Experimental Study on the Seismic Behavior of CFST Self-Centering Rocking Bridge Piers
Compared to conventional reinforced concrete (RC) piers, self-centering rocking piers exhibit better seismic resilience and sustain minor damage. However, their construction typically relies on prefabrication.

ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

SEISMIC BEHAVIOR OF INTAKE TOWER OF DAM
Intake towers are typically tall, hollow, reinforce d concrete structures and form entrance to reservoi r outlet works. A parametric study on dynamic behavior of circular cylindrical t owers can be carried out to study the effect of dep th of submergence, wall thickness and slenderness ratio, and also effect on tower con sidering dynamic analysis for ...

ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?
ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Investigation of the Seismic Behavior of Masonry Structure
Seismic performance is considered one of the most important issues in ensuring stability and safety for buildings sited in earthquake-prone countries. This research covers seismic behavior in shake table testing of masonry structures. Most of the research focuses on the dynamic response of masonry configurations under various simulated seismic loads ...
