Structural Analysis of Complex Aluminum Alloy Structural Component Xiaowei Yin1, Wenxue Qian2a and Liyang Xie2 1 Department of Mechanical Engineering, Shenyang Institute of Engineering, Shenyang 110136, China, 2 School of Mechanical Engineering & Automation, Northeastern University, Shenyang 110819, China, aqwx99@163.com Keywords: Structural analysis, Finite element method, Aluminum alloy structure Abstract.
Aluminum alloy structures are widely used in engineering practice.
The FEM originated from the need for solving complex structural analysis problems in civil and aeronautical engineering.
Clough in the 1960s for use in civil engineering By late 1950s, the key concepts of stiffness matrix and element assembly existed essentially in the form used today and NASA issued request for proposals for the development of the finite element software NASTRAN in 1965.
The method was provided with a rigorous mathematical foundation in 1973 with the publication of Strang and Fix's An Analysis of The Finite Element Method, and has since been generalized into a branch of applied mathematics for numerical modeling of physical systems in a wide variety of engineering disciplines, such as thermodynamics and fluid dynamics[7-10].

In the 1950s to 1970s, our country construct many national and air defense engineering, many scholars study the underground engineering heat transfer to meet the needs of the project construction.
Precise dynamically calculate the heat transfer capacity of the envelope engineering, in order to achieve the dynamic simulation of the air conditioning load of underground engineering.
The underground engineering envelope wide is 6m, the buried underground depth is 5.3m, the thickness of the envelope is 0.5m, the length is 12m, the engineering around is light clay, the material of the envelope is reinforced concrete.

The research provides technology supports for life prediction and engineering application of the shock absorber.
The current study on the fatigue failure of civil engineering are concentrated in high cycle fatigue such as the cumulative damage and fatigue life evaluation.
Furthermore, the research provides technology supports for life prediction and engineering application of the shock absorber.

Experimental study on simply supported reinforced concrete after fire Han Xiao 1, a, ZhaoDongfu 2,b , You Zuokai 3,c 1 Beijing Institute of Civil Engineering and Architecture,China 2 Beijing Institute of Civil Engineering and Architecture,China 3 Beijing Institute of Civil Engineering and Architecture,China ahanhan20100225@126.com, bzhaodongfu@bucea.edu.cn, cyzk0816@163.com Keywords: reinforcement after a disaster; stiffness; damage Abstract.
According to the national construction engineering quality supervision and inspection center of an engineering structure's inspection report, the main fire damage grade level 1 is for 1, 3, 4, 6layers, 26 E and 28 layers of building floors; the secondary Fire damage grades is for 19, 20, 24, 26A layers; Fire damage gradelevel 3 is for 2, 5 , 7 ~ 13, 15, 17, 26D and 27 layers.
To facilitate the engineering practice for flexural stiffness of concrete beam after fire, we use the width folded subtraction stiffness calculation.
