Abstract:
With long-term operation of high-speed railways, bridge deformation is hard to avoid, which directly affects the mechanical property of longitudinal connected track. To ensure the structural stability of longitudinal connected track and operation safety of train, this work proposes a work to evaluate longitudinal connected track under combined action of running train and long-term bridge deformation. First, the methodology of evaluating longitudinal connected track subject to train load and long-term bridge deformation has been proposed, in which an accurate train–track–bridge dynamic model an

Abstract:
The deformation mechanism of unit cell wall is investigated by use of FEM, and the numerical simulation results show that the predominant deformations consist of shear deformation and compressive deformation. One new model based the shear deformation and the compressive deformation is put forward to investigate the longitudinal shear modulus of honeycomb cores. Owing to taking skin effect into consideration in our model, it is found that the equivalent shear modulus depends on not only the material properties and configuration parameters of cores, but also the material properties and configura

Adjacent tunnel construction and environmental disturbances can lead to longitudinal deformation in pipe-jacking tunnels. The longitudinal deformation of the tunnel is closely related to the occurrence of joint dislocation, joint opening, and other defects.

Background: Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV).

Thus, lifelong follow-up of these patients is required. Echocardiography is the most patient’s friendly method to evaluate CoA and in particular its effect on LV function.

Abstract:
Continuous buried pipelines are generally required to traverse long distances and as such, inevitably pass through unstable landforms which may impart critical levels of stress beyond the intrinsic capacity of the pipelines. The deformational response of buried pipelines subject to relative ground movement is strongly influenced by the geotechnical properties of the immediate backfill and surrounding soil, the size and direction of the soil movement in which the pipeline is embedded, as well as mechanical soil-pipe interaction behavior. With respect to the mode of deformation, relative ground

Abstract:
This report provides an overview and introduction to the use of strain-based design and assessment (SBDA) approaches to ensure mechanical integrity for pipelines that may be (design focus) or have been (operational focus) subjected to significant ground deformation. Appropriately designed pipelines subjected to significant ground deformation can accommodate longitudinal bending loads that induce tension and/or compression loads well beyond yield without impacting pressure containment. Strain-based procedures for evaluating and ensuring pipeline integrity for such potential pipeline hazards are

Abstract:
This report describes the design, construction, and shaking table response and computation simulation of a Low Seismic-Damage Bridge Bent built using Accelerated Bridge Construction methods. The proposed bent combines precast post-tensioned columns with precast foundation and bent cap to simplify off- and on-site construction burdens and minimize earthquake-induced damage and associated repair costs. Each column consists of reinforced concrete cast inside a cylindrical steel shell, which acts as the formwork, and the confining and shear reinforcement. The column steel shell is engineered to fa

Abstract:
Earthquakes, which can cause tremendous local stress and strain on infrastructure, can cause reinforced concrete (RC) bridges to collapse due to the concrete cracking and fracture of the steel reinforcement rebars. The fracture of longitudinal reinforcing steel due to low-cycle fatigue is one of the main causes of failure in RC structures under earthquake loading. The purpose of this research is to include the effects of low-cycle fatigue fracture of longitudinal reinforcing steel bars on the seismic performance of reinforced concrete bridge piers. To obtain a greater understanding of low-cycl

Abstract:
Some of the future pipelines are expected to be constructed in remote areas. The environment in these areas can impose higher longitudinal plastic deformation on the pipelines. Such environmental conditions include, but not limited to, frost heave and thaw settlement in the northern arctic region, seismic activity, slope instability, mine subsidence, upheaval buckling, etc. The overall industry experience for this type of loading is very limited. The other trend in new pipeline construction is the move towards higher internal pressure (design factor of 0.80 as opposed to the more traditional 0

Comparison of mechanical behavior between longitudinal lap-welded joints and transverse fillet welded joints of high strength steel. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/icass2020.p.302.

Abstract:
Mechanical behavior of twenty-eight longitudinal lap-welded joints made of high strength steels (HSS) under tension load was investigated by experimental study. Weaknesses due to traditional deformation measurements for fillet welded joints can be perfectly solved by digital image correlation techniques (DIC). The effect of parameters (e.g. weld size, weld length and mismatch ratio) on mechanical properties (e.g. ultimate strength, failure modes, weld ductility and fracture angle) of longitudinal fillet welds and transverse fillet welds, which was introduced in detail in previous work by the a

Abstract:
"The development of wind power technology requires higher and larger wind turbines, which requires the bearing tower to increase its height and diameter. The assembled internal stiffened wind turbine tower divides the tower into multiple arc plates along the longitudinal direction, which can be easy transported to the site for assembly. That can solve the problem of height limit in highway transportation. At the same time, the internal stiffener provides better stability and can replace the bottom tower section of conventional wind turbine tower. In this study, the tower section of assembled i
