| Abstract |
The bracket-type connection is often used for the weak axis steel connection of H-shape beam-to-column. However it leads to weakness of competitiveness in steel structure due to difficulty in production and installation of connection. Consequently, new shape weak-axis was developed. It has a simple shape with the less spot of welding points, and has advantage about showing the obvious power flow in connection points. In this study, monotonic and cyclic loading test in full-scale was performed to evaluate structural behavior and examine on-site application. Therefore, 12 specimens(9 specimens for monotonic loading test and 3 specimens for cyclic loading test) were built for the variables which are overlap length of beam-end and column flange. As the result, new shape of weak-axis connection appeared special Moment Frame(SMF) and had excellent structural performance and constructablility when the parameter is over 50mm. |
