Based　on　the　Graesser＇s　constitutive　relations　of　shape　memory　alloy,　a　theoretical　model　for　hysteretic　behavior　of　the　SMA-rubber　bearing　is　established.　By　making　numerical　calculation　with　this　model,　we　got　the　smooth　and　approximate　bilinear　force-displacement　curves　which　are　similar　to　those　exhibited　by　the　laminated　rubber　bearings　with　elastic-plastic　hysteretic　mechanism.　After　that,　the　predicted　responses　from　the　model　match　closely　the　experimental　results.　Meantime,　the　results　show　that　the　SMA-rubber　bearing　displays　an　evident　hysteretic　effect,　which　can　be　used　to　limit　the　extent　of　bearing　displacement.
