By changing the internal force that main material of the cross arm suffered,deflection change of each main material occurred, resulting in fiber Bragg grating wavelength of the fiber Bragg grating strain sensors which on the surface of the cross arm shifting.
When meets adverse factors like the ice and other natural disasters, the stress of cross arm will increase, that may result in destruction of advocate or oblique material , and lead the cross arm to be destroyed.
We will install 4 sensors of the optical fiber Bragg grating cross arm stress of power tower, 2 at the center of the upper surface of 2 roots plane truss of the material and 2 at the center under the surface, which can real-time on-line monitor cross arm stress changes of power tower, and analyses the relevance between the stress and wind with local climate factor.

Introduction The stress concentration problems are encountered frequently where a sudden change of geometric dimension or material property takes place in the engineering structures.
This is because the actual materials have their own microstructure and intrinsic length scale, and the steep strain gradient may occur where stress concentration occurs.
Material parameters used are: elastic modulus E=, poisson's ratio .

CTS has a highly reactive amino group is a useful material for various purposes such as ion-exchange [2].
Recently, CTS derivative bearing β-CD has received considerable attention because its adsorption behavior is different from those of natural CD and CTS materials [3, 4].
