Seismic vulnerability of deep tunnels influenced by chloride ion corrosion

open access: yesShenzhen Daxue xuebao. Ligong ban
Chloride ion erosion adversely affects the seismic performance of tunnels, making it essential to study the seismic vulnerability of tunnels in corrosive environments for a comprehensive seismic assessment over their entire lifecycle.

Definition of seismic and tsunami hazard scenarios by exploiting EU-India Grid e-infrastructures [PDF]

open access: yes, 2012
Seismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude.

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Seismic Performance of Irregular Buildings

open access: yesIndian Journal of Science and Technology, 2014
Modern building planning is influenced by many factors and often, there is a trend to adopt a form that has irregular shape in plan and also has variation in height of storeys. Due to the varied use, a building is planned for; variations in the load acting on different floors may also differ.

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Directionality Scaling of Scalar and Vector Ground Motion Intensity Measures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The azimuthal directionality of earthquake ground‐motion intensity measures (IMs) is conventionally described by the ratios between the orientation‐independent maximum (RotD100) and median (RotD50) values over the horizontal plane. This study presents a refined characterization of the directionality of 31 IMs, including spectral accelerations (

Seismic Performance of Masonry Building

open access: yes, 2012
The frequent occurrence of huge earthquake in the recent years results catastrophic losses to the people’s life and property, which is mainly caused by the devastation of many buildings. The Tangshan Earthquake (Ms 7.8,1976) and Wenchuan Earthquake (Ms 8.0,2008) should be mentioned here for the destructive influence on the development of China in the ...

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...
