Advances in Civil EngineeringTo investigate the collapse mechanisms of diversion tunnels during construction under seismic loading, a coupled continuum-discrete numerical simulation method was employed. Before seismic excitation, the initial support system was generally stable, with

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 ...

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 ...

Full-Scale Pseudo-Dynamic Test for Bridge Retrofitted With Seismic Isolations
The Baltic Journal of Road and Bridge Engineering, 2008 This paper presents the performance of a retrofitted bridge with a seismic isolation. To validate the seismic performance of retrofitted bridge experimentally, four full-scale reinforced concrete bridge piers with fixed support conditions were fabricated

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 ...

Structural Concrete, EarlyView.Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Structural Concrete, EarlyView.Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
