Such memories amongst engineers have promoted this attitude that the shear walls structures exhibit a brittle overall performance. So the conviction that shear walls are inherently brittle still prevails amongst engineers, and therefore, they usually prefer to choose moment-resisting RC frames without shear walls. For getting an insight into the nonlinear behavior of RC shear walls, we have reviewed the experiments conducted on the RC shear walls. Besides, through using the post-earthquake reports written after major earthquakes, we have checked and scrutinized the seismic performance of RC frames equipped with shear walls too. Investigations performed on the nonlinear behavior of the shear walls have demonstrated that slender shear walls, designed to fail in flexural mode, could safely dissipate excitations energy of the earthquakes. These studies also revealed that even squat shear walls can be designed in a way that their behavior would be similar to those of the slender walls. Considering these matters, designed shear walls according to the recent codes maintain sufficient shear strength and respectable energy dissipation capability.","PeriodicalId":154515,"journal":{"name":"arXiv: Pattern Formation and Solitons","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115492579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In equilibrium condensates only quantum vortices of unit topological charge are stable, due to the dynamical instabilities of multiply charged defects, unless supported by strong external rotation. Due to immense fundamental interest in the physics of these fundamental topological excitations, a great deal of work has been expended towards understanding ways to force their stability. Here we show that in photonic Bose-Einstein condensates of exciton-polariton quasiparticles pumped in an annular geometry, not only do the constant particle fluxes intrinsic to the system naturally stabilize multiply charged vortex states, but that such states can indeed form spontaneously during the condensate formation through a dynamical symmetry breaking mechanism. We elucidate the properties of these novel states, notably finding that they radiate acoustically, in a process analogous to the emission of gravitational waves from binary black holes. Finally, we show that the vorticity of these photonic fluids are fundamentally limited by a quantum Kelvin-Helmholtz instability, and therefore by the condensate radius and pumping intensity. This represents the first report of this instability - deeply fundamental in fluid dynamics - in a quantum photonic fluid.","PeriodicalId":154515,"journal":{"name":"arXiv: Pattern Formation and Solitons","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127847197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The frustration is provided by the presence of both ferromagnetic and anti-ferromagnetic interactions between adjacent magnetic moments defined on the lattice nodes. At the critical value of the frustration $f=f_{cr}=3/4$ such a systems displays the phase transition from the ordered ferromagnetic state to the disordered frustration regime characterized by the highly-degenerated ground state. In the frustrated regime, $f_{cr}< f leq 1$, unexpected scaling of spatially averaged magnetization $langle vec{M} rangle $ on the total number of nodes,$N$, i.e. $langle vec{M} rangle simeq N^{-1/4}$, has been obtained. Such scaling is provided by highly anisotropic magnetic patterns displaying the ferromagnetic ordering along the $y$-direction, and short-range correlations of magnetic moments along the $x$-direction. We conjecture that all these intriguing features are explained by the presence of the double-degenerated ground state in the basic cell, i.e. single triangle, of the kagome lattice accompanying a large amount of intrinsic constraints. We anticipate the implementation of the phase transition and anisotropic magnetic patterns in various systems, e.g. natural magnetic molecular clusters, artificially prepared Josephson junctions networks, trapped-ions and/or photonic crystals.","PeriodicalId":154515,"journal":{"name":"arXiv: Pattern Formation and Solitons","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131383853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
