Abstract: With higher requirements in stiffness and strength, the running safety of high-speed railway bridges is more sensitive to structural damage. Compared with long steel hangers, short steel hangers sustain greater damage under ...

Abstract: Parameterizations in numerical models account for unresolved processes. These parameterizations are inherently difficult to construct and as such typically have notable imperfections. One approach to account for this ...

Abstract: The steel truss arch is an important structural type for high-speed railway bridges with long spans. The fatigue assessment of rigid hangers under long-term train loads is an important concern. In this study, the Nanjing ...

Abstract: In the late stage of exploiting heavy oil reservoirs with edge-bottom water, we are faced with problems such as high crude oil viscosity, channeling of bottom water, and rapid rise in water cut. To clarify the synergistic ...
