Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

Structural Concrete, EarlyView.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

CORR‐DATA: A database of corrosion parameters measured on existing reinforced concrete structures for enhanced structural assessment

Structural Concrete, EarlyView.
Abstract The corrosion of reinforcing bars embedded in concrete strongly compromises structural performance over time. However, its detection and quantification remain challenging due to limited comprehensive knowledge of natural corrosion patterns in existing structures.

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, EarlyView.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Performance of two‐to‐one non‐contact post‐installed lap splices

Structural Concrete, EarlyView.
Abstract Post‐installed lap splices ensure the continuity of steel reinforcement in concrete‐to‐concrete connections by overlapping cast‐in (CI) reinforcing bars (rebars) with post‐installed (PI) rebars. Typically, the design of such splices follows provisions originally intended for CI lap splices, despite the differences in execution and bond ...

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

Structural Concrete, EarlyView.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Defocused illumination with beam‐shaping condenser for uniform wide‐field X‐ray imaging

Journal of Synchrotron Radiation, EarlyView.
A defocused illumination method based on a beam‐shaping condenser to suppress fringe artifacts arising from rectangular aperture diffraction and sub‐grating interference is developed, providing an effective and practical approach for achieving wide‐field and uniform illumination in X‐ray microscopy.The beam‐shaping condenser (BSC) has become a key ...
