This paper presents an experimental investigation of the effect load path on force-displacement response, damage patterns, and failure modes slender lightly reinforced concrete (RC) columns. A review available tests, which include columns subjected to multiaxial loading protocols, is first presented. Next, a new campaign 18 column specimens tested under constant axial lateral displacement-contr...

The fast flavor instability (FFI) is expected to be ubiquitous in core-collapse supernovae and neutron star mergers. It rapidly shuffles neutrino a way that could impact the explosion mechanism, signals, mass outflows, nucleosynthesis. variety of initial conditions simulation methods employed simulations FFI prevent an apples-to-apples comparison results. We simulate standardized test problem u...

This paper compares two physical mechanisms for the collapse of a bubble near a rigid wall: a traveling shock-induced collapse and a Rayleigh-like collapse due to a uniform rise of the pressure around the bubble. A multi-material compressible flow solver capable of handling material interfaces under high pressures is used to investigate these two scenarios for different levels of the driving pr...

The existence of torsion, as well as consideration of the Soil-Structure Interaction (SSI), increase the natural periods of the structure resulting from a subsequent decrease in the seismic demand of the system. This paper summarizes the probabilistic assessment for evaluation of collapse fragility curves in concrete moment resisting structure with different mass center eccentricities. A 12-sto...

In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...

Expansive and collapsible soils are some of the most widely distributed and costly of geologic hazards. These soils are subject to changes in volume and settlement in response to wetting and drying, often resulting in severe damage to structures. Collapsing soils are generally characterized by sudden and large volume decrease at constant stress when inundated with water. A geotechnical engineer...
