Basic　concept,　damping　mechanism,　application　and　studying　status　of　particle　damping　technology　were　introduced.　Its　theoretical　analysis,　numerical　simulations　and　experimental　study　developments　were　systematically　presented.　A　discrete　element　method　for　simulating　a　multi-degree-of-freedom　(MDOF)　structure　with　a　particle　damper　system　was　illustrated.　The　application　of　particle　damping　technology　in　civil　engineering　and　its　study　situation　were　mainly　discussed,　its　advantages　and　potential　usages　were　demonstrated,　the　difficulties　and　deficiencies　in　the　present　studies　were　also　indicated,　and　some　suggestions　were　provided.
