Response history analyses are usually conducted to evaluate seismic performance of
buildings. Since azimuth-dependent buildings are quite common in practice, bidirectional …

The shear keys are set in a seismic isolation system to resist the long-term service loadings,
and are cut off to isolate the earthquakes. This paper investigated the influence of shear …

A complex yet realistic nonuniform rolling friction force distribution of a spring-rolling
isolation system could lead to great complexity in determining its seismic response. This …

This article attempted to improve the isolation performance of a rolling isolation system by
assuming that the rolling friction force gradually and linearly increased with the relative …

As for structures with rubber bearings during earthquakes, some firstly damaged bearings
and the other normal bearings form a typical spring-friction isolation system. Furthermore, a …

This paper proposes two algorithms to generate spectrum-compatible time histories based
on two approaches recommended by USNRC Standard Review Plan 3.7. 1. Hilbert–Huang …

Although friction-based isolation systems have been studied for many years, their seismic
performance and influence factors have not yet been fully analyzed. This paper used a …

In current seismic design codes, various elastic design acceleration spectra are defined
considering different seismological and soil characteristics and are widely used tool for …

'Stepped building'frames, with vertical geometric irregularity, are now increasingly
encountered in modern urban constructions. This paper proposes a new approach to …

Displacement‐based seismic design methods support the performance‐based seismic
design philosophy known to be the most advanced seismic design theory. This paper …
