Journal of Periodontology, EarlyView.Abstract Background The aim of this study is to evaluate the impact of different implant materials and arrangements within the field of view (FOV) and exomass on the diagnostic accuracy and image quality of cone‐beam computed tomography (CBCT) for the detection of peri‐implant buccal bone defects of various sizes. Methods A total of 120 CBCT scans with

Predicting scour at river bridge abutments over time [PDF]
, 2015 Good prediction of scour depth over time is essential for the design of river bridge foundations. In this study, two empirical models are developed to predict the temporal variation of local scour at uniform-section bridge abutments and those with ...

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Numerical Modeling of Local Scour in the Vicinity of Bridge Abutments When Covered with Ice
, 2023 The occurrence of bridge collapse is frequently attributed to the prevalent erosion in the vicinity of bridge abutments. Accurate determination of the maximum scour depth in the vicinity of bridge abutments is imperative to ensure a secure and reliable ...

Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Early use of the reinforced concrete in the architecture of the Historicism in Austria–Hungary
Structural Concrete, EarlyView.Abstract The study examines the early incorporation of reinforced concrete in the architecture of Historicism in Austria–Hungary. Spanning the late 19th to early 20th centuries, the research illuminates the period's stylistic pluralism and the transformative impact of reinforced concrete.

Local Scour at Bridge Abutments
Journal of King Abdulaziz University-Engineering Sciences, 1998 This paper presents the results of an experilnental investigation of local scour at bridge abutment models of three common shapes placed in laboratory flume with uniform sand with d)l) =0.775 mm. The 1l1uximum scour depths and extent of scour were determined corresponding to clear water conditions.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study
Structural Concrete, EarlyView.Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
