The TabaseColshan catastrophic earthquake of 16 September 1978 of magnitude M ~ 7 . 7 , the largest shock which has ever been recorded in Iran, occurred in Khorassan Province east central Iran (Fig. 1). The main shock took place in the evening, when most people were in their houses, at 19.38.18 local time (1535.58 GMT), without any felt foreshock. The preliminary instrumental epicentre is recor...

Background: Different bracing systems of steel Eccentric Braces (EBs) and steel-concrete Buckling-Restrained (BRBs) can be used in frames order to make the stronger resisting lateral loads. These with EBs or BRBs are generally called Eccentrically Braced Frames (EBFs) (BRBFs), respectively. Objective: This study aims investigate having moment link. Methods: The EBFs BRBFs nonlinearly analysed e...

In this paper, torsional behavior of asymmetric structures with fixed base and isolated base has been compared. Studied Structures are three-dimensional, three and eight story steel structures whose nonlinear time history analysis was conducted based on the records of El Centro earthquake (1940), Tabas earthquake (1978), and Bam earthquake (2003). Analysis results show the efficiency of seismic...

Dynamic behavior of ground supported cylindrical storage tanks (CST) is of crucial importance because of its applications in industrial complexes. Seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. Five CSTs with different height to diameter ratios, three CSTs with the same height and diameters but various fluid heights and one CST with t...

In this experiment, the chemical composition of the essential oils obtained from Ferula assa-foetida oleo-gum resin collected from two different sites of Yazd province (Tabas and Yazd) in the center of Iran, were identified. The gas chromatography mass-spectroscopy (GC/MS) data showed that the qualitative composition of the components appeared to be constant in two different regions. Moreover, ...

OBJECTIVE To find out the prevalence and relationship of anemia in reproductive age women in rural area of Tabas, center of Iran. Iron deficiency anemia is the most common nutritional problem, affecting about 41.8% of pregnant and 30.2% of non-pregnant women worldwide. MATERIALS AND METHODS A cross-sectional study was conducted on the random sample of 382 reproductive age women in rural areas...

Telecommunication tower is an important component of the basic infrastructure of communication systems and thus preserving them in events of natural disasters - such as a severe earthquake - is of high priority. In past studies, researchers have mostly considered the effects of wind and earthquake-induced loads on 3-legged (triangular cross-section) self-supporting steel telecommunication tower...
