Abstract

The invention provides a novel beam-fall-preventing damper and a damping system comprising the novel beam-fall-preventing dampers and relates to the technical field of earthquake prevention and resistance. In order to solve the problems that an existing damper cannot simultaneously achieve damping energy dissipation and limiting functions and cannot prevent a beam body from being affected by the temperature and construction errors, the novel beam-fall-preventing damper comprises an oil damper, a straight-tooth steel hysteresis damper, a first connecting component and a second connecting component. One end of the oil damper is hinged to a connecting board on the top face of the straight-tooth steel hysteresis damper through the first connecting component. The second connecting component isused for hinging the other end of the oil damper to an application end. The damping system comprises the 2*N beam-fall-preventing dampers, every two of the 2*N beam-fall-preventing dampers are arranged in a set, the two beam-fall-preventing dampers in each set are in Y-shaped mirror symmetric distribution on a plane, and N is a positive integer. The novel beam-fall-preventing damper and the damping system are used for earthquake prevention and resistance in port engineering.

Description

technical field [0001] The invention relates to the technical field of anti-shock and anti-shock technology, more specifically, the damper technology. Background technique [0002] Pushed by the Indian continent, the Qinghai-Tibet Plateau has been uplifted rapidly since the late Mesozoic, becoming the most active region in the world for tectonic movements. Since the beginning of this century, M8.1 in Kunlun Mountains, M8.0 in Wenchuan, M8.1 in Nepal, M7.1 in Yushu, M7.0 in Lushan, M6.5 in Ludian, A series of strong earthquakes such as Jinggu M6.0 magnitude. To build the Sichuan-Tibet railway or highway, it is inevitable to cross the most active fault zones in China such as the Hengduan Mountains and the Xianshui River and the Anning River. Crossing seismically active faults will be the biggest challenge for railway or road bridges. The Wenchuan Earthquake in 2008 caused devastating damage to the epicenter and adjacent bridges. Fault motion will bring inertial motion (vib...
