External Vibrations on Early‐Age Concrete: A Review
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...

This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

Mechanical Properties and Fracture Surface Morphology of Quartz Sandstone Under Triaxial Shear
To study the shear damage deformation characteristics of intact rock in rock slopes under three-dimensional compressive–shear stress conditions, 16 sets of triaxial shear tests were conducted on saturated intact fine-grained quartz sandstone with simple ...
