In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction (C-PFI) method”, has been introduced to predict the shear behavior of the composite steel plate shear wall systems (CSPSWs). In the second part, several models of one-story ...

Predicting the values that are likely to be produced by instructions has been suggested as a way of increasing the instruction-level parallelism available in a wide-issue processor. One of the potential difficulties in exploiting the predictability of values, however, is selecting the proper type of predictor, such as a last-value predictor, a stride predictor, or a context-based predictor, for...

We discuss the problem of static chaos in spin glasses. In the case of magnetic field perturbations, we propose a scaling theory for the spin-glass phase. Using the mean-field approach we argue that some pure states are suppressed by the magnetic field and their free energy cost is determined by the finite-temperature fixed point exponents. In this framework, numerical results suggest that mean...

The static singlet potential between a heavy quark and an antiquark is an object of considerable interest both theoretically and phenomenologically. Strictly speaking, the potential being a dynamical quantity, it can be defined only in a context where the full dynamics of the system is consistently taken into account, for instance, in the proper Schrödinger equation. Nevertheless, the static si...

Pitting corrosion is one of the most common forms of localized corrosion. Corrosion pit results in a stress concentration and fatigue cracks usually initiate and propagate from these corrosion pits. Aging structures may fracture when the fatigue crack reaches a critical size. This paper experimentally simulates the effects of pitting morphologies on the static and fatigue behavior of steel bars...

BACKGROUND Static trunk flexion working postures and disturbed trunk muscle reflexes are related to increased risk of low-back pain. Animal studies conclude that these factors may be related; passive tissue strain in spinal ligaments causes subsequent short-term changes in reflex. Although studies have documented changes in the myoelectric onset angle of flexion-relaxation following prolonged s...

We de ne a new notion of function pattern, which supports runtime pattern matching on functions based on their behavior. The ability to runtime dispatch on function type information enables new programmer expressiveness, including support of overloading on higherorder functions as well as other useful patterns. We formally present a type inference system for function patterns. The system answer...

We use an analytic perturbation expansion for the two-band system of tight binding electrons to discuss Bloch oscillations and Zener tunneling within this model. We make comparison with recent numerical results and predict analytically the frequency of radiation expected from Zener tunneling, including its disappearance, as a function of the system parameters. PACS numbers: 71.70.Ej, 73.40.Gk, ...

This paper presents a new notation for the formal representation of the static structure and dynamic behavior of software, based on description logics and temporal logics. The static structure as described by UML class diagrams is represented formally by description logics while the dynamic behavior is represented by linear temporal logic and state transition systems. We integrate these descrip...

Auxetic materials expand when stretched, and shrink when compressed. This is the result of a negative Poisson’s ratio n. Isotropic configurations with n 1 have been designed and are expected to provide increased shear stiffness G. This assumes that Young’s modulus and n can be engineered independently. In this article, a micropolarcontinuum model is employed to describe the behavior of a repres...
