Other mechanical performance testing indicators include shear aging resistance, shear bonding performance, etc. This article mainly discusses the testing process of ultimate compressive strength, compressive elastic modulus, and shear elastic modulus, and points out common problems and precautions in the testing.

Installation steps for bearings for prefabricated multi piece T-beam bridges

Materials and performance of seismic isolation bearing : The materials and performance of seismic isolation bearings directly affect the LRB service life. For example, seismic isolation bearings made of rubber materials, like lead rubber bearing, high damping rubber bearing,they have the characteristics of high damping,

Compared to traditional sealing methods, such as welding or installing piston valves, it is easier to plug air bags with pipes.
