The Reinforcement Design of Special Vertical Irregular Steel-Concrete Composite Structure Fankui Zeng1,a, Changming Hu2,b, Xingcai Liu2,c 1College of Architectural engineering, Qingdao Agriculture University, Qingdao, China 2School of Civil engineering ,Xi’an University of Architecture and Technology, Xi’an, China afankuizeng@126.com, bhu.tm@163.com Keywords: Composite Structure; Structural Cracks; Steel Reinforcement; Reinforcement Abstract.
In order to make some improvement, we use bolt connection run throng the wall body instead of steel belt and steel bone welding, which will make the transmission of the structure more clear, shorten the construction period and ensure the engineering quality effectively.
Reinforcement of combination of structural engineering in the construction like Palms together dagoda in the Famen Monastery, has rarely been reported at home or abroad.
After the re-design for the nodes, we use bolt connection run throng the wall body instead of steel belt and steel bone welding, which will make the transmission of the structure more clear, shorten the construction period and ensure the engineering quality effectively.

Finally,simulation is carried out with an real aircraft fuel tank, comparison between simulation results and test data shows that relative error of pretreated fuel tank volume model is less than 1%, which satisfies engineering requirements.
Civil and transport aircraft usually adopt integral structure fuel tank and take wings as the main fuel storage space.
For engineering applications, a common practice is to generate database consist of fuel level -fuel surface angle - fuel volume - fuel quality property parameters and then store it in the onboard fuel management computer.
When the remaining fuel mass was greater than 40% of full-tank fuel volume, the relative error was less than 1%, which satisfied engineering requirements.

Excavation Type Optimization of High Cutting Slope at Reservoir Bank Huafeng Deng1, a, Yu Wang2,b, Min Zhu3,c and Jing Guo4,d 1, 2, 3, 4 College of Civil Engineering & Architecture, China Three Gorges University, Yichang 443002, China adhf8010@126.com, b45782699@qq.com, czhumin2006105131@126.com, dshowseal@yahoo.cn Keywords: high cutting slope; excavation type; optimization; reservoir bank Abstract.
Because our country is a mountainous country, in engineering construction process, inevitably involve a lot of high cutting slopes.

The key characteristic of COG is that it contains H2 and CH4, and the calorific value is 17000J/m3, eventually high enough to civil usage.
For example, civil gas should be pure COG.
Generally, the model is a Multi-Objective Nonlinear Programming Problems (MONLP) Theory Study of Gas Scheduling Model Assignment Problem (AP) is a typical problem of combinatorial optimization, and used widely in the science, technology and engineering.
