Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

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

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.

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

Structural 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 ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Behaviour of reinforced recycled concrete aggregate beam with addition of steel fiber and kenaf fiber (hybrid) [PDF]

, 2017
The use of recycled concrete aggregate (RCA) in concrete mixture as partial replacements of natural coarse aggregate is growing interest in the construction industry. Concrete recycling gains importance because it protects natural resources.
