A Study on Seismic Isolation of Shield Tunnel Using Quasi-Static Finite Element Method
Using a quasi-static method based on an axisymmetric finite element model for seismic response analysis of seismically isolated tunnels, the seismic isolation effect of the isolation layer is studied, and the seismic isolation mechanism of the isolation ...

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Evaluation of the seismic performance of isolated electrical transformers under pulse-like excitations [PDF]
Damage sustained by electrical transformers in past strong earthquakes led to irrecoverable and severe economic losses. The seismic performance evaluation is associated with the loss of proper functioning of transformers.

IMPROVE THE EFFICIENCY OF SEISMIC WITH RUBBER MOUNTS ELEMENTS COMBINED WITH DRY FRICTION
The goal is to increase effectiveness of seismic isolation of buildings with flexible rubber-seismic isolation bearings (RSIB). In order to reduce the maximum displacement RSIB installed in the basement of frame buildings in seismic isolation system ...

AbstractThis paper proposes a vertical distribution of seismic design load of seismically isolated buildings corresponding to diversity of seismic isolation devices such as hysteretic dampers and/or velocity‐dependent dampers. This proposed method is obtained from the relationship between response amplification caused by higher‐mode responses and key ...

SEISMIC PERFORMANCE OF BRIDGES ISOLATED WITH FPS [PDF]
The scope of the present study is focused on the evaluation of the seismic response of bridges isolated by single concave sliding pendulum isolators (FPS) for the different structural properties when the presence of the rigid abutment is considered or neglected (i.e., isolated viaducts).

SEISMIC MONITORING OF BUILDING WITH BASE ISOLATION
The seismic monitoring of buildings is important for two fundamental reasons: - evaluate the possible dynamic behavior of these structures during earthquakes; - gain experience on the general seismic behavior of the structures so that the experience and the database can be used in the future for design and analysis.
