What Is a Bridge Bearing?

Bridge support is an important structural component connecting the superstructure and substructure of the bridge. It is located between the bridge and the padding stone. It can reliably transfer the load and deformation (displacement and rotation angle) of the superstructure of the bridge to the substructure of the bridge. Important power transmission device. There are two types of fixed support and movable support. Common support forms for bridge engineering include: linoleum or flat support, plate rubber support, ball support, steel support and special support.

Bridge supports are connected

A bridge or bridge is across a canyon, valley,

Pier (pier) is an architectural concept that refers to the columnar structure that supports the bridge and the two structures that support the bridge. Generally, the pier is square, but there are other shapes such as rectangle. In addition to supporting the bridge, the bridge piers must not be able to block the flow of water. Therefore, there must be a certain distance between each bridge pier, and many bridges are not provided with bridge piers. ^[1]

Structural mechanics is a branch of mechanics. The main research object is the structure composed of rods. It is a compulsory subject for students majoring in mechanics and civil engineering, and is used in the fields of construction and machinery manufacturing. The research content of structural mechanics includes the composition rules of the structure, the response of the structure under various effects (external forces, temperature effects, construction errors, and support deformation, etc.), including the internal forces (axial, shear, bending moment, torque). Calculation, displacement (linear displacement, angular displacement) calculation, and calculation of the dynamic response (natural vibration period, mode shape) of the structure under dynamic load. Its basic tasks include structural composition analysis, structural mechanics analysis and structural stability analysis. With the advancement of modern engineering technology and the development of electronic computers, the analysis of complex structures under various factors in engineering practice has put forward higher requirements for the development of structural mechanics theories and methods, and promoted the development of traditional classical structural mechanics There are two major branches: computational structural mechanics and conceptual structural mechanics.

There are usually three methods of analysis in structural mechanics: static method, dynamic method, energy method, force method, displacement method, and moment distribution method. The matrix displacement method derived from the displacement method later developed the finite element method, which became the use of computers The theoretical basis of structural calculations. ^[1]
