Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural 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 ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

open access: yesStructural 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.

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

open access: yesStructural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.
