MS Title:
Seismic Fragility Analysis and Performance Assessment of Underground Infrastructure under Uncertainties
 

Description:
Underground infrastructure plays a pivotal role in urban lifeline infrastructure systems in maintaining the daily operation, emergency response and post-disaster rescue and restoration of modern cities. The performance of underground infrastructure subjected to strong earthquakes have been attract much attention in the earthquake engineering community over last decades. Given the complex nonlinear interactions between the surrounding soil and the underground structures, the tasks of seismic fragility analysis and performance assessment of underground infrastructure still remains challenging to explicit consider many uncertainties associated with the earthquake ground motions, soil properties, structural materials and systems. In recent years, with the developed machine learning technology, many advanced and computationally efficient methodologies have been developed to address and quantify the influences of different sources of uncertainties to the seismic performance of underground infrastructure considering nonlinear dynamic soil-structure interaction. In view of this situation, the aim of this mini-symposium is addressing the advances on theories and methods of seismic performance assessment of underground infrastructures considering the uncertainties such as ground motions, soil properties, structural materials, etc. The scope of the mini-symposium is broad, pertinent research and contributions that are related to the seismic performance assessment of underground structures are welcome.
