Modeling Steel Plate Shear Wall (SPSW) behavior can be computationally demanding. This is especially true when high-fidelity modeling carried out via shell or 3D solid elements. It has been shown that SPSW captured with adequate accuracy through the strip method nonlinear truss elements idealization. The widely accepted and reliable analysis platform, OpenSees, requires text-based input (.tcl) ...

In this study, constant-ductility optimization algorithm under a family of earthquake ground motions is utilized to achieve uniform damage distribution over the height of steel moment resisting frames (SMRFs). SMRF structures with stiffness-degrading hysteric behavior are modeled as single-bay generic frame in which the plastic hinge is confined only at the beam ends and the bottom of the first...

The corrugated steel plate shear wall (CoSPSW) is a new type of wall, in which plates instead flat are adopted. lateral stiffness and buckling capacity the system could be significantly enhanced, then, under gravity loads would mitigated. This paper presents study on probabilistic assessment seismic performance vulnerability CoSPSWs using fragility functions. damage states corresponding repair ...

Erdos, F eller, and Pollard [2] pro ved that if the greatest common divi or of the k's with c,,>O is 1, then , Other theorems of the same type as theorem 1 were proved by T . Kaluza [4] . Assuming (1) , he showed for instance, that j (2) > 0, j (n l )j (n + 1) > p(n ) (n = 2,3, . .. ) imply that the c's are positive. Furthermore, he proved that j (I ),j(2), ... is a moment equence if, and only ...

Let T * C* x C* act meromorphically on a compact Kahler manifold X, e.g. algebraically on a projective manifold. The following is a basic question from geometric invariant theory whose answer is unknown even if .Vis projective. PROBLEM. Classify all T-invariant open subsets U of X such that the geometricquotient U —> U/Texists with U/Ta compact complex space (necessarily algebraic if Xis). In t...

Recent research using statistical moments to describe moving shapes through an image sequence has led to an interest in reconstructing moving shapes from their moment description. This paper discusses how the moment description through a series of frames might be used to predict missing or intermediate frames within a sequence. Additionally, this highlights generic aspects of moment reconstruct...

We present the angular distribution of the rare B decay, B → K∗(→ Kπ)l+l−. By studying the azimuthal angle distribution in the low invariant mass region of dileptons, we can probe new physics effects efficiently. In particular, this distribution is found to be quite sensitive to the ratio of the contributions from two independent magnetic moment operators, which also contribute to B → K∗γ. Ther...
