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.

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

open access: yesStructural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

Vibration-based damage detection in an aircraft wing scaled model using principal component analysis and pattern recognition [PDF]

open access: yes, 2008
This study deals with vibration-based fault detection in structures and suggests a viable methodology based on principal component analysis (PCA) and a simple pattern recognition (PR) method. The frequency response functions (FRFs) of the healthy and the

Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

open access: yesStructural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...

An approach for seismic damage assessment of residential buildings

open access: yes, 2020
For developing countries in earthquake-prone regions, two main issues in seismic damage estimation are identification of seismic hazard in the region of interest and up-to-date information of the existing building stock. This study proposes an approach to handle these key issues and to obtain reliable measures for regional seismic damage estimation ...

Multi-Scenario Based Assessment of Seismic Hazard: a Must for the Effective Definition of the Seismic Input

open access: yes, 2013
Lessons learnt from the destructive earthquakes occurred during the new millennium provide new opportunities to take action, revise and improve the procedure for seismic hazard assessment. When dealing with cultural heritage and critical structures (e.g.

The use of continuum models for analyzing adobe structures [PDF]

open access: yes, 2012
As it is known, the adobe structures have a high seismic vulnerability principally due to the low material strength and sometimes due to the inadequate structural configuration.

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape

open access: yesAnimal Conservation, EarlyView.
Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

open access: yesAnimal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.

Significant Far‐Right Challenges to Australian Society? The XYZ and AustraliaOne

open access: yesAustralian Journal of Politics &History, EarlyView.
ABSTRACT Scholars who analyse the Australian far‐right from a criminological or security studies perspective propose that activists and groups pose ‘political’ challenges to Australian society. This paper examines the far‐right news website The XYZ and the AustraliaOne political party, and argues that claims that the far‐right may normalise ...
