摘要
Abstract
The concrete cooling tower of Shenhua Shengli Power Plant is located in the 7 degree seismic fortifica-tion zone,with a height of 225 m and a hyperbolic cylinder.Once the super large cooling tower is destroyed un-der extreme load such as earthquakes,the consequences will be catastrophic.At present,the research on cool-ing tower is mainly based on numerical simulation,and the experimental research is few.By designing and car-rying out a seismic shaking table model test with a scale ratio of 1∶33,the structural dynamic response character-istics of the cooling tower are studied,the stiffness degradation and damage of the structure under different seis-mic intensities are analyzed,the weak parts of the structure are found.Considering the results of dynamic test and numerical simulation,the reliability of the structure is evaluated,and reasonable anti-seismic measures and structural suggestions are put forward.关键词
