Abstract: Freight railroads contribute to the national economy by moving over 40% of intercity ton-miles of freight. Meanwhile, train accidents can damage infrastructure and rolling stock, disrupt operations, and possibly cause ...

Abstract: Against a background of various techniques for gust load alleviation (GLA), this paper aims at proposing an improved linear quadratic Gaussian (LQG) method, which is robust to variations of flight parameters, structural ...

Abstract: This study presents a numerical model to characterize the fracture process of a reinforced concrete (RC) beam strengthened with fiber-reinforced polymer (FRP) in detail. A numerical model based on the application of cohesive ...

Abstract: Freight train accidents can damage infrastructure and rolling stock, disrupt operations, and possibly cause casualties and harm the environment. Understanding accident risks associated with major accident causes is an ...

Abstract: This study aims to investigate the seismic performance and response of moderately damaged, rectangular hollow bridge pier specimens strengthened with carbon fiber–reinforced polymer (CFRP). For this purpose, two 1:8 ...

Abstract: Nonlinear time-history analyses are conducted on a flat-plate building to explore the damaging effects of vertical ground acceleration on punching shear failure of slab–column connections, which have been exposed by field ...

Abstract: Aside from aesthetic appearance, recycling, ease of disassembly, decent resistance against corrosion, and no intense moisture condensing and thermal bridge, compared with steel fasteners, wooden fasteners also have the ...

Abstract: Acting as a powerful oxidant, efficient coagulant, and effective disinfectant, ferrate is a good multifunctional agent for water and wastewater purification. In this study, some of these key aspects were studied for treating ...

Abstract: Broken rails are the most frequent cause of freight-train derailments in the United States. Consequently, reducing their occurrence is a high priority for the rail industry and the U.S. Federal Railroad Administration. ...

Abstract: Little attention has been paid to the fast-growing biohazardous wastewater (BHW) in recent years, even though it may pose severe biohazards and toxicity to the general public and environment. Two processes including Fenton ...
