Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

open access: yesStructural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

open access: yesStructural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Serviceability reserves of historic reinforced concrete slabs implications for structural reuse

open access: yesStructural Concrete, EarlyView.
Abstract The transition to a circular economy in the construction sector requires reliable methods to assess whether existing reinforced concrete elements can be reused in new load‐bearing structures. A central question is whether slabs designed according to historical standards also meet today's serviceability requirements.

Defining Lines of Defense Against Change Propagation Using Cause‐Consequence Analysis

open access: yesSystems Engineering, EarlyView.
ABSTRACT Complex engineered systems are the core of modern society. So that engineered systems and infrastructure can be sustainable and offer value over the course of their lifespan, there is a growing need for such systems to be changeable. Yet, establishing and operationalizing changeability can be challenging due to the potential for change ...
