Nonlinear Response and Collapse Analysis of Double-Channel Aqueduct under Strong Earthquake

Advances in Civil Engineering, 2022
As a common water conveyance structure, aqueduct is widely used in cross-regional water conveyance and diversion projects. However, large double-trough aqueduct structures are prone to damage under earthquake, resulting in water leakage and even ...

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer

Aging and Cancer, EarlyView.
Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.

Enhanced Earthquake Performance of Existing RC Buildings Through Hybrid CFRP and Damper Retrofitting

Buildings
Interest in applying hybrid retrofitting approaches to existing buildings is steadily increasing. In this study, an attempt was made to seismically retrofit an RC (reinforced concrete) building using CFRP (carbon fiber-reinforced polymer) and dampers ...

The effect of moment redistribution on the stability of reinforced concrete moment resisting frame buildings under the ground motion [PDF]

Journal of Structural and Construction Engineering, 2017
In recent years some studies have been done on the moment rredistribution in buildings and new methods offered for calculating of redistribution. Observations demonstrated that the combination of moment and shear force is important in analysis of ...

An Efficient Computational Strategy for Nonlinear Time History Analysis of Seismically Base-Isolated Structures

, 2020
Nonlinear time history analysis represents the most appropriate structural analysis procedure to accurately analyze seismically base-isolated structures since their dynamic response is typically governed by a system of coupled nonlinear ordinary differential equations of the second order in time.

Development of seismic fragility surfaces for reinforced concrete buildings by means of nonlinear time‐history analysis [PDF]

Earthquake Engineering & Structural Dynamics, 2009
AbstractFragility curves are generally developed using a single parameter to relate the level of shaking to the expected structural damage. The main goal of this work is to use several parameters to characterize the earthquake ground motion. The fragility curves will, therefore, become surfaces when the ground motion is represented by two parameters ...

Extended Rayleigh Damping Model

Frontiers in Built Environment, 2016
In dynamic analysis, frequency domain analysis can be used if the entire structure is linear. However, time history analysis is generally used if nonlinear elements are present.

Clinical and Modifiable Factors Associated With Disability and Relapse in MOGAD: A Multicentre Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Factors associated with relapse course and disability in myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) remain incompletely understood. Objectives To identify clinical and modifiable factors associated with relapse and disability in MOGAD. Methods In this ambispective multicentre cohort study using data from

The Assessment and Comparison of Tall Buildings with Outrigger and Belt Truss Systems Using Fragility Curves [PDF]

Journal of Structural and Construction Engineering, 2018
In the design of high-rise buildings, three parameters such as resistance, hardness and stability are very important and when the height of building rises, effect of toughness and stability in optimum design will be dominate more than of the effects of ...
