Abstract |
Generally, aseismic elements used in buildings have high rigidity and yield strength, but conventional braced frame have instable elements subject to buckling. If high ductile and rigid elements are arranged properly, response of buildings can be controlled with rigidity of elements against small earthquakes or winds, and with hysteretic behavior against earthquakes. This paper presents the results of a test conducted for evaluating the structural behavior of steel-plate shear panels. A total of eight steel-plate shear panels were tested with the loading pattern (monotonous), aspect ratio (1.0, 1.5), and stiffener type (none, horizontal, cross, diagonal) as test parameters. The steel-plate shear panels buckled at a shear force. But, Plate buckling did not lead the shear panels to immediate degradation in their strength. Steel-plate shear panels with horizontal, cross, and diagonal stiffeners exhibited stable hysteresis and higher buckling strength. |
