Stability Study of Self-Balanced Prestressed Latticed Shell Structure with large span Guodong Li1, a Qingqing Li 1,b and Wancheng Liu 1,c 1College of Civil Engineering, Northeast Forestry University, Harbin 150040, China aldlgd@163.com, bzhunian1314@163.com, c2wcw@163.com Keywords: latticed shell, prestressed, self-balanced, structure stability Abstract.
Through the contrast analysis from buckling load, buckling modes, degree of prestress, different initial disfigurement in latticed shell structure, obtaining the disciplines that structure stability properties of the large span prestressed latticed shell, related conclusions to the engineering design of new latticed shell are instructive.
So the structure economic and artistic, it can realize large space engineering requirements.
(3) The buckling limit load of self-balance prestressed latticed shell structure is not less than 180kN/m2; it can guarantee the safety requirements of engineering structure.

After the indoor experiment, and 3 years of field experiments and experimental engineering, department of civil engineering of South China University of Technology (SCUT), has successfully studied the chloride-resistant high performance concrete (HPC) to resolve this problem [1-11].
And now this HPC have used in eight engineering successfully.
On the base of the experimental results and the experimental engineering, The Office of Water Resources of Guangdong Province edited the "Application technology guide for anti-seawater concrete of Guangdong province" to make sure the quality of the engineering and improve the durability of the engineering at the high chloride-ion concentration environment.
The cement used in testing the quality of admixture should be the same as that was used in engineering.
The water-binder ratio is chosen according to the compressive strength and the durability of the engineering.

Failure Analysis of Laminated Composites under In-plane Compressive Loading Yinhuan Yang 1, 2, a 1 School of Energy and Civil Engineering, Harbin University of Commerce, Harbin 150028, China 2 Center for Composite Materials, Harbin Institute of Technology, Harbin 150080, China ayinhuanyang@yahoo.com.cn Keywords: composite laminates; progressive failure analysis; material properties degradation Abstract.
A modified form of Hashin’s failure criterion by Shokrieh is used to detect the failure, where a sudden degradation model is proposed to reduce engineering material constants.
Accordingly, entire failure is taken for this element and all degradation engineering material constants are 0.

The phenomena that occur during high-speed penetration of a projectile into sand particles are interesting subjects in engineering.
Introduction The behavior of sand particles during high-speed penetration of a projectile is an interesting research subject in different areas in engineering.
Numerical simulation has become an increasingly important tool for solving complicated problems in engineering.
This method had originally been used for the simulation of the mechanical behavior of distinct particles such as granular materials in civil engineering.
The SPH method has been widely applied to simulations in areas such as fluid dynamics, thermal fluid dynamics, and impact engineering [5].

The three-dimensional element LINK8 is used in various engineering tasks.
