The　feasibility　of　design　and　construction　for　the　reaction　mass　of　earthquake　simulation　multiple　shaking　tables　is　important　component　in　the　whole　system,　and　can　directly　determine　the　working　performance　of　shaking　tables.　The　characteristics　of　design　and　construction　for　the　reaction　mass　of　earthquake　simulation　triple　shaking　tables　at　Fuzhou　University　were　introduced　and　analyzed.　The　requirements　for　the　reaction　mass　should　be　having　huge　mass　and　stiffness,　large　strength　and　precision,　as　well　as　having　negligible　effect　to　the　ambience.　It　is　expected　that　the　introduction　will　benefit　the　design　and　construction　of　the　multiple　shaking　table　facilities.
