| Abstract: | 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. |
