A hybrid concrete wall is made up of a traditional reinforced with post-tensioned technology. Recent research has shown that (PT) shear walls have wide range advantages when it comes to resisting lateral forces and moments caused by earthquake loading. To explore the PT behavior subjected seismic load, models were augmented various material models, including KCC, CDP, Winfrith for 2D under push...

In this study, non-linear behavior of diagonally stiffened steel plate shear walls as a seismic resisting system has been investigated, and theoretical formulas for estimating shear strength capacity of the system have been proposed. Several validated analytical finite element models of steel shear walls with various stiffener dimensions are generated to verify and compare the analytical and th...

Abstract Structural engineers should appropriately design concrete structures to resist lateral loads. Determining the adequate system for resisting expected loads is important control building drift. Choosing appropriate usually conducted assuming predicted forces are applied completed buildings at one step which commonly known as ordinary analysis ( OA ). Nevertheless, these constructed seque...

The bilateral organization of the vertebrate nervous system is underlain, ontogenically as well as topologically, by the notochord. Derived from mid-dorsal mesoderm, the notochord is a compression-resisting rod that plays a supporting role as the axial skeleton in larval or embryonic vertebrates and later as a template for the basicranium and vertebrae. Earlier in development, the notochord pla...

Coupling beams are considered one of the most important structural elements due to their vital role in resisting lateral loads by improving overall building stiffness and reducing impact overturning. The resistance coupled shear walls (CSWs) earthquakes depends on coupling beam (CB) for enhancing ductility system energy absorption capacity. There two main types beams; diagonally reinforced conv...

The effectiveness of slicing in cutting soft solids (i.e., transverse motion along the blade) is natural to anyone with even slightest kitchen experience, but underlying mechanism remains intriguing. This study seeks unveil mystic role by looking into effect friction materials. With increase indentation depth, nonlinearity large deformation superficial layer diverts lateral stress from compress...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

Few-layer graphene (FLG) and graphene oxide (GO) were explored to enhance the oxygen-atom corrosion resistance of composites. FLG flakes of two different average lateral sizes (large: ∼1.3 μm(2) and small: ∼0.23 μm(2)) were prepared by a centrifugation-based size selection route. After exposure to oxygen atoms, although all fillers could enhance the oxygen-atom corrosion resistance of the compo...

Performance based seismic design (PBSD) is an alternative to code based approaches to design or evaluation of structures that fail to yield a more direct relationship between a seismic event and the corresponding structural performance of a building; this generally leads to over-conservatism. This paper presents a case study on the alternative procedures used in the performance based design of ...
