Explosions caused by standoff charges near buildings have drastic effects on the internal and external structural elements which can cause loss of life fatal injuries in case failure or collapse element. Providing with blast resistance is therefore gaining increasing importance. This paper presents numerical investigation RC columns different reinforcement detailing subjected to near-field expl...

This study develops three-dimensional (3D) finite element (FE) models of composite retrofits in deficient reinforced concrete (RC) columns and frames. The aim is to investigate critical cases RC with inadequate lap splices bars or corroded steel reinforcements the beneficial effects external FRP jacketing avoid their premature failure structural collapse. Similarly, RC-frame FE explore an innov...

Abstract Reinforced concrete (RC) elements suffer continuous deterioration across their lifetime from in situ aggressive environmental factors. Chloride‐induced of the steel reinforcement presents significant repercussions on mechanical and seismic behavior affected RC members. This paper introduces summarizes experimental work carried out at University Canterbury, investigating long‐term impli...

A restoring-force model is a versatile mathematical that can describe the relationship between restoring force and deformation obtained from large number of experiments. Over past few decades, body work on development models has been reported in literature. Under high intensity cyclic loadings or seismic excitations, reinforced concrete (RC) structures undergo wide range hysteretic deterioratio...
