✦ Synopsis

The moment-rotation relationships of semirigid steel beam-to-column connections including single and double web-angle connections and top-and seatangle connections with or without double web angle, are developed. The initial elastic stiffness and ultimate moment capacity of the connections are determined by a simple analytical procedure. The shape parameter is then determined by a least-square curve fitting with experimental tests in Purdue University's data bank. Using the initial connection stiffness, ultimate moment capacity, and shape parameter so obtained, a three-parameter power model adequate for representing the moment-rotation relationships of these connections. The power model is simple to use and provides a realistical representation of the actual moment-rotation behavior of each connection type with angles, and can be easily implemented in a secondorder frame analysis.
