Description
技术领域 technical field
本实用新型是一种用于工程结构多维隔减震的支座,属于土木工程结构抗震荷载控制装置的技术领域。The utility model relates to a support for multi-dimensional isolation and shock absorption of engineering structures, which belongs to the technical field of anti-seismic load control devices for civil engineering structures.
背景技术 Background technique
地震作用是土木工程结构所承受的主要控制荷载,也是导致结构发生破坏和倒塌的主要因素。准确地认识结构在地震作用下的响应并采取可靠的保护措施,不仅关系到结构自身的抗震性能,而且直接关系到人民生命和国家经济财产的安全,具有巨大的社会经济效益。Earthquake action is the main control load borne by civil engineering structures, and it is also the main factor leading to the damage and collapse of structures. Accurately understanding the response of structures under earthquake action and taking reliable protection measures is not only related to the seismic performance of the structure itself, but also directly related to the safety of people's lives and national economic property, which has huge social and economic benefits.
隔震是国内外研究和应用最早的被动控制方式,并且大量的试验研究、实际工程建设以及多次的强震考验证明了隔震能够极大地减小土木工程结构地震响应。一般隔震系统必须具备以下特性:承载特性、隔震特性、复位特性、阻尼消能特性以及稳定性和耐久性。形状记忆合金(Shape Memory Alloy,SMA)是一种重要的智能材料,具有抗疲劳性好、阻尼能力强、可恢复变形大及性能稳定等优点。目前,采用SMA对结构隔震的思想主要是将形状记忆合金材料与常规隔震装置复合在一起:①利用形状记忆合金的高阻尼特性来提高隔震支座的耗能能力;②利用形状记忆合金的形状记忆效应或超弹性效应使得支座在震后能自动或通过加热(通电)复位;③利用形状记忆合金的强度和弹性模量使得隔震支座的竖向抗拔能力得到提高,并且限制了支座在振动时的最大位移。Seismic isolation is the earliest passive control method studied and applied at home and abroad, and a large number of experimental studies, actual engineering construction and multiple strong earthquake tests have proved that seismic isolation can greatly reduce the seismic response of civil engineering structures. A general seismic isolation system must have the following characteristics: bearing characteristics, seismic isolation characteristics, reset characteristics, damping and energy dissipation characteristics, and stability and durability. Shape memory alloy (Shape Memory Alloy, SMA) is an important intelligent material, which has the advantages of good fatigue resistance, strong damping ability, large recoverable deformation and stable performance. At present, the idea of using SMA for structural isolation is mainly to combine shape memory alloy materials with conventional isolation devices: ① Utilize the high damping characteristics of shape memory alloys to improve the energy dissipation capacity of isolation bearings; ② use shape memory The shape memory effect or superelastic effect of the alloy enables the bearing to reset automatically or by heating (energizing) after the earthquake; ③Using the strength and elastic modulus of the shape memory alloy can improve the vertical pullout resistance of the seismic isolation bearing, And limit the maximum displacement of the bearing during vibration.
已经开发的各类隔震装置大多仅仅起到水平向的隔震作用,不能起到水平和竖向同时隔离的作用。然而,大量的实际震害表明,竖向地震对于土木工程结构的破坏是不容忽视的。因此,非常有必要开发能够同时隔离水平和竖向地震作用的隔震装置。Most of the various seismic isolation devices that have been developed only play the role of horizontal seismic isolation, and cannot play the role of simultaneous horizontal and vertical isolation. However, a large number of actual earthquake damage shows that the damage to civil engineering structures caused by vertical earthquakes cannot be ignored. Therefore, it is very necessary to develop seismic isolation devices that can simultaneously isolate horizontal and vertical seismic actions.
