Study of Stiffness Calculation Method on Reinforced Concrete Beam Strengthened with CFRP Xue Han 1, a, Zheng Liu2, b, Xin Xu3,c and Chao Ge3,c Faculty of Civil and Architectural Engineering, Kunming University of Science and Technology Kunming, Yunnan, 650500, China a442046768@qq.com, bkmliuzheng@yahoo.com.cn, c197327216@qq.com, c 554311285@qq.com Keywords: reinforced concrete beam, CFRP, strengthen, short-term stiffness Abstract: The beam member should not only meet the requirement of carrying capacity but also has the ability to resist deformation.
The constitutive relations of the material are as follows: First, the stress-strain relationship of concrete recommended in the concrete specification is used.
Therefore the physical relationship of these three materials can be expressed as: (2) (3) (4) Equilibrium relationship of internal force on the section.

Experiment Starting materials were Bi2O3 (99.5%), TiO2 (99.5%), NaCl (99%) and KCl (99%) with analytical purity.
Raw materials mentioned above were mixed by ball-milling with zirconia balls as the grinding media in ethanol for 12h, and dried at 80˚C.
In order to prepare large BIT particles, excessive Bi2O3 were introduced into raw materials of BIT3 composition.
