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

Bond‐slip modeling for reinforced concrete beam‐column joints with plain reinforcement bars: Insights from numerical validation

Structural Concrete, EarlyView.
Abstract The previous seismic events indicated the vulnerability of old reinforced concrete (RC) structures against earthquakes due to the absence of seismic detailing and capacity design specifications in such buildings. In this context, beam‐column joints (BCJ) of the existing RC structures built before the 1970s have exhibited poor structural ...

Assessment of the factor κk,max in classification of steel fiber‐reinforced concrete

Structural Concrete, EarlyView.
Abstract This paper presents a general approach, and results employed in a study aimed at assessing the value of a coefficient, κk,max, introduced in Annex L in EN 1992‐1‐1:2023 (EC2). This coefficient defines an upper limit of the ratio between steel fiber reinforced concrete (SFRC) characteristic and mean values of the residual tensile strengths, fR1

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 ...
