000012177 520__ $$2eng$$aMeasuring on Yingxian wooden pagoda demonstrates that the torsional component of the residual deformation is distinct. After the two historic earthquake periods, the traces of broken damages become evident. The trials by conducting micro-tremor measurements of the tower, obtained the time-history curves of measuring points of each upper floor. Also, horizontal modes of vibration corresponding to different predominant frequencies of every upper floor are obtained from frequency spectrum analysis. Study on the horizontal mode discovers that translation-torsion coupling response of the floors is distinct, as well as relative torsion between layers. The phenomena are consistent with the residual torsional deformation. The torsional elastic earthquake response of each upper layer of the tower under different seismic waves is also calculated and analyzed.
