Enhanced Seismic Retrofit of a Reinforced Concrete Building of Architectural Interest

open access: yesBuildings, 2020
Modern heritage buildings designed in the 1950s and 1960s often feature poor seismic performance capacities and may require significant retrofit interventions.

Experimental Investigation on Semi-Active Control of Base Isolation System Using Magnetorheological Dampers for Concrete Frame Structure

open access: yesApplied Sciences, 2019
The traditional passive base isolation is the most widely used method in the engineering practice for structural control, however, it has the shortcoming that the optimal control frequency band is significantly limited and narrow.

Identification of the nonlinear characteristics of rubber bearings in model-free base-isolated buildings using partial measurements of seismic responses

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2020
Rubber-bearing isolation is one of the most successfully and widely used isolation technologies to provide lateral flexibility and energy dissipation capacity for reducing structural vibration and protecting the superstructure from damage.

Observed Seismic Behavior of a HDRB and SD Isolation System under Far Fault Earthquakes

open access: yesInfrastructures, 2022
The behavior of a reinforced concrete building, seismically isolated with high damping rubber bearing (HDRB) and sliding devices (SD), observed during the most important events of the seismic sequence that struck central Italy from August 2016 to January

Evolution and molecular bases of reproductive isolation

open access: yesCurrent Opinion in Genetics & Development, 2022
The most challenging problem in speciation research is disentangling the relative strength and order in which different reproductive barriers evolve. Here, we review recent developments in the study of reproductive isolation in yeasts. With over a thousand genome-sequenced isolates readily available for testing the viability, sterility, and fitness of ...

SEISMIC MONITORING OF BUILDING WITH BASE ISOLATION

open access: yesProceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
The seismic monitoring of buildings is important for two fundamental reasons: - evaluate the possible dynamic behavior of these structures during earthquakes; - gain experience on the general seismic behavior of the structures so that the experience and the database can be used in the future for design and analysis.

Cluster-Based Improved Isolation Forest

open access: yesEntropy, 2022
Outlier detection is an important research direction in the field of data mining. Aiming at the problem of unstable detection results and low efficiency caused by randomly dividing features of the data set in the Isolation Forest algorithm in outlier detection, an algorithm CIIF (Cluster-based Improved Isolation Forest) that combines clustering and ...

3D BASE ISOLATION OF BUILDINGS

open access: yesProceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
A 3-D base isolation system to control the structural effects of both the horizontal and vertical components of ground motion has been recently presented in literature and it is herein briefly summarized. A building model is used to test the 3D base isolation arrangement that consists of elastomeric bearings acting both in the horizontal and vertical ...
