摘要
对一个1/2比例的六层大开间多孔砖砌体房屋分别处于弹性阶段、极限荷载时及破坏后三种状态下进行了动力特性测试;采用方法有锤击法和脉动法两种.用7T17(s)数据处理机进行分析,得到各状态下的频率、振型和阻尼比等动力参数;并分析了这些参数随房屋所处状态的变化.
The measurement of dynamic characteristics for a large model on 1/2 scale had been conducted for several stages by the method of ground pulse and hammer blow respectively. The model was a six-storey porous masonry structure with large bays. The stages were elastic stage, limit state and after failure etc. The frequency, vibration mode and damping coefficient of every stage are abtained by the use of 7T17(s) data processor. The results show that the dynamic coeffient changed with the stage of the structure.
