During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls.  A few rein...

Reinforced concrete beams are normally designed as under-reinforced to provide ductile behaviour at failure i.e. the tensile moment of resistance, Mt(0), is less than the moment of resistance of the compressive zone, Mc. Since it is well established that the steel in reinforced concrete beams is prone to corrosion, the residual flexural strength is normally the main concern of asset managers. H...

The purpose of this study was to determine the influence of radial motion of an arterial wall on the shear stress that flowing blood imposes on the wall (wall shear stress). Wall shear stress is known to influence endothelial cell function and may play a role in atherogenesis, but its magnitude and distribution in the circulation are not well understood. To simulate arterial wall motion, we use...

Establishing a restoring force model is fundamental yet critical task for the analysis of structural responses to earthquakes. Such has substantial impact on results. Composite-shear walls with concealed bracings in steel-tube frames (composite-shear walls) offer several advantages, including convenient construction processes, high-bearing capacity, and excellent ductility. In this study, mecha...

Code design of unreinforced masonry (URM) brick buildings is based on elastic analysis, which requires as input, among others, estimates of the in-plane drift capacity at the considered limit states. Current approaches assess the drift capacity of URM walls by means of empirical models with most codes relating the drift capacity to the failure mode and wall slenderness. Comparisons with experim...

Among the different lateral force resisting systems, shear walls are of appropriate stiffness and hence are extensively employed in the design of high-rise structures. The architectural concerns regarding the safety of these structures have further widened the application of coupled shear walls. The present study investigated the optimal dimensional design of coupled shear walls based on the im...

This study investigates the strain localizations associated with Lüders deformation in mild steel using digital image correlation (DIC), a non contact, nondestructive, full field measurement technique for strain mapping. The focus is on the two substantial areas of interest such as shear deformation accompanying strain localization during Lüders instability and the complex morphology of Lüders ...

Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...

This paper describes an experimental investigation into the use of steel bars bonded into glulam timber beams with epoxy resins in order to provide moment-resisting joints between glulam beams and steel supports. The objective of this research was to provide information about the bending and shear strength of such connections. Past research has investigated the use of steel rods epoxy bonded in...
