Stiffness Matrices-based Formulation Of Ground Motion Synthesis And Differential Ground Motions [PDF]

, 2000
I will present the definition of the differential ground motions on free-field ground surface, and then describe numerical examples to show the characteristics of the differential ground motions as well as those of near-field ground motions.

Seismic Response of a Large-Span Steel Truss Arch Bridge under Nonuniform Near-Fault Ground Motions

Buildings
The ground motion in the near-fault region of an earthquake is characterized by exceptional energy levels, powerful velocity impulses, substantial spatial variability, and notable permanent displacement.

Directionality effects of pulse-like near field ground motions on seismic response of tall buildings

, 2015
Earthquake ground shaking at near-field sites has produced severe damage to buildings and infrastructure, caused large economic and human losses. These earthquakes continue to pose a great threat to many populous urban centers around the world.

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Study on seismic isolation performance of composite foundation based on seismic metamaterial theory under near-fault ground motion

Yantu gongcheng xuebao
Near-fault ground motions exhibit long-period velocity pulses and large-amplitude vertical components, obviously increasing structural damage. A seismic metamaterial composite foundation (SMCF) is proposed and investigated to achieve simultaneous ...

Seismic vulnerability of shallow tunnels subjected to far-field long-period ground motions

Extensive documentation and research have highlighted the destructive impact of near-field earthquakes on underground structures, while the effects of far-field earthquakes remain relatively less explored.

Shake Table Studies on Viscous Dampers in Seismic Control of a Single-Tower Cable-Stayed Bridge Model under Near-Field Ground Motions

, 2018
To investigate the effectiveness of viscous damper on seismic control of single-tower cable-stayed bridges subjected to near-field ground motions, a 1/20-scale full cable-stayed bridge model was designed, constructed and tested on shake tables. A typical

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐
