建筑橡胶隔震支座/隔震橡胶支座的构造及其抗震原理
建筑隔震技术就是在建筑物的基础或下部结构和上部结构之间设置隔震装置（由隔震器、阻尼装置等组成），形成隔震层，隔离地震能量向上部结构传递，减少输入到上部结构的地震能量，同时延长上部结构的自振周期，降低上部结构的地震反应，达到预期的抗震防震要求，使建筑物的安全得到更可靠的保证。
建筑橡胶隔震支座/隔震橡胶支座的主要构成是橡胶、钢板（和铅芯），通常叠层放置。
叠层的钢板：是隔震支座的“骨架”
叠层的橡胶：是隔震支座的“肌肉”
外层包围的橡胶：是隔震支座的“皮肤”
铅芯：是隔震支座的“韧带”

今天，质量优良的震安隔震系统，不但能保护建筑的结构主体，更能保护建筑内部的人的生命和财产。
真正能做到，小震不知道，大震晚知道。
Seismic base isolation, also known as base isolation,or base isolation system,is one of the most popular means of protecting a structure against earthquake forces.It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus protecting a building or non-building structure's integrity.
Base isolation is one of the most powerful tools of earthquake engineering pertaining to the passive structural vibration control technologies. The isolation can be obtained by the use of various techniques like rubber bearings, friction bearings, ball bearings, spring systems and other means. It is meant to enable a building or non-building structure to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications.
Rubber bearings（LRB/LNR/HDR...） are the most commonly used isolation devices.
Base isolator bearings were pioneered in New Zealand by Dr Bill Robinson during the 1970s.The bearing, which consists of layers of rubber and steel with a lead core, was invented by Dr Robinson in 1974.The earliest uses of base isolation systems date back all the way to 550 B.C. in the construction of the Tomb of Cyrus the Great in Pasargadae, Iran.More than 90% of Iran’s territory, including this historic site, is located in the Alpine-Himalaya belt, which is one of the Earth’s most active seismic zones. Historians discovered that this structure, predominantly composed of limestone, was designed to have two foundations. The first and lower foundation, composed of stones that were bonded together with a lime plaster and sand mortar, known as Saroj mortar, was designed to move in the case of an earthquake. The top foundation layer, which formed a large plate that was in no way attached to the structure’s base, was composed of polished stones. The reason this second foundation was not tied down to the base was that in the case of an earthquake, this plate-like layer would be able to slide freely over the structure’s first foundation. As historians discovered thousands of years later, this system worked exactly as its designers had predicted, and as a result, the Tomb of Cyrus the Great still stands today. The development of the idea of base isolation can be divided into two eras. In ancient times the isolation was performed through the construction of multilayered cut stones (or by laying sand or gravel under the foundation) while in recent history, beside layers of gravel or sand as an isolation interface wooden logs between the ground and the foundation are used.
Today, a good quality isolation system can not only protect the main structure of buildings but also protect people's lives and property inside.（SAFETYINSIDE）
