concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...
A wide range of materials and scaffolding fabrication methods for bone tissue engineering have beenexplored recently. Fiber reinforced polymers (FRP) system appears to be a suitable system. By the exclusiveuse of biocompatible or bio-absorbable polymers and fibers, novel generation of scaffolds for applicationsin tissue engineering can be prepared. Mulberry Silk as highlighted...
ویروس برگ باد بزنی مو (Grapevine fanleaf virus, GFLV) در تاکستانهای مناطق مختلف دنیا شیوع دارد. علایم ایجاد شده توسط این ویروس اغلب در سه سندرم برگ بادبزنی، موزاییک زرد و رگ نواری تقسیم بندی شدهاند که علت تفاوت در ایجاد علایم به تنوع ژنتیکی جدایهها نسبت داده شدهاست. از اینرو در این تحقیق تنوع ژنتیکی GFLV 2AHP بویژه در جدایههای همراه با علایم زردی بررسی شد. نمونهها از تاکستانهای بناب، ...
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...
This paper highlights the philosophy and concepts used for of the design of prestressed concrete structures prestressed by fibre reinforced polymer (FRP) tendons and rods proposed for the Canadian Standards Association (CSA) S806-00 Standard "Design and Construction of Building Components with Fibre Reinforced Polymers". The paper deals with the section of the code which applies to concrete bea...
The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete columns. The column specimens are circular in shape ...
Restoring forces, which are generated when the left ventricle contracts below its equilibrium volume (Veq), are responsible for diastolic suction. Their magnitude is inversely related to end-systolic volume (ESV). In previous studies in which the mitral valve was replaced with a prosthesis, increased contractility was shown to augment restoring forces independently of ESV. In the present study,...
Graphical user interfaces (GUIs) mediate almost all of our interactions with computers, whether it is through web pages, phone apps, or desktop applications. Functional Reactive Programming (FRP) is a promising approach to GUI design. This thesis presents Elm, a concurrent FRP language focused on easily creating responsive GUIs. Elm has two major features: (1) purely functional graphical layout...
Fiber reinforced polymer (FRP) composites are being promoted as the materials of 21st century because of their superior corrosion resistance, excellent thermo-mechanical properties, and high strength-to-weight ratio. For over 25 years, the Constructed Facilities Center at West Virginia University (CFC-WVU) has been conducting research on fundamentals of engineering and material sciences, innova...
A global approximation method to optimize material architecture and cross-sectional area of new fiber reinforced plastic (FRP) composite beams is presented. The sections considered are intended for applications in short-span bridges. The beams are subjected to transverse loading, and the optimization constraints include deflection limit, material failure, and elastic buckling. Assuming a lamina...
