Abstract:
In the past ten years, considerable increases in traffic volume and vehicle loads have caused obviously fatigue damage in existing highway reinforced concrete bridges in China. Some highway reinforced concrete bridges were damaged seriously, leading to the whole bridge collapse sometimes because of overloading and oversize trucks. In order to observe the highway load character in Shaanxi province, truck weigh device is set up in highway pavement to measure axle weights and axle spacing. Based on these data, it can be classified and generalized the different classes of vehicles, and drawn out the simplifying fatigue truck model in Shaanxi province. Furthermore, the fatigue truck model was used to evaluate the fatigue life and service safety of typical concrete bridges.

Abstract:
Generally, fatigue has not been considered as a key problem in the design of reinforced concrete bridges. Until the 1960s, reinforcement was mild steel and the stresses permitted in the steel bar and the concrete were such that fatigue and fracture failure was believed to be impossible. With the developments of reinforced concrete structures, higher working stresses were permitted and, in particular, high yield reinforcing bars were introduced. Design rules were issued to control cracking and to prohibit welding of reinforcement unless the risk of fatigue was negligible. In recent years, great deals of researches have been carried out, leading to a better understanding of the fatigue behaviors in concrete structures. Some studies showed that fatigue could occur in reinforced concrete structures in combination with other causes of deterioration. In the past eight years, considerable increases in traffic intensity and wheel loads have caused obviously fatigue damage in reinforced concrete structures in China. Some reinforced concrete bridges were damaged seriously, leading to the whole bridge collapse sometimes because of overloading and oversize trucks. So how to evaluate the fatigue safety of existing reinforced concrete bridges is an urgent problem in China. In the current paper, the assessment models of existing reinforced concrete bridges based on S-N curve and fracture mechanics approach were proposed considering the effect of overloading and oversize trucks. Finally the assessment method based on S-N curve and in-situ monitoring data was applied to a case study bridge.

Abstract:
Extremely heavy oversized transport is considered in the paper. Such oversized loads appears occasionally along the road network due to the restrictions of load capacity of bridges. The results of the analyses involved in the paper shows that old bridges as well as new ones are not adapted to such oversized loads. The strengthening or reconstructions of structural ele-ments are required as presented in the paper. The final remark refers to the administrative un-derstanding of the load capacity of the bridge which is based on the total weight of a vehicle. Such approach of the load capacity is not precise.

Abstract:
This paper discusses results from a series of trials carried out to determine the effect of the projectile driving band on the stress applied to a 155mm gun barrel during firing. The interference between the driving band and gun barrel can apply significant loads to the barrel and, in extreme cases, lead to premature cracking and failure of the barrel. Strain gage data from firing trials has been used to characterize the external strain from firing different projectiles and charges to identify potential problems and provide information for fatigue analysis. Very high band strains were routinely measured under “oiled bore” conditions, i.e., after barrel cleaning and also during the first one to three rounds of a serial following a long pause in firing, such as at the start of a day’s firing. In general, the strain associated with the driving band was seen to decrease with increased charge zone, barrel wear, and, at higher charge zones, distance along the barrel. In the majority of tests fired at maximum charge, there was no strain peak associated with the driving band in the forward part of the barrel. In conjunction with these experimental observations, a laboratory study has been carried out on the effect of a narrow pressure band on the deformation of a thick-walled tube. An apparatus was constructed in order to pressurize a known length of a smooth-bore cylinder. Sealing width at the edges of the band was minimized to reduce edge effects, and an oversize pressurized “cap” was used to ensure that the bandwidth remained constant during the experiments. Spacer disks were used to vary the bandwidth and also to adjust the cylinder position relative to the band. Measured external strains on the tubes were compared to calculations based on analytical solutions for step pressure changes and are shown to be in good agreement.

Abstract:
The paper sets out the results of an experiment carried out using the Virtual Battle Space 2 simulator to verify the applicability of an autonomous unmanned aerial system (UAS) reconnaissance model when moving oversized loads. The model is originally implemented within a decision-support system under military conditions. The aim of the experiment is to verify the possibilities of using the model for civilian needs. The basic output of the experiment presented in the paper is confirmation that the autonomous UAS reconnaissance model can be applied in the actual transportation of oversized loads: the experiment confirms the author’s hypothesis. Based on the result of the experiment it is possible to state that a slightly modified UAS model can significantly influence the execution phase of the oversized load movement in a positive way. It shows that the use of the model reduces the time of the movement and avoids unexpected interferences.

