Connections of structural steel casting have been widely used in tall buildings and large span structures in China since 2001, especially after the announcement of the Technical specification for application of connections of structural steel casting (CECS235) in 2008. In the past decade, new casting technology, mechanical properties, innovative joint configurations, refined finite element analytical method, high-tech erection method, as well as design criteria have been improved. Thus the current technical specification needs to be updated to incorporate these changes for better applications. Researchers at Tongji University, as chief editor of the specification, have been tracking the changes in casting materials, design methods and construction through project-based experiments and the third party consultation. This paper presents a review on recent studies and applications of cast steel joints in China: (i) introduces the current design guidelines CECS235 and its key problems to be updated; (ii) reviews on the major research developments on casting connections listed above (iii) the applications of casting connections in some landmark buildings are illustrated focused on their configurations.
