Impact of Beam‐Column Joint Modeling Uncertainties on the Seismic Response of Low‐Rise RC Frames

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Incremental recordwise Latin hypercube sampling (iLHS) and multiple stripe analysis (MSA) are employed to evaluate the seismic performance of low‐rise RC moment‐resisting frames subjected to uncertainties of both the values of the model parameters and the model type itself.

Optimization of Viscoelastic Tuned Mass Damper Systems Subjected to Coloured Excitations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In recent decades, there has been growing interest in innovative vibration control strategies to improve the structural reliability of buildings and civil structures against earthquakes, windstorms and other dynamic excitations. One of the most effective methods for reducing dynamic responses is the implementation of tuned mass dampers (TMDs),

Verification of High‐Performance Force Measurement Method for E‐Isolation Based on Dynamics of Testing Facility

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A thorough understanding of the dynamics of the seismic isolators is essential for evaluating the seismic response of seismically isolated structures. However, the loading tests of full‐scale seismic isolators are limited because of the capacity of the testing facilities. Consequently, a new full‐scale testing facility—E‐Isolation—was built in

Seismic Fragility Assessment of a Multi‐Span Masonry Arch Bridge Using a Discontinuum Modeling Approach

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper investigates the seismic performance of a multi‐span masonry arch bridge using an advanced modeling approach based on the Distinct Element Method. Located in Italy and constructed of regular stone masonry, the bridge features three consecutive arch vaults with similar geometry.

Seismic Retrofit of Non‐Seismically Designed 3D Beam‐Column Joints With Post‐Installed Steel Haunches

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The paper presents experimental results on two‐dimensional and three‐dimensional full‐scale exterior reinforced concrete beam‐column joints subassemblies retrofitted with the Fully Fastened Haunch Retrofit Solution. The specimens were non‐seismically designed with no transverse reinforcement in the joint core, thus making them vulnerable to ...

NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]

, 2010
The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...

Quantitative Evaluation of Sand Body Connectivity Based on the Support Vector Machine Algorithm: A Case Study of the Putaohua Oil Reservoir in the Daqing Oil Field, Songliao Basin, China

Energy Science &Engineering, EarlyView.
A support vector machine (SVM) algorithm was applied to quantitatively predict the connectivity of the sand bodies. Verification using dynamic and static data demonstrated that the prediction accuracy of the algorithm reached 88%. The quantitative sand body connectivity results were used to establish a single sand body model.

Carbon Storage in Fold‐and‐Thrust Belts: An Overlooked Gigatonne Storage Opportunity

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT This study presents numerical investigations of the trapping characteristics of fold‐and‐thrust belt structures, defining three carbon capture and storage (CCS) play types that could be used to store commercial volumes (millions of tonnes) of CO2.
