This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A ...

The electron beam from the Stanford two-mile linear accelerator is analyzed by a high quality magnetic deflection system in the beam switchyard and transported to the experimental areas. The first magnetic element in this system is a group of pulsed magnets which are used to deflect the accelerator electron beam to either transport system on a pulse-to-pulse basis and with different energy puls...

R f search has produced two major procedures for assessing creep and shrinkage; the ACI 209 method' and the CE$-FJP method.' Laboratory research into concrete creep and shrinkage has been conducted for decades, and excellent analytical procedures for evaluating structures for creep and shrinkage have been presented in the literature.'-5 Creep and shrinkage are factors in the design of a variety...

We review the structure and evolution of a number of Riphean-Phanerozoic rifts and extensional basins within the territory of the former Soviet Union (FSU). Horst-and-graben formation in strong crustal and subcrustal lithosphere layers can explain the multi-trough character of rift systems observed in the Russian platform, the Vilyuy rift, the West Siberian rift system, the Pechora-Kolva rift s...

this paper describes a modified structural dynamics model for aeroelastic analysis of high-aspect-ratio wings undergoing large deformation behavior. to gain this aim, a moderate deflection beam model is modified with some important large deflection terms and then coupled with a state space unsteady aerodynamics model. finite element method is used to discretize the equations of motion. a dynami...

In electrocardiograms of normal human hearts recorded by precordial leads the initial ventricular complex shows a fairly constant configuration. With the right arm electrode placed at the apical region and the second electrode at any point distant from the heart the primary ventricular deflection consists of a conspicuous downward deflection followed by an upward deflection. The initial downwar...

The distributions of stresses and deflection in rectangular isotropic and orthotropic plates with central circular hole under transverse static loading have been studied using finite element method. The aim of author is to analyze the effect of D/A ratio (where D is hole diameter and A is plate width) upon stress concentration factor (SCF) and deflection in isotropic and orthotropic plates unde...

Nonlinear bending of shear deformable nanobeams subject to a temperature field is investigated in this paper based on von Kármán type nonlinearity and nonlocal elasticity theory. By using the variational principle approach, new higher-order governing differential equations and the corresponding higher-order boundary conditions both in the transverse and axial directions are derived and discusse...
