의한 면진장치의 항복 후에는 마찰면의 곡률반경에 의해 복원력이 작용하고 복원력의 크기 및 이에 대응되는 강성은 마찰면의 곡률반경과 면진장치에 작용하는 수직방향 축하중에 의해 결정되며, 마찰면의 곡률반경을 조성하는 전체 구조물의 고유 진동수를 원하는 값으로 이동시켜, 마찰면의 미끄러짐 발생시 거동을 통하여 에너지를 소산시킬 수 있는 능력을 발휘하고 정지 마찰계수에 근거한 임계하중의 작용 이전에는 미끄러짐이 발생하지 않으므로 바람이나 기타 진동하중에 충분히 저항할 수 있도록 되어 있으며,다음과 같은 효과를 지닌다.Synthetic friction pendulum-type seismic device according to the present invention as described above by shifting the natural period of the structure with the predominant period of the earthquake using the characteristics of the earthquake motion (Resonance) between the earthquake and the structure It is the concept that the seismic force is transmitted relatively weakly to the structure by avoiding the damage.After the surrender of the seismic isolator due to the slip, the restoring force acts by the radius of curvature of the friction surface, and the magnitude of the restoring force and the corresponding stiffness of the friction surface It is determined by the radius of curvature and the vertical axis acting on the seismic isolator, and it is possible to dissipate energy through the behavior of slippage of the friction surface by moving the natural frequency of the entire structure that creates the radius of curvature of the friction surface to the desired value. The slippage does not occur before the action of the critical load based on the static friction coefficient. Therefore, it is able to withstand wind or other vibration load sufficiently, and has the following effects.

- 지진동을 구조물로부터 격리,-Seismic motion is isolated from the structure,

- 지진동으로부터 안정적으로 건물의 하중을 지지,-Supports the load of buildings stably from earthquakes

- 지진동 폭을 작게하고, 지진 후 구조물의 원위치화의 기능을 수행. -The earthquake movement width is reduced, and the function of the original position of the structure after the earthquake is performed.

본 발명의 성능을 사전에 평가하기 위해 지진에 대한 구조물의 해석에 널리 사용되고 있는 Sap 2000프로그램을 사용하였다. 일예로, 변압기 본체는 강체거동(Rigid Motion)을 하는 것으로 가정하였으며 변압기 중량은 345kV의 제원의 179tonf를 사용하였으며 무게중심에 작용하는 것으로 모델링 하였다. 8개소에 25tonf 용량의 본 발명의 내전장치를 배치하였으며, 지진파는 송변전설비 표준응답 스펙트럼에 준하도록 인공 지진파를 생성하였다. 인공 지진파의 응답 및 파형에 대한 사항은 그림 3.12와 같다. 종래 일반 앵커 고정형식은 그림 3.13(a)와 같으며, 본 발명은 그림 3.13(b)와 같이 모델링하였다.In order to evaluate the performance of the present invention in advance, the Sap 2000 program, which is widely used for the analysis of structures against earthquakes, was used. For example, the transformer body is assumed to be rigid motion (Rigid Motion), and the transformer weight is 345kV specification of 179tonf and modeled as acting on the center of gravity. The earthquake resistance device of the present invention having a 25 ton capacity was disposed at eight places, and the seismic waves generated artificial seismic waves in accordance with the standard response spectrum of the transmission and substation facility. The response and waveform of the artificial seismic wave are shown in Figure 3.12. Conventional anchor fixing type is shown in Figure 3.13 (a), the present invention was modeled as shown in Figure 3.13 (b).

지진시각 이력 해석결과, 본 발명은 그림 3.15와 같이 하중-변위곡선을 변압기의 주기를 늘리고 에너지를 감쇠시키고 있다. 기초부 전단력(Base Shear)과 변압기 본체 가속도(Acceleration)에 대한 그림 3.16의 결과를 분석하면 베이스 전단이 일반앵커 고정방식에 대한 61%가 감소하였으며 변압기 본체의 가속도는 62% 감소시켰다. 베이스 전단은 변압기의 안전성에 관련되며 변압기 본체의 가속도는 상부 부싱에 가속도를 전달시키는 역할을 하게 된다.As a result of seismic time history analysis, the present invention increases the period of the transformer and attenuates the energy of the load-displacement curve as shown in Figure 3.15. Analyzing the results in Figure 3.16 for Base Shear and Acceleration of the Transformer Body, base shear reduced 61% for the conventional anchoring method and 62% for the transformer body. The base shear is related to the safety of the transformer and the acceleration of the transformer body serves to transfer the acceleration to the upper bushing.

본 발명의 적용으로 베이스 전단 및 변압기 본체 가속도를 감소시킬 수 있음을 알게 되었으며 마찰계수의 조정으로 추가적인 감소도 가능할 것으로 판단된다.It has been found that the application of the present invention can reduce the base shear and transformer body acceleration, and further reduction may be possible by adjusting the friction coefficient.
