Principal axes of M-DOF structures part I: Static loadingSpringer Science and Business Media LLC - Tập 1 - Trang 293-302 - 2002
Zack Liang, George C. Lee
This paper is the first in a two-part series that discusses the principal axes of M-DOF structures subjected to static and dynamic loads. The primary purpose of this series is to understand the magnitude of the dynamic response of structures to enable better design of structures and control modification devices/systems. Under idealized design conditions, the structural responses are obtained by us...... hiện toàn bộ
A seismic free field input model for FE-SBFE coupling in time domainSpringer Science and Business Media LLC - Tập 2 - Trang 51-58 - 2003
Yan Junyi, Jin Feng, Xu Yanjie, Wang Guanglun, Zhang Chuhan
A seismic free field input formulation of the coupling procedure of the finite element (FE) and the scaled boundary finite-element (SBFE) is proposed to perform the unbounded soil-structure interaction analysis in time domain. Based on the substructure technique, seismic excitation of the soil-structure system is represented by the free-field motion of an elastic half-space. To reduce the computat...... hiện toàn bộ

Seismic response of underground utility tunnels: shaking table testing and FEM analysisSpringer Science and Business Media LLC - Tập 9 - Trang 555-567 - 2011
Luzhen Jiang, Jun Chen, Jie Li
Underground utility tunnels are widely used in urban areas throughout the world for lifeline networks due to their easy maintenance and environmental protection capabilities. However, knowledge about their seismic performance is still quite limited and seismic design procedures are not included in current design codes. This paper describes a series of shaking table tests the authors performed on a...... hiện toàn bộ
Suitable triggering algorithms for detecting strong ground motions using MEMS accelerometersSpringer Science and Business Media LLC - Tập 14 - Trang 27-35 - 2015
Ravi Sankar Jakka, Siddharth Garg
With the recent development of digital Micro Electro Mechanical System (MEMS) sensors, the cost of monitoring and detecting seismic events in real time can be greatly reduced. Ability of MEMS accelerograph to record a seismic event depends upon the efficiency of triggering algorithm, apart from the sensor’s sensitivity. There are several classic triggering algorithms developed to detect seismic ev...... hiện toàn bộ
Dynamic responses of a sediment-filled valley with a fluid layer subject to incident wavesSpringer Science and Business Media LLC - Tập 10 - Trang 175-185 - 2011
Wen-I Liao
The diffraction of elastic waves by a sedimentary valley in a homogeneous elastic half-space is studied in this paper. The sediment-filled valley is composed of a fluid layer over a soft soil deposit whose characteristics may be significant and should be carefully considered when designing long span bridges with high piers. The method of analysis adopted in the paper is to decompose the problem in...... hiện toàn bộ
Optimization of design parameters for controlled rocking steel braced dual-framesSpringer Science and Business Media LLC - Tập 21 - Trang 1053-1068 - 2022
Sobhan Ghasemi, M. Firoozi Nezamabadi, Abdolreza S. Moghadam, Mahmood Hosseini
A controlled rocking concentrically steel braced frame (CR-CSBF) is introduced as an alternative to conventional methods to prevent major structural damage during large earthquakes. It is equipped with elastic post-tensioned (PT) cables and replaceable devices or fuses to provide overturning resistance and dissipate energy, respectively. Although CR-CSBFs are not officially legalized in globally v...... hiện toàn bộ
Fully fluid-solid coupling dynamic model for seismic response of underground structures in saturated soilsSpringer Science and Business Media LLC - Tập 19 - Trang 257-268 - 2020
Li Liang, Jiao Hongyun, Du Xiuli, Shi Peixin
The seismic response characteristics of underground structures in saturated soils are investigated. A fully fluid-solid coupling dynamic model is developed and implemented into ABAQUS with a user-defined element to simulate the dynamic behavior of saturated soils. The accuracy of the model is validated using a classic example in literature. The performance of the model is verified by its applicati...... hiện toàn bộ
