Relation Between Damage of Unreinforced Masonry Walls and Their Natural Frequency

  • 발행 : 2006.05.11

초록

The objective of this study is to evaluate residual seismic capacity of Unreinforced Masonry(URM) walls which were damaged by earthquake through the measurement of frequency. Three URM walls which made the shape ratio(1/h, 1.0, 1.5, 2.0)to be a variable were tested for the objective. It was seen that the natural frequency decreased with growing at rotation angle. Also, this study found out that residual seismic capacity and natural frequency of URM walls is correlative.
