摘要：

This　paper　presents　seismic　energy　dissipation　systems　in　recent　years,　and　introduces　the　new　SMA　energy　dissipation　braces.　The　control　effects　of　a　steel　frame　with　these　new　energy　dissipation　system　are　analyzed　with　the　finite　element　method.　The　results　indicate　that　the　top　floor　displacement,　acceleration　and　internal　rotation　of　the　structures　with　the　new　SMA　energy　dissipation　braces　decrease　obviously.　The　energy　dissipation　and　hysteretic　performance　also　are　calculated.　In　conclusion,　the　new　SMA　energy　dissipation　braces,　including　SMA-toggle-brace　and　SMA-scissors-brace　systems,　have　good　seismic　control　effects,　and　can　be　installed　easily.
