| Abstract |
Today, peoples have much interest about safety while an abnormal weather phenomenon is weighted increased. R.C buildings are consisting of main loaded members. Concrete are brittle materials and they are which come to brittle fracture rapidly by progress of cracks. If a research trend present in and outside the country is often seen, the structure measurement method of having used PZT and the optical fiber (FBG) will be the actual condition which has accomplished the stock. In order to manage such cracks, time, efforts and expense are required. Such a method has many difficulties in application of a structure by the difficult problem of the measurement range, and the expensive sensor price. Progressive cracks were generated by fracture of glass pipe sensor. Moreover, the experiment which can detect damage propriety by external Light Emitting Diode by damaging a glass pipe by load change with the application of switch using strain gage of a glass pipe was conducted. |
