wo reinforced concrete frame models,one with energy-dissipation bracings and the other without bracing,have been tested on shaking table for comparison.The failure modes and dynamic characteristics of these two kinds of frame structures under earthquake excitations are studied.The test and non-linear time history dynamic analysis show the superior aseismic performance of the frame with energy-dissipation bracings.The non-linear time history dynamic analysis of the main frame structure of Yangzhou Power Plant shows that the frame with energy-dissipation bracings has better aseismic behavior than the frame with common bracings and can be proposed for practical use.
