Steel truss bearing raw data collation and preservation, master design conditions bearing steel grid construction and installation of steel bearing steel grid condition, changes occurred in the past and repair records information such as a full-bridge universal rotation spherical truss steel bearings, bearing steel grid function to understand the status and degree of variation, selection and method of repair time, though is a very complicated, complex and its important maintenance work, but this is a guiding significance for the future management of valuable information, so I hope the information bridge full bridge design conditions and when completed will be collected and collated and reflected in future maintenance and management, and will resume these data archives and in a relatively long period of time preserved is very important. These records should include the following: bridge name, including bridges form area, line names, including schematic diagram of the bridge structure. Bearing steel grid form, dunks bearing type truss steel bearings, steel truss bearing materials and layout and so on. Design conditions, including the steel truss bearing type, bearing materials and layout, and other design conditions, including the design of steel truss bearing reaction force, designed horizontal force, displacement, bearing characteristics and the use of standards and down steel center gap when the temperature conditions and measuring the amount of grid bearing. Horizontal seismic load bearing steel grid structure on the upper part of the top surface generated pier combination 康维刚 degree, powered by a structure designed to calculate the elastic stiffness fundamental period of the bridge, the investigation considered the amplification factor, the total weight of the superstructure Union, important type correction factor, see the highway engineering seismic design specifications, horizontal seismic coefficient seismic loading pier, pier entities own weight Piers particle horizontal seismic load. Pier basic modal participation factor, the relative horizontal displacement of steel truss segment bearing piers fundamental mode at the center of gravity. Pier identity segment of gravity, the water level of seismic load, the upper structure on the top surface of the laminated rubber bearings produced horizontal seismic load. When the earthquake equivalent horizontal seismic coefficient, steel truss design bearing damping coefficient of damping design pier Xu plastic ball grid steel bi-bearing activities, when calculating the pier bending failure is determined by the formula, steel grid bearing damage occurs when the pier damage by bending to shear failure of the transitional destroy or reduce capital contribution of 1.0. reinforced concrete piers limit displacement, reinforced concrete roll yield displacement.
