When utilizing the steel sandwich panel in ship structures,the proper connection is one of the key issues to be addressed. In this paper,the connection between steel sandwich panels,as well as the connections between steel sandwich panel and traditional hull structures are summarized. The necessity and significance of the steel sandwich panel joint are discussed,with the design requirements being ana-lyzed,including connection strength,manufacture convenience,and structure mass. The research achieve-ments on several typical joints of flat connection are also summarized. Two efficient analysis techniques, namely the plane strain model and the sub model of shell-solid assembly together,are finally presented.
