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 ...

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin
Structural Concrete, EarlyView.Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.
