DESIGN PARAMETER OF SEMI-RIGID CONNECTIONS THROUGH STATIC STEEL FRAME ANALYSIS
In this paper, in order to obtain a rational design parameter involving the connection factor that can be used in Japan, a fundamental study about the characteristic of multi-storied steel frames with changes in the strength of the beam-to-column connections was performed via a static analysis. The beam-to-column connection is an external diaphragm. The strength of the connection was varied with the height of the external diaphragm. In order to formulate a design condition involving the connections, four parameters were defined. The main parameter is the connection factor, adopted when the small one changed to a large one, and a push-over static analysis with an earthquake load was conducted. From the analysis results, information about the availability of the use of semi-rigid frames in Japan was obtained. The optimum value of the parameter, when both the connections and beams yield, can also be obtained.
