A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Geophysical Prediction Technology Based on Organic Carbon Content in Source Rocks of the Huizhou Sag, the South China Sea

Polish Maritime Research, 2017
Due to the high exploration cost, limited number of wells for source rocks drilling and scarce test samples for the Total Organic Carbon Content (TOC) in the Huizhou sag, the TOC prediction of source rocks in this area and the assessment of resource ...

Multi-Scenario Based Assessment of Seismic Hazard: a Must for the Effective Definition of the Seismic Input

, 2013
Lessons learnt from the destructive earthquakes occurred during the new millennium provide new opportunities to take action, revise and improve the procedure for seismic hazard assessment. When dealing with cultural heritage and critical structures (e.g.

A Practical Formulation for Seismic Damage Accumulation on Multiple Mainshock‐Aftershock Sequences Based on Disaggregation of the Mainshock Hazard

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Earthquakes often occur in clusters (foreshocks, mainshocks, and aftershocks) and can lead to cumulative structural damage. Many studies have extended traditional performance‐based earthquake engineering (PBEE) to account for damage accumulation in multiple mainshock‐aftershock (MS‐AS) sequences using Markov chain processes and state‐dependent

A Reduced‐Order Model for Performance‐Based Seismic Design of Suspended Piping Systems in Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Among non‐structural elements, suspended piping systems are critical to building functionality, enabling water circulation, waste disposal and fire suppression. Their seismic damage can lead to prolonged downtime, internal flooding and substantial direct and indirect economic losses.

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...
