In the history of earthquake thermal infrared research, it is undeniable that before and after strong earthquakes there are significant thermal infrared anomalies which have been interpreted as preseismic precursor in earthquake prediction and forecasting. In this paper, we studied the characteristics of thermal radiation observed before and after the 8 great earthquakes with magnitude up to Ms...

The influence of the near-fault ground motion on the response of long-span bridges must be considered as a critical factor for seismic design because the response indicates different aspects from existing earthquake characteristics. Also, it is important to note that the safety index for the risk assessment of long-span bridges is determined based on the minimum expected lifecycle cost E(LCC). ...

The method for parallel mechanism type synthesis is introduced based on the kinematic characteristics flow process from the joints to the end-effector of parallel mechanism. Some new kinds of redundant input parallel mechanisms are brought forward by this method. By adopting double-inputs interface module, a kind of parallel earthquake simulator is presented and manufactured. The according cont...

The earthquake engineering community recognizes the need to improve current seismic codes and design methods in the light of recent inadequate behavior of building structures. Presently, the performance-based earthquake engineering is being envisioned as the solution to this problem. In this new design approach, the desired behavior of the building is formulated first in the conceptual stage fo...

BACKGROUND Earthquakes cause thousands of deaths worldwide every year, and systematic study of the causes of these deaths can lead to their prevention. Few studies have examined how multiple types of risk factors are related to physical injury during an earthquake. METHODS A population based case-control study was conducted to examine how individual characteristics, building characteristics, ...

an earthquake with magnitude ms = 6.5 on the richter scale occurred in december 26th, 2003 in bam region in southeastern part of iran. this study investigates the chemical variations of the groundwater resources in the effected region. for this purpose, 30 wells were selected and chemical compounds, in terms of cations (ca+2, mg+2, na+, k+); anions (hco3, so4, cl, no2), as well as ec, tds and p...

background: global findings indicate that incidence rate of cutaneous leishmaniasis (cl) has significantly in­creased during the past decade, as documented in many countries. this review was aimed to evaluate the trend of cl cases in terms of demographic and clinical characteristics during a decade after the earthquake (2003–2012) com­pared to the corresponding period before the earthquake in b...

BACKGROUND Earthquakes and other catastrophic events frequently occurring worldwide can be considered as outliers and cause a growing and urgent need to improve our understanding of the negative effects imposed by such disasters. Earthquakes can intensively impact the birth outcomes upon psychological and morphological development of the unborn children, albeit detailed characteristics remain o...
