The step back-set back building is supported by stepped foundation where the foundation elevation and roof elevation are different. The complexity of seismic input of ste [...]

The rational structure model, inputting load and seismic response of structures in mountainous terrain are different from those of common structure in structure analysis [...]

Foundations located at different elevations will result in vertical structural irregularities of mountain structures. Usually, the vertical structural irregularities can [...]

The selection of ground motion is a critical problem which can influence the structural response in seismic design and analysis. Nevertheless, the proposed intensity inde [...]

Recent studies have shown that axial tension may be experienced by beams of some structures, such as structures supported by foundations with different elevations. Thus t [...]

The Wenchuan earthquake of May 12th 2008 had a magnitude 8.0 on the Richter scale, focal depth of 14 km according to the Chinese Earthquake Administration (CEA). Maximum [...]

The basic aim of this study is to investigate the nonlinear performance of a ten story special moment resisting frame (SMRF). The elements are designed based on the 1997 [...]

Torsional response of structures would be changed while some lateral load resisting members yield. The present article pertains to nonlinear vibration characteristics and [...]

The M8.0 Wenchuan Earthquake was one of the most catastrophic earthquakes in modern history ,which happened in WencChuan county Sichuan province at 14:28 on May 12, 2008. [...]

Considerable attention has been paid to the nonstationarity in frequency contents of ground motions and many methods have been proposed to study this property. But most o [...]
