Investigation of Hybrid Simulation With Model Updating Compared to an Experimental Shake Table Test

open access: yesFrontiers in Built Environment, 2020
In hybrid simulation, response time history measured from an experimental substructure can be utilized to identify the model associated with the tested specimen in real time.

地震动作用下刚体扭转效应的振动台模拟试验

open access: yesDizhen xuebao, 2022
2008年汶川地震中江油市太白公园曲径桥上的石雕发生转动破坏现象,本文对这一转动现象进行了振动台模拟试验。模拟试验结果表明:① 在振动台三向加载1.5倍的汶川地震江油台记录的平动加速度后,模型的转动情况与实际观测的石雕转动情况比较一致;② 石雕的转动与石雕的非对称性、地震动输入角度和地震动的竖向作用有关;③ 加载竖向地震动作用后,石雕模型会发生摇摆现象,说明竖向地震动是造成模型扭转现象的重要原因,这也说明在分析相似震害现象时竖向地震动作用不可忽视。

Modeling of electron emission processes accompanying Radon-$\alpha$-decays within electrostatic spectrometers [PDF]

open access: yes, 2013
Electrostatic spectrometers utilized in high-resolution beta-spectroscopy studies such as in the Karlsruhe Tritium Neutrino (KATRIN) experiment have to operate with a background level of less than 10^(-2) counts per second.

An Analytical Solution for Block Toppling Failure of Rock Slopes during an Earthquake

open access: yesApplied Sciences, 2017
Toppling failure is one of the most common failure types in the field. It always occurs in rock masses containing a group of dominant discontinuities dipping into the slope.

Effect of earthquake excitation on circular tunnels: Numerical and experimental study

open access: yesMeasurement + Control, 2019
This paper studies the behaviour of circular tunnel subjected to dynamic excitation. Tunnels with three different diameters were selected to perform the shake table test at three different covers. The dry sandy soil was used for testing.

Two-electron processes in multiple ionization under strong soft-x-ray radiation [PDF]

open access: yes, 2016
In a combined experimental and theoretical study we have investigated the ionization of atomic argon upon irradiation with intense soft-x-ray pulses of 105 eV photon energy from the free-electron laser FLASH. The measured ion yields show charge states up
