[Isolation] bearing spring rubber bearing isolation principle is to set up a spring rubber bearings in the building or structure, or a location on the substrate, forming a flexible spring utilization level of a flexible rubber bearing isolation layer, through this layer to absorb and dissipate earthquake energy to be concentrated in larger relative displacement of isolation layer expense, to prevent or mitigate seismic energy transfer to the upper structure, and natural vibration period of the building has been extended in order to reduce the upper part of the structure of the earthquake response, and ultimately reach the upper earthquake damage mitigation purposes. [stand] by comparing the seismic isolation effect and not isolated building isolated building, indicating the use of a spring rubber isolated structure has significant effect when isolation pad Isolators . Traditional seismic design of buildings dedicated to ensure that the structure itself has sufficient strength, stiffness and ductility, to achieve the purpose of earthquake disaster mitigation, and [isolation] building isolation rubber bearings spring bearing the unique use of rubber elasticity and damping structure and the use of a spring shape and mechanically stable and can withstand heavy loads and large deformation planted characteristics, take the spring and rubber stack, to ensure that the vertical direction and with sufficient load-bearing horizontal use rubber unique viscoelastic, [ Bearing Isolator] when an earthquake occurs through the energy of the earthquake damping rubber spring through the horizontal displacement, since the earthquake cycle prolong quality laminated rubber bearings quality building standards, thus effectively separating rubber seismic activity isolator, and ultimately achieve the purpose of shock absorption. [Bearing] rubber spring vibration isolation pad has a great vertical bearing capacity and great vertical compressive stiffness, while its smaller horizontal deformation stiffness Yunnan rubber bearings sold worldwide, the horizontal displacement limit value is larger It has a large enough initial stiffness to resist wind loads and minor earthquakes, when a strong earthquake occurs, but also flexible to slide freely, while the deformation is too large, the stiffness rise, with the protection and limit the role of the spring rubber isolation pads have greater ability to reset automatically instantaneous reset repeatedly earthquake. [Isolation] bearing the same time it can be a good durability, the general life in more than seventy years, far more than five years of the life of an ordinary civil building requirements, so spring rubber mat will be applied across a wide range of shock device. [Isolation] compared to the traditional seat of seismic measures, traditional seismic methods mainly by plastic deformation of the main structural members after yielding energy and hysteretic energy to dissipate seismic energy, which makes the energy performance of these regions becomes particularly important and energy dissipation capacity depends on the ductility of the main structure of these areas, which requires both the main structure of sufficient strength and good ductility, it is difficult to achieve, and once as a result of certain factors lead to problems in these areas, will seriously affect the seismic performance of the structure, resulting in serious damage, and will result in significant casualties. [] traditional seismic isolation bearing structure is to prevent structural collapse rubber bearings for the target building new products, the seismic performance relies heavily on the structure (components) ductility, this approach focuses on improving the structure (components) ductility aspect, but ignored the extent of structural damage control, which has a lot of deficiencies. Also due to take the traditional site of the destruction caused by seismic methods are mainly located in an important structural component, which is difficult to repair the multilayer rubber bearings large supply of rubber bearings _ _ manufacturers sell low-priced works by Hengshui Guangrun Rubber Limited.
