弧形耗能器加固震损木构架抗震性能研究

基于榫卯节点木构架具有优良的抗震性能,开展参数化弧形耗能器加固榫卯节点木构架抗震性能试验研究。对震损后的榫卯节点木构架试件用不同厚度、半径的弧形耗能器进行加固,并研究其加固后的抗震性能,对比加固前后试件的抗震性能指标,确定相同尺寸弧形耗能器对不同尺寸木构架的加固效果,不同尺寸弧形耗能器对相同尺寸木构架的加固效果。

Experimental Study on Seismic Performance of Damaged Wooden Structures Reinforced with Curved Steel Dampers

The mortise-tenon joint wooden frames have excellent seismic performance. This paper conducts experimental study on the seismic performances of the damaged mortise-tenon joint wooden frames after reinforced with parametric curved steel dampers. The specimens, used in the previous tests, are respectively reinforced by curved steel dampers with different radius and different thickness whose seismic performances after reinforcements are studied. Compared with seismic performances before and after reinforcement, the consolidated effect of the curved steel dampers of the same size to the wooden frames of different size and that of the curved steel dampers of the different size to the wooden frames of the same size are established.
