砖拱楼盖房屋振动试验与分析
|
摘要
本文给出了矢跨比分别为1/10和1/6的两幢二层砖拱楼盖房屋模型的振动台试验结果。对整个模型房屋建立了弹性支承杆系力学模型,用频率响应法分析了模型的位移反应,导出了相应的频率响应函数,并对各阶段的模型刚度参数进行了讨论。对砖拱楼盖,采用拱框结构力学模型进行了自由振动分析,并探讨了局部振动和整体振动等同题。
The experimental results of the two models of the brick house with arch floor whose rise to span ratio is 1/10 and 1/6 respectively are given in this paper, and then a mechanical model with clastic support for the whole model house is established, its displacement response is analyzed by using frequency response function method, a corresponding frequency response function is derived, and model stiffness parameter for different stages is discussed. The free vibration analysis is conducted by using arch-frame structure model for brick arch floor, from this the local vibration and the whole vibration of the arch are studied.
