This utility model belongs to the field of seismic isolation and vibration reduction technology for bridge structures, and specifically relates to a shear energy-dissipating steel truss connecting beam for replaceable railway piers. It includes several steel truss connecting beam units, spaced apart along the height of the pier column. At the same height position, there are four steel truss connecting beam units, each positioned between adjacent pier columns. Each steel truss connecting beam unit includes horizontally arranged upper and lower chords, and at least one set of intersecting diagonal web members between the upper and lower chords. The chords are structural members designed to prevent instability of the outer web members of the pier column. The web members mainly bear axial forces and reduce seismic response by dissipating energy through tensile and compressive deformation. This structure dissipates energy through plastic deformation and yielding, thereby protecting the pier column and achieving a graded energy dissipation effect. Furthermore, the steel truss connecting beam system is easy to replace after damage, and the replaced pier can immediately resume normal use, playing an important role in post-earthquake repair and operation of bridges.
