In this paper, we study gravitational collapse in the 5-dimensional Einstein-Gauss-Bonnet (EGB) theory. We construct spherical marginally trapped surfaces and determine their evolution when collapsing matter admits a wide class of initial density distributions. show that location, time formation depend crucially on density, velocity profile matter, as well Gauss-Bonnet (GB) coupling constant. p...

In this study, the progressive collapse potential of seismically designed steel plate shear wall (SPSW) systems is investigated using the alternate path method, and their performances are compared with those of the conventional special moment frame (SMF) systems. Nonlinear static and dynamic analyses are conducted to follow the progressive collapse of the structures, and their ability of absorb...

A companion paper by Andreassen et M. (this issue) introduced and used a nonlinear, compressible, spectral collocation code to address the relative evolutions of two-dimensionM motions obtained in twoand three-dimensionM simulations of gravity wave breaking. That study illustrated the effects of instability on the wave field and mean flow evolution and suggested that two-dimensionM models are u...

After the failure of an element in a structure, its loads should be redistributed on the other elements and the structure must provide some new paths to carry the load. If such new load paths are not provided, collapse progression will begin in the structure. As the beginning of progressive collapse in a structure is more sensitive to the missing of an element, the location of that element is m...

Nowadays, as a result of increased terrorist and bomb attacks throughout the globe in the vicinity of strategic buildings, designing these structures against impact loads, particularly the blast-related ones, has been taken into more consideration. The current procedure for designing the structure against an explosion is a design against the local failure of the current elements in the first st...

The formation of singularities in certain situations, such as the collapse of massive stars, is one of the unresolved issues in classical general relativity. Although no complete theory of quantum gravity exists, it is often suggested that quantum gravity effects may prevent the formation of these singularities. In this article we will present arguments that a quantized theory of gravity might ...
