Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

Design and analysis of a three-dimensional seismic isolation device for small modular reactor building

Nuclear Engineering and Technology
Seismic isolation in nuclear power plant (NPP) buildings has been infrequently applied using a rubber-based horizontal seismic isolation system (SIS) without vertical isolation under a peak ground acceleration (PGA) of 0.3 g as the seismic design ...

Evaluation of Seismic Performance for Bridges Isolated with Lead-Rubber Seismic Isolator Bearing

Journal of Applied Environmental and Biological Sciences, 2015
Lead rubber bearing (LRB) is the most developed and the most common seismic isolator in the world that can reduce 60- 80 percent of the seismic force to structures. Isolators are applied in bridge design to achieve maximum energy absorption (relative to the period in isolated buildings). Therefore, isolators with high damping should be used.

Seismic Isolation Using Slide and Rubber Bearings: Large Amplitude Free Vibration Tests on "Rapolla Residence Building"

, 2001
An application of a mixed seismic isolation system (slide bearings for isolation and steel rubber bearings to have a recentering force) is presented. Such technique has been applied to a residence building, built in Italy at Rapolla (PZ- Basilicata). The

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.