Abstract:
Ultrasonic machining (USM) is one of the non-conventional techniques for machining of hard and brittle materials like glass, ceramics, and ceramic matrix composites. The objective of the study includes the investigation of material removal rate (MRR), hole oversize (HOS), and circularity of holes (COH) during USM of soda lime glass and finding out the optimal parametric condition by an evolutionary algorithm. Taguchi philosophy was employed to carry out experiments using the process parameters such as power rating, abrasive slurry concentration, and static load. A novel optimization algorithm called imperialist competitive algorithm (ICA) was used to obtain maximum MRR and minimum HOS and COH. This algorithm is inspired by the imperialistic competition and has several advantages over other evolutionary algorithms like its simplicity, less computational time, and accuracy in predicting the results. The Technique for order of preference by similarity to ideal solution (TOPSIS) is utilized to convert these multiple performance characteristics to a single response. Moreover, the prediction outcomes of this TOPSIS integrated ICA methodology demonstrates excellent conformity with the experimental values and can be applied to solve complex problems.

Abstract:
Abstract Increased waterborne trade has led to the construction of ever larger ships and barges as oversized modules are transported by sea. The provision of tugs for towing such vessels has become a serious issue, especially in restricted areas often characterized by coastal regions of limited water depth. Wind loads are most relevant for towing operations because large forces act on the sail area and submerged hull of the towed vessels, such as construction barges when carrying oversized modules or fully laden containerships. Systematic steady and unsteady numerical simulations were performed using a RANS-based field method to predict wind and current forces and moments acting on representative construction barges, containerships, tankers, and passenger ships. Aero- and hydrodynamic computations were carried out separately. Aerodynamic computations considered various deck load configurations to represent realistic loading conditions; hydrodynamic computations accounted for finite water depth. Agreement with available wind tunnel experimental data was generally favorable. Our purpose was to provide a reference for wind and current loads on different barge and ship types. The objective was not to investigate flow details needed for, e.g., smoke propagation, helicopter landing, etc. This has been covered by other researchers.

<p>Currently vehicle traffic regulations regarding on axle and total weights in Korea are simple, outdated and different from the regulations in other countries, such as US or European countries. In this study, load effect of over-loaded and special permit vehicle traffic on bridges and pavements are analyzed. Types of typical bridges include concrete and steel girder bridges. Types of pavements include asphalt and cement concrete pavements. Various weigh-in-motion (WIM) truck data are collected and used for comparing overweight ratios. Based on WIM truck data, load effects of various oversize vehicles mixed with common traffic are analyzed for various bridge types. Oversize vehicles include vehicles used in construction field, crane vehicles and transport vehicles for the military purpose. The effect of axle types on pavement design is also analyzed. The results of this study will be the basis of new provisions and regulations regarding on axle and total weights limitations as well as special permit vehicle.</p>

Abstract:
To determine fuel assembly mechanical damping under PWR conditions during a postulated seismic event or LOCA, fuel assembly flowing water damping tests were needed. Since flowing water damping values are high, pluck tests were used in which the fuel assembly was deflected, pluck mechanism retracted, and fuel assembly vibration decay observed and measured. To allow for the pluck vibration to occur, an oversized flow housing was utilized, which allowed additional flow to bypass the fuel assembly in the gaps between the assembly and the flow housing walls that would otherwise flow through the bundle rodded region. Since a direct measurement of the average bundle flow velocity could not be made, a method was developed for determining the flowrate through the bundle using fuel assembly lift force measurements. This paper will present the method for determining the actual flowrate that was used in recent testing. The use of custom load cells that were designed for this testing to measure the fuel assembly lift force will be described in this paper. Additionally, the paper will show how the correlation between total test flow and bundle flow was developed from a series of flow calibration tests at different hydraulic conditions. This correlation was then used to prescribe the loop flow setpoints necessary to achieve targeted bundle flow velocities during the pluck test series.

Abstract:
We investigate taking advantage of the lightweight, compliant nature of fluidic artificial muscles to create variable recruitment actuators in the form of artificial muscle bundles. Several actuator elements at different diameter scales are packaged to act as a single actuator device. The actuator elements of the bundle can be connected to the fluidic control circuit so that different groups of actuator elements, much like individual muscle fibers, can be activated independently depending on the required force output and motion. This novel actuation concept allows us to save energy by effectively selecting the size of the actuators on the fly based on the instantaneous required load, versus the traditional method wherein actuators are sized for the maximum required load, and energy is wasted by oversized actuators most of the time. This design also allows a single bundled actuator to operate in substantially different force regimes, which could be valuable for robots that need to perform a wide variety of tasks and interact safely with humans. This paper will propose this actuator concept and show preliminary results of the design, fabrication, and experimental characterization of three such bioinspired variable recruitment actuator prototypes.

