Research Progress And Prospect On Self-drilling Screw Connection Shear Capacity Linfeng Lu1, a, Yaping Zhang1,b , Wenqi Fang2,c and Donghua Yang3,d 1Key laboratory of Communications,Chang' an University,Xi'an,Shanxi,710061,China 2New era(Xi’an) design engineering Co.
North American AISI [6] gave the calculation and design methods of a single screw connection shear capacity on the base of summarizing, it has very important reference and learning for other countries in the world to develop the corresponding technical standards, to have relevant scientific research, and to design engineering.
Conclusion and Prospect With the high-strength cold-formed thin-wall steel widely being used into practical engineering, the possible of self-drilling screw being cut is increasing greatly, relevant professional and technical standards must be resolved in time.

Stability of Cable-Arch Structure KANG Hou Jun1, 2a, ZHAO Yue Yu1,b and ZHU Hai Ping2,c 1College of Civil Engineering, Hunan University, Changsha, Hunan 410082, China 2School of Engineering, University of Western Sydney, Penrith, NSW 2751, Australia akhjun@hnu.edu.cn, byyzhao@hnu.edu.cn, cH.
Cable-arch structure has been widely used in bridge engineering.
Therefore, the research about the stability of cable-arch structure are both valuable not only in theoretical research but also in design of engineering structure.
Thus, the stability like the dynamics of cable-arch structure is of great engineering significance.
Therefore, the cable-arch structure has a better static behavior than that of pure arch and this work is of significant meaning in theoretic research and design of engineering.
