Analytical Study Regarding the Seismic Response of a Moment-Resisting (MR) Reinforced Concrete (RC) Frame System with Reduced Cross Sections of the RC Beams

چکیده
In the last few decades, a series of earthquakes were recorded which pointed out several deficiencies regarding ductile seismic response MR RC frame structures. Thus, research problem centres around failure mechanisms registered by structures, differ from general notions commonly found in current design standards and norms actions. these conditions, present paper—by using comparative methods—the analytical validation solution plastic hinge concentration energy dissipation marginal beam areas is proposed. Therefore, sections reduced (weakened) exhibit deformation potential, as well corner concrete slabs with vertical rectangular holes. The significant outcomes this imply partial “guiding” hinges zones adjacent to ends. Furthermore, reduction both negative effects horizontal rigidization beams cracking beam-column joints was observed. With technical implications, complex mechanism models all lateral elements (including columns) participate energy, without occurrence “weak storey” for any models. it possible observe formation global “Strong Columns—Weak Beams” (SCWB) some structural Finally, analytically studied innovative element improvement pure structures successfully validated.

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 ...
15 صفحه اولSeismic fragility assessment of RC moment resisting frame buildings designed for different editions of Iranian seismic design code
Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...

Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...
