Bridge Bearings Introduction AASHTO defines a bearing as a structural device that transmits loads while facilitating translation and/or rotation.1 In the past Caltrans has used a variety of bearings with varying degrees of success.These include rockers,rollers,pins,pots,steel girder hangers,PTFE/elastomeric,and elastomeric pads.Bridge Decks - an overview ScienceDirect TopicsWeiwei Lin,Teruhiko Yoda,in Bridge Engineering,2017.5.5 Waterproofing System.Bridge decks are vulnerable,subject to attack by water and chloride that can lead to deterioration and issues with longevity and durability of the bridge decks.The installation of an effective waterproofing membrane is therefore an essential part of bridge deck system in addition to the drainage system.Bridge Maintenance and Management A Look to thebridge maintenance and management and to look ahead to the challenges that this field will face in the 21st century.BRIDGE MANAGEMENT SYSTEMS Bridge owners today must make decisions pertaining to maintenance and improvements that take into account both funding constraints and the overall needs of the highway system.
Articulation is the term for the configuration of bridge supports and choice of structural bearings that provides the necessary restraints to the superstructure whilst at the same time providing freedom to some displacements and rotations in order to avoid unnecessary forces on both the superstructure and substructure due to constraint..A range of different bearing types is available.British Standard - Stalwart Technosource8 Railway bridge live load 40 8.1 General 40 8.2 Nominal loads 40 8.2.1 Type RU loading 40 8.2.2 Type RL loading 40 8.2.3 Dynamic effects 40 8.2.4 Dispersal of concentrated loads 41 8.2.5 Deck plates and similar local elements 42 8.2.6 Application of standard loadings 42 8.2.7 Lurching 42 8.2.8 Nosing 42 8.2.9 Centrifugal load 43 8.2.10 China A36 Q345b Ss400 Q245b Structural Steel H Beam Quality JIS G3101 SS400,SS400/JIS G3106 SM490,KS D3515 SM490 Size and Tolerance JIS G3192,KS D3502 Application of the H beam H beam is widely used in various building structure and engineering structure a).used for the plant,high-rise building construction b).used for the bridge,shipment building
