a reinforced concrete member in which the total span or shear span is especially small in relation to its depth is called a deep beam. in this study, a new approach based on the adaptive neural fuzzy inference system (anfis) is used to predict the shear strength of reinforced concrete (rc) deep beams. a constitutive relationship was obtained correlating the ultimate load with seven mechanical a...
Background Fiber reinforced composite (FRC) is a promising class of material that gives clinicians alternative treatment options. There are many FRC products available in the market based on either glass or polyethylene fiber type. The aim of this study was to present a comparison between glass and polyethylene fiber reinforced composites based on available literature review. Material and Met...
امروزه خطر انفجار بر روی سازه ها به عنوان یک حادثه تصادفی یا عمل خرابکارانه رو به افزایش است. یکی از روش های ایمن سازی سازه ها در برابر بار انفجار استفاده از سازه های محافظ می باشد. دیوارهای محافظ بتن مسلح یکی از سازه های کارامد و متداول در مقابله با بارهای انفجاری می باشند. به دلیل هزینه بر و طاقت فرسا بودن تحقیقات آزمایشگاهی پدیده انفجار، مدل سازی های نرم افزاری و عددی یکی از روش های مطلوب و ...
there is a worldwide interest in using fibers of different types in concrete mixtures. in this regard, as the use of pet fibers has gradually increased during the last decade, this study aims to investigate the effects of pet fibers on the mechanical properties of hardened concrete and the workability of fresh concrete. to this end, different contents of pet fibers (pc= %0, %0.5, %1 and %1.5) a...
: in the present paper, lessons are learnt from ant society so that humankind can optimize his engineering issues. as an example of such issues, a reinforced concrete retaining wall for which the application of optimization can reduce the costs involved is considered. traditional design procedure for reinforced concrete retaining walls is unable to design an optimized wall unless a large trial ...
