Structural health monitoring (SHM) provides a useful tool for ensuring safety and detecting the evolution of damage and performance deterioration of civil infrastructures. A great number of civil infrastructures under construction can be used as test beds for SHM systems. The Binzhou Yellow River Highway Bridge is a cable-stayed bridge in Shandong Province, China. An SHM system has been impleme...

To scientifically characterize the dynamic mechanical characteristics of rubber pad under rail fasteners and its influence on response vehicle-rail-viaduct system, taking WJ-7B high-speed railway (HSR) with constant resistance as an example, a TFDV model was applied to viscoelasticity theoretical in coupling vehicle-rail-bridge also studied. The results show that energy storage modulus loss fac...

This paper describes an approach based on reachability calculations for ensuring robust operation guarantees in flight maneuver sequences performed by unmanned aerial vehicles (UAVs) under supervision of human operators, with applications to safety-critical scenarios. Using a hybrid system formalism to model the maneuver sequence, the paper devises systematic procedures for designing switching ...

This study was carried out to determine the strength of long span stone bridges and stress areas a historical bridge by using finite element method during earthquakes, floods, vehicle traffic. The possible earthquake impact region behavior under effect 2011 Van were investigated. stresses that will be caused hydrostatic loading applied are dwelled on. aimed shed light on future restoration work...

Abstract: Fatigue fracture of bridge stay-cables is usually a multiscale process as the crack grows from micro-scale to macro-scale. Such a process, however, is highly uncertain. In order to make a rational prediction of the residual life of bridge cables, a probabilistic fatigue approach is proposed, based on a comprehensive vehicle load model, finite element analysis and multiscaling and meso...

Mathematical modeling of supply chain operations has proven to be one of the most complex tasks in the field of operations management and operations research. Despite the abundance of several modeling proposals in the literature; for vast majority of them, no effective universal application is conceived. This issue renders the proposed mathematical models inapplicable due largely to the fact th...

The advent of depth cameras has enabled mid-air interactions for shape modeling with bare hands. Typically, these interactions employ a finite set of pre-defined hand gestures to allow users to specify modeling operations in virtual space. However, human interactions in real world shaping processes (such as pottery or sculpting) are complex, iterative, and continuous. In this paper, we show tha...

The track–bridge interaction is a fundamental concern in the field of railway engineering, which plays an important role optimization design bridges, especially for heavy-haul and high-speed bridges. This paper systematically introduces research status CWR large-span bridges China. evolution process model from simplest elastic bar linear longitudinal resistance to complex beam–rail considering ...
