摩(mo)擦滑(hua)移(yi)隔(ge)(ge)震是(shi)開發應用較早的(de)(de)隔(ge)(ge)振技術之一，所用的(de)(de)摩(mo)擦材(cai)(cai)料多(duo)為(wei)沙(sha)石(shi)、石(shi)墨等廉價材(cai)(cai)料，標記經濟(ji)且簡單易行。摩(mo)擦滑(hua)移(yi)隔(ge)(ge)震系統(tong)(tong)通常有(you)隔(ge)(ge)離地震作用的(de)(de)摩(mo)擦滑(hua)動(dong)機(ji)構(gou)和限(xian)位復(fu)(fu)位的(de)(de)阻尼向心(xin)機(ji)構(gou)組(zu)成(cheng)，多(duo)為(wei)平面滑(hua)移(yi)隔(ge)(ge)震系統(tong)(tong)。該系統(tong)(tong)不能(neng)自(zi)動(dong)復(fu)(fu)位，一般需要另外加設復(fu)(fu)位裝(zhuang)置(zhi)(zhi)，且滑(hua)動(dong)性能(neng)離散性大、不易控(kong)制(zhi)，滑(hua)移(yi)量過(guo)大可能(neng)導致穿越隔(ge)(ge)震層的(de)(de)非結構(gou)構(gou)件(jian)破壞，甚至可能(neng)發生滑(hua)移(yi)失穩(wen)，這極大地阻礙了(le)(le)(le)滑(hua)移(yi)隔(ge)(ge)震的(de)(de)發展(zhan)。為(wei)了(le)(le)(le)解決平面滑(hua)移(yi)系統(tong)(tong)不能(neng)自(zi)動(dong)復(fu)(fu)位問題，Zayas等于1985年在美(mei)國加州大學伯(bo)克(ke)利分校研發了(le)(le)(le)摩(mo)擦擺(bai)隔(ge)(ge)震裝(zhuang)置(zhi)(zhi)，稱之為(wei)摩(mo)擦擺(bai)系統(tong)(tong)/支座(Friction Pendilum System/Bearing,簡稱FPS/FPB)。該裝(zhuang)置(zhi)(zhi)不僅具(ju)有(you)平面滑(hua)移(yi)隔(ge)(ge)震裝(zhuang)置(zhi)(zhi)的(de)(de)對地震激勵(li)頻率范圍的(de)(de)低敏感(gan)性和高(gao)穩(wen)定性，特有(you)的(de)(de)圓(yuan)弧滑(hua)動(dong)面還使(shi)其具(ju)有(you)復(fu)(fu)位功(gong)能(neng)，無需附設阻尼向心(xin)機(ji)構(gou)，故而在實際應用中更為(wei)簡便，且增加了(le)(le)(le)隔(ge)(ge)震裝(zhuang)置(zhi)(zhi)的(de)(de)可靠度。
摩(mo)擦擺(bai)隔(ge)震(zhen)支(zhi)(zhi)座(zuo)是將傳統的平面(mian)(mian)(mian)滑(hua)(hua)(hua)(hua)(hua)(hua)移(yi)隔(ge)震(zhen)裝置的摩(mo)擦滑(hua)(hua)(hua)(hua)(hua)(hua)移(yi)面(mian)(mian)(mian)由平面(mian)(mian)(mian)改為球面(mian)(mian)(mian)，從而可(ke)依靠自(zi)身重(zhong)力(li)自(zi)動(dong)(dong)(dong)(dong)回復。該支(zhi)(zhi)座(zuo)主要由上(shang)(shang)(shang)、下支(zhi)(zhi)座(zuo)板和一個鉸接滑(hua)(hua)(hua)(hua)(hua)(hua)塊組(zu)成(cheng)。摩(mo)擦擺(bai)隔(ge)震(zhen)支(zhi)(zhi)座(zuo)嵌在(zai)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)容腔中(zhong)的鉸接滑(hua)(hua)(hua)(hua)(hua)(hua)塊與(yu)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)面(mian)(mian)(mian)具(ju)有(you)相同的曲率半(ban)徑(jing)，可(ke)與(yu)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)面(mian)(mian)(mian)完全貼合，并使(shi)上(shang)(shang)(shang)支(zhi)(zhi)座(zuo)在(zai)支(zhi)(zhi)座(zuo)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)時(shi)(shi)始終保持水(shui)平。滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)面(mian)(mian)(mian)上(shang)(shang)(shang)涂(tu)有(you)低摩(mo)擦材料，如聚四氟(fu)乙烯(xi)（特氟(fu)龍(long)）等，可(ke)在(zai)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)過程中(zhong)耗(hao)散能量(liang)。當滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)界面(mian)(mian)(mian)受(shou)到(dao)的地震(zhen)作用超過靜摩(mo)擦力(li)時(shi)(shi)，地面(mian)(mian)(mian)水(shui)平運動(dong)(dong)(dong)(dong)會(hui)促(cu)使(shi)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)在(zai)其圓弧面(mian)(mian)(mian)內(nei)滑(hua)(hua)(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)，從而迫使(shi)上(shang)(shang)(shang)部結構輕微抬高，發生(sheng)單(dan)擺(bai)運動(dong)(dong)(dong)(dong)。然后，支(zhi)(zhi)座(zuo)會(hui)在(zai)自(zi)身受(shou)到(dao)的豎(shu)向(xiang)荷(he)載作用下自(zi)動(dong)(dong)(dong)(dong)回復。
摩擦(ca)(ca)擺隔(ge)震(zhen)支(zhi)座(zuo)(zuo)的(de)(de)水平力(li)(li)(li)為滑(hua)動面摩擦(ca)(ca)力(li)(li)(li)和(he)上部結(jie)構沿滑(hua)道上升產生的(de)(de)恢(hui)復(fu)力(li)(li)(li)的(de)(de)合(he)(he)力(li)(li)(li)，而提供的(de)(de)恢(hui)復(fu)力(li)(li)(li)使(shi)支(zhi)座(zuo)(zuo)能(neng)依靠其承受的(de)(de)重(zhong)力(li)(li)(li)自動往(wang)中心(xin)位(wei)置回(hui)復(fu)，使(shi)地震(zhen)響應得到控(kong)制，并(bing)且該支(zhi)座(zuo)(zuo)的(de)(de)剛(gang)度(du)中心(xin)有自動與(yu)隔(ge)震(zhen)結(jie)構的(de)(de)質心(xin)重(zhong)合(he)(he)的(de)(de)趨勢，因而能(neng)在(zai)更大 程度(du)上消除結(jie)構的(de)(de)扭轉運動。摩擦(ca)(ca)擺隔(ge)震(zhen)支(zhi)座(zuo)(zuo)的(de)(de)周期、豎(shu)向承載(zai)力(li)(li)(li)、阻尼比、側(ce)重(zhong)位(wei)移和(he)抗拉力(li)(li)(li)等指(zhi)標可以(yi)進(jin)行(xing)單獨(du)控(kong)制，該特性十分便于設計人(ren)員對隔(ge)震(zhen)系統進(jin)行(xing)優化設計。
