摘　　要：随着铝合金结构在我国的应用和发展,其高温性能研究不足的问题日益凸显。节点作为整体结构的重要部分,其高温性能至关重要。实际工程中铝合金构件多采用不锈钢螺栓连接。总结了近年来国内外高温下铝合金、不锈钢材料性能研究,以及常温下铝合金构件螺栓连接的承载性能研究,为高温下铝合金构件不锈钢螺栓连接的承载性能研究提供建议。With the application and development of aluminum alloy structures,the problem caused by the deficiency of fire performance research on aluminum alloy structures becomes increasingly prominent.As the connections being the important part of the whole structure,the mechanical behavior of connections at high temperatures has a great impact on the fire performance of the whole structure.At present,the stainless steel bolted joint is the most common form of connections in practical engineering as connection for aluminum alloy structure.The state-of-the-art of research on the mechanical behavior of this connection are introduced in this paper,including the research on material properties of aluminum alloy and stainless steel at elevated temperatures and the bearing capacity of the stainless steel bolted joints for aluminum alloy members at room temperature.The suggestions on the research of stainless steel bolted joint for aluminum alloy members at elevated temperatures are presented at the end of this paper.
