Abstract |
Detail development and performance tests were conducted for the purpose of developing a damper system capable of lateral displacement control of existing frame structures. The development details are 1) ALD designed to prevent deformation of beams between columns and 2) AWD designed to control inter-story displacement. The non-reinforced BF specimen was used as a comparative study. The evaluation variables are failure mode, load-displacement curve, envelope curve, maximum strength, stiffness degradation and energy dissipation capacity. As a result, the seismic strengthening effect of ALD and AWD was confirmed. Also, it was confirmed that the method of restraining the column with the aramid sheet is superior to the improvement of the seismic performance.
