Analysis on the Mechanical Properties of Connections on Cold-Formed Square Steel Column and Beam Yong Yaoa , Yun-peng Chub School of Civil Engineering and Architecture, Southwest University of Science and Technology, Mian yang, Sichuan 621010; China ayy001221@163.com , bchuyunpeng@swust.edu.cn Keyword: Cold-Formed Square Steel Tubular; Welded Beam-Column Joint; Bearing Capacity; Ductility; Stiffness Abstract.
Material parameters and element of finite element analysis The steel type is Q235B, yield strength is 235MPa,Tensile strength is 380Mpa, assuming the materials are ideal elastic plasticity two line model, yield criterion and the hardening comply with the Von-Mises yield criterion and Bilinear-Kinemat (BKIN), Considering large deformation and large strain.
From the Fig 3 we can see: (1) under the static loading, all the joints experienced the elastic stage and elastic-plastic stage; because of material strengthened, the carrying capacity of component is improved, but the capacity increased obviously lagging deformation growth, and the QJ joint into plastic early, joint of GQJ has longer yield platform and better ductility than QJ.(2) As the increasing of axial compression ratio, the bearing capacity and stiffness of both two kinds of joints have been decreasing; under the same axial compression ratio, yield load and ultimate load of GQJ is 50% larger than QJ.(3) Under the same axial compression ratio, the initial stiffness of GQJ is larger than QJ, and the axial compression ratio has greater effect on the rate of stiffness degradation on QJ than GQJ.

The device should have the strength of rebar and the deformation capacity of Split Set bolts (Fig. 1), with the ability to be rapidly mobilized to a load level similar to the strength of the material.
The resistance is constant and close to the strength of the rod material.
Conclusions The new bolt utilizes the plastic properties of steel during drawing operations which is able to carry constant loads that is close to the strength of rod material.

When these formations are no larger than ~3 nm and intergrain distances are small, the interactions between grains are strong, which negatively affects the quality of materials for many applications.
The Fe(001)/Pd(001) bilayer structure was formed by sequential thermal deposition of Fe and Pd onto single-crystal MgO(001) substrates with the use of electron bombarding of crucibles with these materials in vacuum at a residual pressure of 10-6 Torr.

When the liner is integrated, a voltage impressed across the liner produces a relatively uniform voltage potential distribution in the materials above and below the liner [9, 10].
Therefore, leaks can be located by measuring the potential distribution patterns in the material above or below the liner.
