Abstract: A cylindrical assembled steel-lead damper includes at least two groups of cylindrical assembled steel-lead damper units, and each group of cylindrical assembled steel-lead damper units is connected in series. Each group of cylindrical assembled steel-lead damper units includes cylindrical energy dissipators and connectors; The cylindrical energy dissipator comprises a lead cylinder and a soft steel cylinder, the soft steel cylinder is sleeved outside the lead cylinder, and two ends of the cylindrical energy dissipator are provided with connecting pieces. The invention has the advantages and beneficial effects that the rigidity is high, the mild steel cylinder and the lead cylinder are well matched, the material utilization rate is high, and the energy consumption effect is good; During installation, prefabricated members are connected by bolts and nuts, and the damping can be adjusted as required, so that the assembly is convenient, the construction is simple, and the installation quality is controllable; Cylindrical energy-consuming components have good mechanical properties, can resist earthquakes in all directions and consume energy in different directions; It can be used not only for the seismic design of new building projects, but also for the reinforcement and maintenance of existing projects.
