Physical and numerical modeling of seismic soil-structure interaction of prefabricated subway station structure

Engineering Structures, 2023
Physical and numerical studies were conducted to explore the seismic performance characteristics of multi-story and multi-span prefabricated subway station structures, and to identify its weak parts and damage mode during earthquakes. A two-story three-span prefabricated subway station structure was designed and fabricated with a scale ratio of 1:10 ...

Seismic Analysis of Separated Platform Subway Station Structure

Advanced Materials Research, 2010
As separated platform subway station structures are close to the bridge piles, its seismic performance need to be analyzed. An artificial earthquake record is used to analyze seismic performance of the subway station structure. The artificial earthquake record with the Kanai–Tajimi model and trigonometric series superprosition method is generated.

Seismic Response Characteristics of Subway Station Structure

Advanced Materials Research, 2013
The dynamic Davidenkov model is used to model dynamic characteristics of soils, and plastic-damage model is used to model dynamic characteristics of station structure concrete. So that, considering the influence of soil-station structure interaction for 2D finite element analysis, the dynamic interaction of soil-station structure is modeled. The damage

Monitoring and Analysis for the Deformation of SMW Retaining Structures in Subway Station

Applied Mechanics and Materials, 2014
The monitoring is carried out for deformation of the soil-mixing-wall structures used in Baijihu subway station. The horizontal displacement of deep soil is obtained, as well as the ground subsidence around the edges of the foundation pit. Their variation rules under the influence of some factors, such as soil excavation and support settings etc, is ...

Fragility analysis of a subway station structure by incremental dynamic analysis

Advances in Structural Engineering, 2016
Fragility analysis constitutes the basis in seismic risk assessment and performance-based earthquake engineering during which the probability of a structure response exceeding a certain limit state at a given seismic intensity is sought to relate seismic intensity and structural vulnerability.

Subway Station Seismic Structure Dynamic Model

Applied Mechanics and Materials, 2012
The state with tense traffic is aggravated constantly with the swift and violent development of our country economy. Surface transport is far from enough to meet the growing demand as urban traffic pressure continued growth. Therefore, subway, as a new way of transportation is developing rapidly in many great cities. Relative displacement value at both

Research on Dynamic Response of Subway Station Structure

Advanced Materials Research, 2012
Among more than three hundred cities in China, half of them are located in the earthquake zone where the seismic basic intensity is seven or even more than seven degrees, such as Beijing, Tianjin, Xi'an and other major cities which are located in the high-intensity earthquake zone of eight degrees. Since most areas of China are seismic fortified areas,
