福建圆形土楼模型振动台试验研究

Study on shaking table test of circular Tulou model in Fujian

以福建圆形土楼"如升楼"的缩尺振动台模型为研究对象,对福建土楼在夯土材料、夯筑机具及夯筑工艺等方面做了简要说明.重点对结构模型的不同峰值加速度作用下的动力特性、位移反应及加速度、开裂和破坏过程做了详细分析.试验表明,福建土楼具有良好的抗震性能,在试验最后工况9度罕遇地震作用下,也并未出现倒塌或者将要倒塌的现象.

Taking the “Rusheng Lou” scale shaking table model, a kind of circular Tulou in Fujian as the research object this paper makes a brief description of Tulou^s rammed earth material wall machine and wall technology, and carries out a comprehensive analysis of the dynamic characteristics under different peak acceleration and displacement response and ac-celeration cracking and failure process of structural model. The result of the analysis shows that Fujian Tulou with a good seismic performance will stand the test of the severe earth-quake at nine degrees and cause no collapse to the model.
