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.

This invention discloses an enhanced energy-dissipating, thermally insulating, and decorative three-in-one exterior wall coupling beam, comprising: two dynamic compensation joint plates for contacting the wall limb, enabling relative rotation and sliding between the beam end and the wall limb under stress; and multiple continuous reinforcing bars, equally divided into two groups and distributed vertically, sequentially penetrating the two dynamic compensation joint plates. Each continuous reinforcing bar consists of two straight reinforcing bar segments and a bent reinforcing bar segment located between the two straight reinforcing bar segments, with both ends of the bent reinforcing bar segment connected to the corresponding straight reinforcing bar segment via reinforcing bar sleeves. This invention allows the coupling beam to dissipate energy early under minor earthquakes or wind loads through the dynamic compensation joint plates at the beam ends; under moderate to large earthquakes, it efficiently dissipates energy through the concentrated large deformation yielding of the bent reinforcing bar segments, while ensuring that damage is mainly confined to replaceable mid-span components; during post-earthquake repair, only the local mid-span area needs to be replaced to quickly restore structural function, achieving a balance between seismic performance and recoverability.
