High-Performance Fiber-Reinforced Cementitious Composite (HPFRCC) materials are among the new materials used in recent years and have drawn the attention of structure engineers. High tension resistance in comparison to regular concrete and high ability for energy depreciation are among the advantages of these materials. Passive yielding dampers have also attracted the attention of structure engineers. Steel dampers are among novel dampers which, in spite of simple structure, possess high performance in energy depreciation, plus other advantages, such as being replaceable after the quake, simple structure, possibility of installation in different positions in pipe form in reigning systems, … etc. The coming survey investigates the effect of strengthening and combining pipe dampers by using HPFRCC materials. The findings show that strengthening pipe dampers by HPFRCC materials could dramatically depreciate the amount of energy entering the system and boost the efficiency of pipe dampers.
