Study on Seismic Safety Evaluation Models for Gravity Dams Based on Integrated Performance Indicators

open access: yesRenmin Zhujiang
Existing studies typically explore the differences in seismic performance evaluation results of different evaluation models for concrete gravity dams by analyzing amplitude factors while neglecting the influence of ground motion duration.

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.

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 ...

The Newest Federalism and Population Health

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points In the United States, social policies at the federal, state, and local levels affect population health. The country is undergoing major changes in its social policies and intergovernmental relations. As both state and local governments have taken different approaches to social policies, where one resides and the socioeconomic resources ...

Syphilis and ‘Sons of Empire’: The ‘Prostitute’ and Britain's Fighting Arm in Nineteenth ̵ Century Colonial Punjab

open access: yesGender &History, EarlyView.
ABSTRACT The British army in India took great care to provide European troops with facilities for sexual relations while anxiously managing venereal disease. Examining archival evidence, political debates and medical discourse from the nineteenth century, this article examines the colonial military enterprise of regulated prostitution in colonial ...

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.
