The importance of earthquake occurrence and bridge abutment rubber bearings [grid]: the countries in the world to implement the existing building architecture, confrontation with the seismic shock, Yingkang (anti-death) of the internal forces tied earthquake architecture. From a fundamental principle to analyze the structure of dynamic equilibrium, static balance this confrontation with the seismic force structure system completely destroyed in the earthquake. In other words, the existing building architecture, only to meet the balance of action and reaction static (no seismic shock) under the conditions. When the earthquake erupted, static equilibrium structure forces the building was destroyed. This is the current building structural systems can not resist the root cause of the earthquake impact damage lies. Seismic design of the existing building structure, but increased just change the building structure to increase the impact of the earthquake confrontation force (dead resistance) without the structure dynamics. [Grid] manufacturers of finished rubber bearing a big promotion! For centuries the building bearing the human pursued static (increased stiffness) of the building architecture, contrary to the objective laws of the earth quake. Therefore, for the man himself caused a huge disaster. Humans on Earth in order to better survive and develop, you have to adapt to a fundamental solution to the earth quake building structural system of objective laws. Therefore, a mechanical theory compatible with seismic force, "the release of internal forces of structures earthquake homeostasis system" dynamic equilibrium is established, and to develop new structures to release seismic shock design criteria (not standard in the confrontation) will be the direction and goals of human development. [Grid] elaborate rubber bearings recommended! Internal force equilibrium phase Earth: Earth structure, and processes in the rotation around the sun revolving movement, internal forces generated by the rubber bearing construction, in equilibrium phase, ground motion in the internal forces balance, earth movement is at a standstill, this stage may like Earth inertial reference system for the stage. [Grid] rubber bearings and reliable quality! [Grid] build bridges rubber bearing in the earthquake zone, to make it possible earthquakes have adequate security, and ease of repair or mitigate the damage to the bridge seismic studies. Its contents include macroeconomic survey damage to bridges, seismic design and seismic measures to bridge structure. Bridge Damage [Edit this paragraph] grid rubber bearings frequent earthquakes, according to statistics of the world up to several million times a year, but most of them are small earthquakes, no feeling for people, only a very small magnitude M ( See seismic intensity) was a strong earthquake in five or more will cause disaster, only a dozen times a year on average. Such as China at 3:42:56 on July 28th, 1976 in a strong earthquake in Tangshan Feng South (M = 7.8) building bearing damping, moderate damage to the highway bridge span simply supported beam-column support are mostly swing Block dumping, fixed bearing tooth plate cut off the slide, some piers tilt column pier piles of piles of broken beams and even falling down pier (see figure); and flexible pier damage hyperbolic continuous arch more the main arch and arch building a small arch severe cracking individual has the main arch arch and serious damage. [Grid] uses rubber bearings find Guangrun rubber bearing [grid] railway bridge pier foundation in the region due to better lateral stiffness is strong, serious damage to a lesser extent than the road bridge, such as along the pier construction cracking at the seams or cut steel bearing anchor bolt is pulled out and shifted, but fewer incidents off the beam. Many earthquakes in other countries such as Japan, bridge damage also to small and medium span bridges as much. Japan in July 1964 when the Niigata earthquake (M = 7.5), due to the riverbed Showa Bridge pier foundation soil liquefaction cause massive sinking off the beam.
