Monitoring of historical structural materials with computed tomography
Structural Concrete, EarlyView.Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Structural Concrete, EarlyView.Abstract Our generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of ...

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 ...

Corrosion induced cracking modelled by a coupled transport-structural approach [PDF]
, 2017 Transport of corrosion products into pores and cracks in concrete must be considered when predicting corrosion induced cracking in reinforced concrete structures, since this transport significantly delays the onset of cracking and spalling by reducing ...

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 ...

Epoxy-Induced Spalling of Silicon
Energy Procedia, 2012 AbstractOne of the main driving forces to lower the silicon solar cell modules overall cost is to decrease the thickness of the silicon substrate and, at same time, to reduce the material losses caused by the sawing of the silicon ingot. For this reason, a considerable number of methods have been proposed in the last decade to manufacture thin silicon ...

Structural Concrete, EarlyView.Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...

Structural Concrete, EarlyView.Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...
