Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

open access: yesStructural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

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

open access: yesStructural 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.

Mechanics‐based model for cold joints in reinforced concrete members

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Explainable artificial intelligence (XAI)‐powered design framework for lightweight strain‐hardening ultra‐high‐performance composites (SH‐UHPC)

open access: yesStructural Concrete, EarlyView.
Abstract Lightweight strain‐hardening ultra‐high‐performance concrete composite (SH‐UHPC) is an outstanding alternative for engineering applications and infrastructure thanks to its outstanding strength, toughness, ductility, and low density. The integration of artificial intelligence (AI)‐based modeling strategies into engineering problems can ...

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

open access: yesStructural Concrete, EarlyView.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...
