Over the past few years, accompanied by big and frequent earthquakes, more attention was
paid to the tunnel earthquake resistance. To reduce tunnel seismic damage and explore the …

Seismic performance of rectangular underground structures as a hot topic was studied
systematically for decades. However, less attention was paid to the functionalities of the …

Fragility analysis constitutes the basis in seismic risk assessment and performance-based
earthquake engineering during which the probability of a structure response exceeding a …

Isolation bearings have been a widely applied seismic strengthening technique in above
ground structures. Whereas, the sliding isolation bearings were seldom used in …

Existing studies on earthquake damage have shown that the center column of a shallow-
covered underground structure is more prone to be damaged by a strong earthquake than …

The seismic design concept of base isolation is widely used in the aboveground structures,
and the typical isolation device is friction pendulum bearing (FPB). However, there are …

In order to improve the seismic performance of underground subway station structures while
taking advantage of modular assembly technology, a novel partially prefabricated structure …

A series of shaking-table tests of a subway station structure with mini natural rubber
bearings (Mini-NRBs) installed at column ends were carried out for near-field earthquake …

The seismic response of the underground structure is mainly affected by the restraint of the
surrounding soil rather than the inertial effect, which is quite different from the ground …

Underground structures are vulnerable to strong earthquakes, with their central columns
being prone to damage owing to their insufficient resistance capacity. In this study, an …