Abstract:
Swaging is one method of autofrettage, a means of pre-stressing high-pressure vessels to increase their fatigue lives and load bearing capacity. Swaging achieves the required deformation through physical interference between an oversized mandrel and the bore diameter of the tube, as it is pushed through the tube. A Finite Element model of the swaging process was developed, in ANSYS, and systematically refined, to investigate the mechanism of deformation and subsequent development of residual stresses. A parametric study was undertaken, of various properties such as mandrel slope angle, parallel section length and friction coefficient. It is observed that the axial stress plays a crucial role in the determination of the residual hoop stress and reverse yielding. The model, and results obtained from it, provides a means of understanding the swaging process and how it responds to different parameters. This understanding, coupled with future improvements to the model, potentially allows the swaging process to be refined, in terms of residual stresses development and mandrel driving force.

Abstract:
In this work, the coupled operation of a wind park and a hydrogen power-to-gas (P2G) technology is addressed in order to improve dispatchability and profitability of the wind resource. Among many available storage technologies currently under development, the P2G was chosen because of its large storage capacity and fast response. In particular, oppositely to traditional storage approaches, the solution that considers the direct injection of hydrogen in the natural gas grid infrastructure could reduce investment costs and improve the renewable fraction of fuels. Economic optimal operation and installed P2G power are calculated solving a mixed-integer linear programming (MILP) problem. Performances of the main component (electrolysis unit) are modeled, including additional costs for start-up and partial load operation losses. Technical limits on both electric and natural gas grids are also included. Some assumptions on the economic rules governing the electric grid unbalance are made, according to possible evolutions of the regulation framework focused on EU and Italian system. The simulation is performed on hourly basis, assuming realistic forecasted and real power production profiles from an actual mid-size (30 MW) wind power plant, together with prices of electricity markets and gas production. A sensitivity analysis is also performed varying both economic and technical parameters. Whereas in some scenarios the technology is profitable with the current investment costs, a reduction of electrolyzer costs down to expected mid-term targets would lead to a stronger competitiveness in each scenario. The study aims at identifying the influence of main technical and economic parameters on the effectiveness of the power-to-gas technology. Results show how the proposed solution allows better exploiting the wind resource, although the net electricity production can decrease due to the production of hydrogen, suggesting the possibility to substantially oversize the wind park in order to cover the same electric load.

Abstract:
Directed Energy Weapon (DEW) systems in a pulse operation mode dissipate excessively large, transient waste heat because of their inherent inefficiencies. The heat storage system can store such a pulsed heat load not relying on oversized systems and dissipate the stored heat over time after the pulse operation. A compressor-driven metal hydride heat storage system was developed for efficient, compact heat storage and dissipation of the transient heat from the DEW systems. The greater volumetric heat storage capacity of metal hydride material was realized into more compact design than conventional Phase Change Material (PCM) systems. Other exclusive advantages of the metal hydride system were fast thermal response time and active heat pumping capability required for precision temperature control and on-demand cooling. This paper presented the operating principle and heat storage performance results of the compressor-driven metal hydride heat storage system through system modeling and prototype testing. The modeling and test results showed that the metal hydride system can store the average heat of 4.4kW during the heat storage period of 250 seconds and release the stored heat during the subsequent regeneration period of 900 seconds.

Abstract:
Abstract The complete decommissioning of an offshore wind farm can be considered as a highly complex and hazardous approach. An unknown number of variables and unforeseen circumstances are involved in the decommissioning process. On the one hand the decommissioning of the top structure, such as blades, turbine and mast, can be handled relatively risk free by reversing the installation steps. More focus needs to be given to the recycling method and logistic. The foundation decommissioning on the other hand is a much more challenging procedure. Originally designed for high axial and lateral loads, the foundations are generally oversized concerning the loading capacity. With a diameter up to nine meter, an embedment of about 40 meter and a set up effect over 25 years, the necessary force to pull the pile out of the seabed can be assumed, if at all determinable, to be enormous. Different methods and techniques for a complete removal of offshore pile foundation are currently investigated within the project DeCoMP. Vibratory extraction and jet drilling aim for a reduction of the pile skin friction by creating a layer of less density between the pile shaft and pending soil. In a different approach the seabed is used as an abutment and a pressing force is applied by creating an overpressure inside the pile. The results of pilot test, presented in this paper, show the capability of overpressure pile decommissioning. On this basis scaled test with an extensive measurement concept will be carried out in 2020.
