Load Transfer Efficiency Based on Structural Deflection Assessment of the Precast Floating Track by Linh Vu, Yun Suk Kang

“…In this study, a Finite Element Method program (MIDAS CIVIL 2019) was used to analyze the load-carrying ability of structures under the train axle loads. After finishing the design, to understand more precisely about load transfer efficiency of this type of track, an assembly test (two load cases) was conducted with three precast panels (with rail 60 K mounted on) and compared with Finite Element Analysis results. …”

Technical Feasibility of Deceit While a Vehicle is Weighed in Motion with a Very Low Speed by Zbigniew Lozia

“…The gross vehicle mass and individual axle loads are limited by legal regulations. However, a tricking method, applicable to most popular designs of motor vehicles and multiaxial tractor-semitrailer units, has been shown that the weighing inspectors, even if provided with precise scales, may be deceived without any interference in the scale operation. …”
