Comparison study on seismic isolation design of RC frame structure based on two different codes [PDF]
With the development of building seismic isolation technology and the official release of the Isolation Code in September 2021, seismic isolation design in China will now rely on two foundational codes: the Seismic Code and the Isolation Code. This paper

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.

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).

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 ...
