The Influence of Crack-Face Normal and Shear Stress Loading on Hydraulic Fracture-Tip Singular Plastic Fields
(2018)
We investigated the singular plastic fields at the crack tip of a fracture that is loaded with normal and shear loads due to a viscous flow in a hydraulic fracturing. The level of the expected shear load in comparison with ...
Seismic Rehabilitation of Substandard R.C. Buildings with Masonry Infills
(2018)
Seismic deformation demands are localized in areas of stiffness discontinuity, such as in the soft storys of frame structures, where disproportionate damage is often reported in post-earthquake reconnaissance. In many parts ...
Singular crack-tip plastic fields in Tresca and Mohr–Coulomb solids
(2018)
This paper investigates the singular plastic fields at crack tips for Tresca and Mohr–Coulomb materials with power law hardening response. The singular values and the corresponding fields were determined over a range of ...
Simplified method for rapid seismic assessment of older R.C. buildings
(2018)
After several years of progress in earthquake design procedures, existing reinforced concrete buildings that fall short of modern standards still represent the vast majority of the built environment. Poorly reinforced ...
Effect of yield penetration on column plastic hinge length
(2018)
The required confined zone in critical regions of columns and piers undergoing lateral sway during earthquakes is related to the plastic hinge length where inelastic deformation and damage develops. The exact definition ...
Collapse Fragility Curves for RC Buildings Exhibiting Brittle Failure Modes
(2018)
Defining the collapse probability of existing nonseismically designed RC buildings is a challenge mainly due to the fact that its determination relies on the simulation of the brittle failure modes controlling the collapse ...
