摘　　要：叠层橡胶隔震支座与钢筋混凝土结构或钢结构的连接非常简单而成熟,但与型钢混凝土(SRC)结构的连接非常复杂,现有资料中找不到做法。对叠层橡胶隔震支座与SRC柱脚的连接进行了研究,发现柱底预埋件的锚筋与SRC柱主筋及型钢柱底板冲突,导致叠层橡胶隔震支座与SRC柱连接困难,提出将柱主筋通过套筒与预埋钢板焊接取代锚筋,将型钢柱底板通过螺栓与预埋钢板连接,从而解决预埋件锚筋、柱主筋、型钢柱底板相互冲突的问题,然后遵循规范提出预埋钢板、锚筋、钢柱底板及连接螺栓的计算方法,并将此项连接应用于云南省博物馆新馆项目,解决了该工程中叠层橡胶隔震支座与SRC柱脚的连接问题。The connection between laminated rubber bearing isolators and reinforced concrete structure or steel structure is very simple and mature,but its connection with steel reinforced concrete（ SRC） structure is very complex and it is hard to find the method in existing data. The connection between laminated rubber bearing isolator and SRC column foot was studied. It is found that the anchor bar of embedded part at column bottom conflicted with SRC column reinforcement as well as bottom steel plate of the column. This resulted in connecting difficulties between laminated rubber bearing isolator and SRC column. The main column reinforcement was suggested to weld with embedded steel plate through the sleeve to replace the anchor bar,and bottom steel plate of the column was suggested to connect with embedded steel plate by the bolt,so as to solve the problem of collision of embedded anchor bar,main column reinforcement and bottom steel plate.Then the connection was applied in New Yunnan Provincial Museum according to the calculation methods for specificationpresented embedded steel plate,anchor bar,bottom plate of steel column and connection bolt. The connection problem of the laminated rubber bearing isolator and SRC column foot in the project was solved.
