SEISMIC PERFORMANCE OF WOODEN SEMI-RIGID FRAME WITH PRESTRESSED JOINT SYSTEM

This paper proposes a prestress-jointed wooden semi-rigid frame with wood/steel hybrid braces. First, an overview of the frame is given. Next, mechanical models of the braces, the column-beam joints, and the columns and braces joints are presented. Finally, static push-over analysis and earthquake response analysis are performed on one frame of the study building using the analytical model of the frame with the mechanical model in place. Equivalent damping constants, maximum response values, and energy absorption about four types of wooden semi-rigid frame structures are compared, and their seismic resistance is evaluated.
