The finite element model of a new staggered story isolated structure is established. Using the time-history analysis method, dynamic response state at each time step calculated by integrating acceleration data step-by-step. Three different types seismic waves (ordinary wave, near-fault impulse far-field quasi harmonic and long-period wave) are input respectively for history analysis. result ind...

on 11th of august 2012 the region was surprisingly struck by a shallow mw 6.4 (usgs) earthquake with pure right-lateral strike-slip character only about 50 km north of the north-tabriz fault. an east-west striking surface rupture of about 20 km length was observed in the field by geological survey of iran. only 11 minutes later and about 6 km further nw a second shallow event with mw 6.2 occurr...

[1] The space‐time fault displacement history of the 11 March 2011 Tohoku (Mw 9.1) megathrust earthquake is obtained by least‐squares inversion of high‐rate (1 sample per second) GPS ground motions recorded in Japan. Complete near‐source time‐varying and static ground motions for periods ≥25 s are fit in the inversion using a normal mode formalism to compute the Green functions. The basic ruptu...

In recent years, there has been a growing recognition that the rocking motion of structures, especially cylindrical ones, should be evaluated with three-dimensional (3D) models. However, dissipation mechanisms in 3D models are complex and have yet to well established. This paper presents an analytical study on inherent mechanism based rolling friction model external energy dissipators (EDs) for...

Ground motions recorded in near-fault regions may contain pulse-like traces the velocity domain. Their long periodicity can identify such signals with large amplitudes. Impulsive be hazardous for buildings, creating demands due to their periods. In this study, a dataset was collected from various data centres. Initially, all impulsive signals, which are reality rare, manually identified. Furthe...

Establishing suitable probabilistic seismic demand models (PSDMs) is a key part of the performance-based method. Intensity measures (IMs) are used as connection between earthquake hazard and response in engineering. This study identifies optimal intensity for steel Modular Building Systems (MBSs) subjected to near-field ground motions. It achieved by performing Cloud analysis utilizing two sets...
