    A novel FBG sensor based on spoke-structure pressure box by utilizing FBG as the element sensing component is presented. Under room temperature,within the range of 0~30KN,its linearity and sensitivity reaches 99.91% and 22 N,respectively. Furthermore,it has excellent repeatability and high response speed. Compared with other FBG sensors,the spoke FBG sensor has wider measurement range and higher interference resistance. In addition,owing to its applicability for WDM systems,sensing networks can be constructed by FBG sensor to measure multi-point and many physical parameters. This research demonstrates that the designed sensing system has the advantages of simple and compact structure,easiness for manufacture,little delay time,good repeatability,light weight,etc. And it will have various applications in the fields of monitoring large buildings such as bridges,mansions and mass scale tunnels.
