钢筋混凝土立筒群仓结构抗震模型的设计与制作
|
摘要
为了对目前应用较广泛却无规范可循的钢筋混凝土立筒群仓的抗震性能进行研究,根据相似理论对缩尺比例为1/16的立筒群仓模拟地震振动台试验模型进行了设计与制作。文中阐述了动力相似关系的确定原则、模型材料的选取以及模型施工等振动台试验的前期工作,以及如何根据具体情况解决在模型制作过程中遇到的问题。相关经验可为今后有关试验的模型设计及制作提供参考。
Reinforced concrete group silos is widely used in many industries nowadays,but we have no relatively detailed codes for its design and construction.In order to study the seismic behavior of the group silos through shaking table test,a 1/16 scale model of group silos was designed and constructed according to the similar theory.This article mainly focuses on the design work for shaking table test and illustrates similitude-scaling relationship,model material selection and the model construction in detail.There were some difficult problems in the process of model construction,but they were solved relatively smoothly after the problems were discussed by all the members of the project group.The success of model construction makes sure that the methods and experience in the design are right and feaible,which will provide some useful references for other similar experimental studies in future.
