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 ...

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 This paper presents an analytical model to predict the shear strength of RC beams affected by corrosion within the Level IIb framework of fib Model Code 2020. Corrosion is accounted for by (i) reducing the area of longitudinal reinforcement, (ii) degrading the yield strength of stirrups according to Imperatore's law, and (iii) reducing the ...

MATEC Web of Conferences, 2013 Small and large scale reinforced concrete panels/walls were tested under hydrocarbon fire conditions to investigate concrete spalling. Results indicated that spalling is caused by the combination of thermal stresses and pore water pressure build-up.

Large-bore tapered-roller bearing performance and endurance to 2.4 million DN [PDF]
, 1983 The operating characteristics and experimental life estimates for 120.65 mm bore tapered roller bearings of two designs under combined radial and thrust loads were determined. A modified standard bearing design was tested at speeds up to 15,000 rpm.

Structural Concrete, EarlyView.Abstract The use of steel fiber‐reinforced concrete (SFRC) has seen a significant rise in the construction industry due to advancements in material science, improved quality, and cost efficiency. Similarly, the importance of fastening systems in construction has grown, necessitating robust research on the performance of fasteners in SFRC to ensure safe

Oxidation behavior of FeAl+Hf,Zr,B [PDF]
The oxidation behavior of Fe-40Al-1Hf, Fe-40Al-1Hf-0.4B, and Fe-40Al-0.1Zr-0.4B (at. percent) alloys was characterized after 900, 1000, and 100 C exposures.

The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]
, 2000 Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the
