Abstract:

Twenty-three steel portal-frame knee connections were subjected to uniformly distributed static and dynamic loads along one leg of the connections. Three types of connections square, curved, and tapered haunch knees were tested in each of two loading configurations. The load was applied so that the inner flange of the connection was either in tension or compression. The connections were designed to join wide-flange steel sections about 16 in. in depth at an angle of 90 degrees each leg of the members was approximately 9 ft. long. The detailed results of the tests are evaluated, and comparisons are made of the various connections in regard to energy-absorbing capacity, stiffness, ductility, rotational capacity, and development of the fully plastic yield moment in the wide-flange beam. Measurements of pressure, deflection, reaction, strain, and acceleration are tabulated and the static and dynamic behavior of the connections is plotted graphically. Theoretical static and dynamic analyses of various connections and loading conditions are presented. Author
