Abstract: Based on presented novel no-through-core concrete-filled steel tubular connection with flat beams with dense ribs, static experiments on typical connections have been fulfilled. The experimental scheme, fabrication of specimens, loading system, development of cracks and failure models are described. Experimental results show that the design of the novel connection is reasonable, force transmission is clear and it is easy to be constructed. The usage of the novel connection will reduce the space around connection, thus its economical for the highrise building to adopt the novel connection.
Keywords: high-rise building; concrete filled tubular column; non-through-core connection; static experiment
