| Abstract: | Field testings of the dynamic characteristics of an overhead steel truss inclined corridor for a sintering workshop were carried out and the causes of its lateral swing were also analyzed.The lateral swings of small amplitude occurred in the scope of the master frequency of the structure′s self\|oscillation due to the fact that the structure′s lateral self\|oscillation period is very close to the eigen period of in\|situ soil.Therefore the normal operations of the corridor can not be affected by the lateral swings. |
