The experiences for leakage examination are presented and several break holes are then identified thanks to the permeability of concrete and the localization property for gas leakage from inside to outside of the containment vessel.
In order to describe strain localization in concrete, a non-local constitutive model was applied with account for a characteristic length of micro-structure developing in the softening regime.
The article discusses the damage localization of concrete columns by means of vibration analysis techniques.
The use of socket-type connections is beneficial for spreading inelasticity at the base of composite columns, without damaging the localization on concrete and interface components.
Furthermore, socket-type connections are characterized by spreading of inelasticity at the base of the composite columns without damage localization on concrete and interface components.
To ensure the mesh-independence and to capture strain localization in concrete, both criteria were extended by a characteristic length of microstructure in a softening regime with the aid of a non-local theory.
After that, the lengths of plastic hinge zones, including rebar yielding zone, curvature localization zone, concrete crushing zone, and equivalent plastic hinge, of RC columns subjected to monotonic and cyclic loading are studied in detail under different parameters.
The digital image correlation technique was applied to visualize strain localization on the concrete surface.
Lengths in the plastic hinge region involving rebar yielding zone, concrete crushing zone and curvature localization zone are studied systematically, under different parameters.
This paper presents an experimental verification and quantification of the cracking localization phenomenon in reinforced concrete (RC) tensile prismatic bars with steel fibers.
