Flexural behavior of precast prestressed slabs with embedded building service systems

open access: yesStructural Concrete, EarlyView.
Abstract Dry‐assembled precast concrete construction is rapidly spreading in many parts of the world due to the several advantages offered by industrialized construction. In order to speed up not only the assemblage of the structure, but also the full integrated building process, engineering systems (mechanical–electrical–plumbing) may be prefabricated

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

open access: yesStructural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

A Functional Principal Component Analysis Framework for Vibration‐Based Structural Condition Assessment of Highway Bridge Spans

open access: yesEnvironmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT The management of lifespan and safety performance, aimed at ensuring the structural integrity and durability of highway infrastructure, has become an increasingly important area of research. In civil engineering, traditional methods for evaluating dynamic behavior, such as Operational Modal Analysis and the Peak Picking technique, often fall ...

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2760-2780, September 2026.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.
