Fatigue Reliability Assessment for Orthotropic Steel Decks Based on Long-Term Strain Monitoring
A time-dependent fatigue reliability assessment approach is proposed for welded details of orthotropic steel decks (OSDs) using long-term strain monitoring data. The fatigue reliability limit function of the welded details is established based on the Eurocode specifications. Depending on the distribution characteristics of the measured daily equivalent stress range, either the lognormal distrib...

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولFatigue Reliability Assessment of Orthotropic Steel Bridge Decks Based on Probabilistic Multi-scale Finite Element Analysis
The orthotropic steel deck (OSD) has been utilized successfully for thousands of bridges worldwide; however, fatigue cracking of the OSD has been observed frequently due to the complicated welded details combined with stresses that can be difficult to quantify, and the uncertainties in fatigue damage accumulation. In this paper, a fatigue reliability assessment method is proposed based on a com...
متن کاملThe Effect of Analysis Methods on the Response of Steel Dual-System Frame Buildings for Seismic Retrofitting
In the present paper, the focus is on the evaluation of steel dual-system frame buildings using four main types of structural analysis (Linear Static, Linear Dynamic, Nonlinear Static and Nonlinear Dynamic Analyses) with regard to "Seismic Rehabilitation Code for Existing Buildings in Iran" (based on FEMA 273 and 356) where the first two authors of the article tend to follow the previous work (...
متن کاملProposing the simplified model for choosing the method of retrofitting in existing structures against fire risk
Background and objective: According to the necessities in the part 3 of National Building Regulations, design and construction of buildings should be in a way that the structures, according to the type of use, the size and the number of floors, resist long enough to fire, and prevent from destruction of buildings or from spread of fire to adjacent spaces or buildings. For this purpose, it is ne...
