assessment of the park- ang damage index for performance levels of rc moment resisting frames

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 ...

Rotation Crop Evaluation for Management of the Soybean Cyst Nematode in Minnesota

Crop rotation is an effective tactic for soybean cyst nematode (SCN) management. In the North Central region of the USA, corn is almost exclusively used as a nonhost rotation crop with soybean. This study was conducted to determine the effectiveness of crops common to or having potential use in the North Central region as rotation crops for managing SCN. Sixteen potential rotation crops and SCN...

Ergonomic evaluation of conventional agricultural sprayers with respect to human performance

Ergonomic intervention in spraying operation can provide a reasonable basis for recommendation on operating methods and improvement in operation for more output and safety. Two commercially available sprayers namely knapsack sprayer and rocker sprayer were evaluated with nine male subjects for the study. Age, weight and height of the selected subjects are 30.33±1.93 years, 68.33±9.51 kg and 168...
