000011146 520__ $$2eng$$aIn recent years, in conjunction with developments of supplemental passive energy absorption devices , the idea of buckling of thin-walled tube and the use of this property as an accordion metallic damper (AMD) as a valid seismic energy absorption damper was entertained throughout the scientific world. Extremely good behavior for seismic damping has been resulted and shown for the AMD's. For the purpose of improvements on AMD's , filled accordion metallic dampers (FAMD) are introduced and analytically and experimentally investigated in this paper. First analytical studies have lunched on FAMD's for identification of their behavior under axial cyclic loads. After specifying the preliminary material properties, a series of AMD's and FAMD's filled by polymeric foam were subjected to dynamic tension and compression. Based on the results obtained, using the appropriate filling inside the AMD's is a suitable technique for the purpose of improvement some of important specification such as the number of cycle before failure, amount of dissipated energy, plastic tension and pressure capacity and the effect of interaction between foam and accordion thin walled tubes plays a major role for this purpose specially in low capacity AMD's. This paper will provide the analytical and experimental investigations as well as promising results obtained during testing for potential use in seismic resistant construction.
