A stress-path dependent stress-strain model for FRP-confined concrete
TL;DR: In this article, a stress-strain model was developed to better understand and simulate the behaviour of FRP-confined concrete, which consists of the following three main components: (1) a hoop strain equation elaborated from the authors' previous study on steel-constrained concrete columns for application to FRP confined concrete; (2) a modified confined concrete model considering stresspath of confining stress (or history of hoop strain); (3) Interaction between FRP and concrete.
Journal ArticleDOI
Confinement effect of ring-confined concrete-filled-steel-tube columns under uni-axial load
M.H. Lai,Johnny Ching Ming Ho +1 more
TL;DR: In this paper, the axial load-carrying capacity of unconfined and ring-confined concrete-filled steel-tube (CFST) columns was investigated under uni-axial compression.
Journal ArticleDOI
A path dependent stress-strain model for concrete-filled-steel-tube column
TL;DR: In this paper, a theoretical stress-strain model for concrete-filled steel-tube (CFST) columns was developed to better understand and simulate the behavior of CFST column, which consists of the following four main components: (1) Interaction between steel tube and concrete taken into account the de-bonding effect; (2) an accurate hoop strain equation; (3) a passively confined concrete model considering stress-path dependence; (4) a three-dimensional stress-strain model for steel tube.
Journal ArticleDOI
A theoretical axial stress-strain model for circular concrete-filled-steel-tube columns
M.H. Lai,Johnny Ching Ming Ho +1 more
TL;DR: In this paper, an experimental database containing 422 uni-axial compression test results of unconfined and externally confined concrete-filled-steel-tube (CFST) columns has been assembled.
Journal ArticleDOI
Fillers to improve passing ability of concrete
TL;DR: In this article, fly ash and silica fume (cementitious fillers) and limestone (inert filler) were selected to replace cement partially and subsequently the passing ability of concrete was studied.
