Damage and failure of underground subway stations under different soil constraint conditions

open access: yesPLOS ONE, 2023
Investigations from past earthquakes have shown that underground subway stations can suffer excessive deformation under strong seismic loads, leading to the damage of critical components and the collapse of structures. This study presents the results of finite element analyses on the seismic damage of underground subway stations installed under ...

Building Evacuate Module for Urban Underground Passages: Subway Station in Turkey

open access: yesJournal of Transportation Technologies, 2015
The primary goal of crowd evacuation in urban underground passages or subways is to evacuate as many evacuees as possible to safe areas in the shortest time when emergency events occur. This paper chooses the underground passages of one metro in Istanbul, Turkey as research object, and uses a study method which combines by sites investigation, field ...
