Seismic Design Considerations for Underground Box Structures
بارگذاری لرزه ای ایستگاه های زیرزمینی مترو - مقطع مستطیلی
یوسف هشاش
استاد دانشگاه ایلینوی
ABSTRACT
Underground structures have generally performed well during seismic events.
Nevertheless the design of these structures has to consider seismic loading. Unlike
above ground structures,the response of undergound structures to seismic loading is
dominated by the seismic deformations of the surrounding soil. Seismic loading is
characterized in terms of deformations imposed by the soil on the box structures and
the interaction between them. This paper describes seismic analysis approaches for
underground structures. The paper reviews available simplified solutions and
describes procedures to conduct numerical analyses using pseudo-static and dynamic
soil-structure interaction approaches. The paper describes some of the limitations
associated with pseudo-static analyses for shallow structure and the need for dynamic
soil-structure analyses under these conditions.
