Constant Ductility Energy Factors for the Near-Fault Pulse-Like Ground Motions

Journal of Earthquake Engineering, 2016
This study is focused on the constant ductility energy factors for bilinear system under the near-fault pulse-like ground motions. The variation of energy factors is studied in consideration of the earthquake magnitude, rupture distance, damping ratios, and post-yield stiffness ratios.

A comprehensive categorization method for identifying near‐fault pulse‐like ground motions

Earthquake Engineering & Structural Dynamics
AbstractIdentifying near‐fault pulse‐like ground motions from extensive ground motion databases holds paramount importance, as it provides a pivotal foundation for further inquiries into this specific type of ground motions, including the modeling of such stochastic processes as well as thorough analysis of their potential impact on structures and ...

Nonlinear dynamic response of a tall building to near-fault pulse-like ground motions

Bulletin of Earthquake Engineering, 2019
The objective of this study is to determine the effects of near-fault ground motions with large, medium and small pulse periods on a core-wall tall building. Three near-fault and one far-field ground motion sets, each with 11 different records, are rotated to the maximum pseudo-velocity spectrum directions.

Pulse-Like Near-Fault Ground Motion Effects on the Ductility Requirement of Bridge Bents

TCLEE 2009, 2009
This paper discusses the ductility requirement for a typical bridge pier or bent subjected to extreme loads such as those from pulse-like near-fault ground motions. The ductility requirement as stated by prevailing design codes may not be valid for such structures in near-fault (less than 10 miles) zones.

Effects of Near-Fault Pulse-Like Ground Motion on Site Liquefaction and Settlement

2018
A soil column of 20 m is established to simulate the seismic responses of free site by using the open source finite element software OpenSees. The characteristics of site liquefaction are investigated under near-fault ground motions, especially under the ground motion component with directivity effect. Based on the index of unit settlement of site, the

Incorporation of near-fault pulse-like ground motions into performance-based design

The performance-based design methodology requires accurately estimating the structural demands. For this reason, the relationship between the structural demands and the characteristics of the ground motions has been an attractive topic in earthquake engineering.

Fragility analysis of tall pier bridges subjected to near-fault pulse-like ground motions

Structure and Infrastructure Engineering, 2019
More than 40% of bridges in Southwest China have piers over 40 m height. The seismic behaviour of these bridges is critical, especially exposed to near-fault pulse-like ground motions.

Near-fault directivity pulse-like ground motion effect on high-speed railway bridge

Journal of Central South University, 2014
The vehicle-track-bridge (VTB) element was used to investigate how a high-speed railway bridge reacted when it was subjected to near-fault directivity pulse-like ground motions. Based on the PEER NAG Strong Ground Motion Database, the spatial analysis model of a vehicle-bridge system was developed, the VTB element was derived to simulate the ...
