چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
The determination of structural and nonstructural damage under earthquake excitations is usually considered as a key factor in performance-based seismic design (PBSD) methods is In this regard, various damage indices have been developed in recent years to quantitatively estimate structural damage. The aim of this study is to develop a simple method to evaluate performance levels of zipper-brace...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
objective (s):rheumatoid arthritis (ra) is a chronic systemic inflammatory disorder, primarily targeting the synovium and articular cartilage that leads to joint damage. recent reports have suggested the role of adipocytokines in mediating joint damage; however it still is a matter of debate. the purpose of this study was to evaluate the association between serum values of adiopocytokines (lept...

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
This paper presents a classification of cavitation damage levels on spillway surface. Two important factors influencing cavitation damage have been considered in this study, flow velocity and cavitation index. Based on these factors, five different damage levels from no cavitation damage to major cavitation damage have been determined. The method was applied to data of the Shahid Abbaspour dam ...
In 2013, the World Health Organization (WHO) recommended concentrationresponse functions (CRF) for three major pollutants: fine particles (PM2.5), ozone (O3) and nitrogen dioxide (NO2) in its Health Risks of Air Pollution in Europe (HRAPIE) report.3 Effects were classified into two groups: group A (pollutant-outcome pairs for which enough data are available to enable reliable quantification of ...
