Flexural Behavior of a 30-Meter Full-Scale Simply Supported Prestressed Concrete Box Girder

open access: yesApplied Sciences, 2020
Compared with scaled-model testing, full-scale destructive testing is more reliable since the test has no size effect and can truly record the mechanical performance of the structure.

Confronting the caliphate? Explaining civil resistance in jihadist proto-states

open access: yesEuropean Journal of International Relations, 2020
Research has shown the potential of nonviolent civil resistance in challenging autocratic state regimes (e.g. Sharp, 1973; Chenoweth and Stephan, 2011). Yet, little is known about its applicability in jihadist proto-states, that is, territories governed ...

Feasibility analysis of treating aeolian sand and recycled mixed powder as environmentally friendly materials in the ultra-high-performance concrete

open access: yesDevelopments in the Built Environment, 2023
This paper addresses the performance and environmental impact evaluation of a developed UHPC with recycled mixed powder (RMP) and aeolian sand (AS). The RMP is obtained from the crushing and grinding of waste concrete blocks and clay bricks.
