Abstract
In this experimental study, the statical characteristics of WF beam-to-SHS column connections using special shaped high strength bolts called "Paddle Bolt" was investigated. Because the method of construction does not use welding for connection, execution efficiency is better than a through diaphragm type. Bending out of plane of column flange in connection influences elastic stiffness of connection. Tested it with cruciform specimens based on conventional findings, and was aimed for practical use of connection. From the results of this test, flexural strength of connection was able to be almost evaluated with prediction formula by a yield line theory.
