| 摘 要： | 以模型试验的相似关系为基础,设计并制作一模型相似比为1/10的古塔模型结构,并对该模型进行了地震模拟振动台试验,测试其受震前后的动力特性变化,了解其刚度变化情况.同时测试了该模型结构在3种选定地震波作用下的加速度反应、位移反应;确定了相应的动力放大系数、最大加速度包络图、最大位移包络图;考察了相应的裂缝出现与发展情况以及薄弱部位的变形情况;最后根据试验结果,评判模型结构的地震反应机理和规律,评价结构的总体抗震性能,为古塔原型结构抗震保护提供了设计和构造建议. |

| Abstract: | Based on the similar relation of model experiments, a model structure of mosque pagoda with a similar coefficient of 1/10 is designed and fabricated. Earthquake simulating shaking table tests are performed on the model structure of pagoda to testing its dynamic characteristic and master its stiffness changes. At the same time the acceleration response and displacement response of the model structure are tested under the action of 3 selected seismic waves. Then, the corresponding dynamic magnification factor, maximum acceleration envelope, maxi- mum displacement envelope are determined, and corresponding cracks and development situation and weak parts of the deformation arc investigated. Finally according to the test results, structural seismic response mechanism and law of model and the Overall structure seismic performance are evaluated as structural seismic protection suggestions for pagoda prototype of design and construction. |
