Structural Design and Mechanical Behavior Research of Aluminium Alloy Bridge Deck
There are increasing aluminum alloy buildings and bridges because aluminum alloy has more advantages such as light weight, high strength and corrosion resistance compared with steel and reinforced concrete. Aluminum alloy bridge deck was used to replace the old bridge deck in Smithfield Street bridge in 1933 for the first time. From then, many aluminum [...]
The Study on Geological Disaster in the North Slope of Qin Ling Mountains
With the implementation of the strategy for the development of the western regions, the issue of slope geological disaster prevention has been more prominent. On the North Slope of Qin Ling Mountains, due to locating in unique crust geodynamics environment and under the action of fault activities, long-term strong new tectonic movements and exogenetic force, [...]
The Variability of Frozen-soil Parameters and Its Applying in Slope Reliability Analysis
With the completing of the large construction projects in the western part, such as Qinghai-Tibet Railway project, West-East Gas Transmission Project and the South-North Water Diversion project works, a good opportunity was provided for us to research the engineering geology and geotechnical engineering in cold regions。Its research, particularly slope stability research, under freeze-thaw condition, was [...]
Analysis of Mechanical Characteristics of Concrete Filled Steel Tubular Arch Bridge with Inverse Bending Arch
Concrete filled steel tubular arch bridge with inverse bending arch is first emerge in china.This bridge style is very graceful and reasonable in structure.With the increase of our national power,people have more and more requirements in bridge aesthetics, concrete filled steel tubular arch bridge with inverse bending arch will get widely applied in engineering field.The [...]

The Stability Research of the Concrete-filled Steel Tube Arch Bridges
The concrete-filled steel tube arch bridges constitute a major component in the long-span bridge category because of its high carryring capacity, saving, low cost, aesthetics and better economic effect. However, arch bridges transmit the applied loads to axial force mainly, which makes arch bridge uniquely susceptible to buckling failure, especially with the slender arch ribs.First, [...]
Study on Stability and Economical Efficiency of AC Excited Hydrogenerator Unit Operation
ACEHU (AC Excited Hydrogenerator Unit) is a new type of hydro-electric power equipment, with the inverter power providing generator with symmetrical AC excitation, and the amplitude, frequency, and phase of the excitation voltage being controlled in accordance with the requirements. The size of the magnetic field excitation, the location of the rotor and the motor [...]

The Influence of the Joint Stiffness on the Stability of Single-layer Spherical Latticed Shells
Reticulated shell is a space structure system that is made up of members regularly arranged along a surface. Owing to prominent properties, such as reasonable mechanical properties, high rigidity, large-span space covering, and so on, it become a primary kind of structural types of large-span spatial structures. The span and size of latticed shells tend [...]
