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

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

Simulation of seismic response in a city-like environment

, 2004
We study the seismic response of idealized 2D cities, constituted by non equally-spaced, non equally-sized homogenized blocks anchored in a soft layer overlying a hard half space. The blocks and soft layer are occupied by dissipative media.

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 ...

Innovative development and structural behavior of hollow columns using inflatable molds

Structural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

The feasibility of separating the pipe rack from the foundation to reduce the effects of earthquakes [PDF]

مهندسی و مدیریت ساخت
One of the most important structures are pipe racks, which are usually made from concrete, steel, or a combination of the two materials that are used to maintain pipes and other equipment at the required levels.
