Description
技术领域technical field
本发明属于建筑结构隔震减震控制领域，特别是涉及一种多功能减震支座。The invention belongs to the field of shock-absorbing control of building structures, and in particular relates to a multifunctional shock-absorbing support.
背景技术Background technique
支座隔震属于被动控制技术，是通过在上部结构和下部支撑体系之间设置隔震装置来减少上部结构的地震响应。世界上每年发生破坏性地震近千次，一次大地震可引起上千亿美元的经济损失，导致几十万人死亡或严重伤残。我国地处世界上两个最活跃的地震带上，是遭受地震灾害最严重的国家之一，地震造成的人员伤亡居世界首位，经济损失也十分巨大。地震中建筑物的大量破坏与倒塌，是造成地震灾害的直接原因。地震发生时，地面振动引起结构的地震反应。对于基础固接于地面的建筑结构物，其反应沿着高度从下到上逐层放大。由于结构物某部位的地震反应 ( 加速度、速度或位移 ) 过大，使主体承重结构严重破坏甚至倒塌；或虽然主体结构未破坏，但建筑饰面、装修或其它非结构配件等毁坏而导致严重损失；或室内昂贵仪器、设备破坏导致严重的损失或次生灾害。为了避免上述灾害的发生，人们必须对结构体系的地震反应进行控制，并消除结构体系的“放大器”作用，结构消能减振技术是把结构的某些非承重构件( 如剪力墙、连接件等) 设计成消能杆件，或在结构的某些部位 ( 层间空间、节点、连接缝等 ) 安装隔震装置。在小风或小震时，这些隔震装置具有足够的侧向刚度以满足使用要求，结构处于弹性状态；当出现大震或大风时，随着结构侧向变形的增大，隔震装置率先开始工作，产生较大阻尼，大量消耗输入结构的地震或风振能量，使结构的动能或弹性势能等能量转化成热能等形式耗散掉，迅速衰减结构的地震或风振反应 ( 位移、速度、加速度等 )，使主体结构避免出现明显的非弹性状态，保护主体结构及构件在强震或大风中免遭破坏。因为地震等原因传输给建筑结构的外部能量，是结构产生振动的根源，所以在结构中设置隔震装置，增加耗能量，将会减少结构的振动反应。目前研究开发的隔震装置容易被压碎而失去作用，致使其耗能能力大幅降低。因此，一些隔震装置的制造工艺和耗能性能等仍需要进一步改进。Bearing isolation is a passive control technology, which reduces the seismic response of the upper structure by setting an isolation device between the upper structure and the lower support system. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is seriously damaged or even collapsed; loss; or damage to indoor expensive instruments and equipment leading to serious losses or secondary disasters. In order to avoid the occurrence of the above-mentioned disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system. Components, etc.) designed as energy-dissipating members, or in some parts of the structure (interstory space, nodes, joints, etc.) to install shock-isolation devices. When there is a small wind or a small earthquake, these isolation devices have sufficient lateral stiffness to meet the requirements of use, and the structure is in an elastic state; when there is a large earthquake or strong wind, as the lateral deformation of the structure increases, the isolation device takes the lead Start to work, produce greater damping, consume a large amount of earthquake or wind vibration energy input into the structure, convert the kinetic energy or elastic potential energy of the structure into thermal energy and dissipate it, and quickly attenuate the earthquake or wind vibration response (displacement, velocity) of the structure , acceleration, etc.), so that the main structure avoids obvious inelastic state, and protects the main structure and components from damage in strong earthquakes or strong winds. Because the external energy transmitted to the building structure due to earthquakes and other reasons is the root cause of the vibration of the structure, so installing a seismic isolation device in the structure and increasing energy consumption will reduce the vibration response of the structure. The seismic isolation devices currently researched and developed are easily crushed and lose their function, resulting in a significant reduction in their energy consumption. Therefore, the manufacturing process and energy dissipation performance of some seismic isolation devices still need to be further improved.
