A non-local transient-gradient enhanced damage modelling method incorporating variable Poisson’s ratio for brittle bi-material composites Open
Widely reported damage modelling methods inherently use elastic brittle rapidly decaying responses for materials under both uniaxial tension and compression, in spite of the existence of ample experimental evidences that the damaging proce…

Numerical modelling of concrete bearing strength for different heights of concrete blocks Open
Bearing strength of concrete is one of important design characteristics in transmit the bearing force in structural supports such as column corbel, bridge bearing system, concrete connection, anchorage in post-tension members and other typ…

Effect of concrete block height variation to the shear bond strength of thin layer mortared masonry Open
Thin layered masonry employs thin mortar joints laid with minimally skilled masons. However, the applicability of this masonry system relies on units made with tighter control of their height. The standard unit height variation is tolerate…

A generalised damage model for masonry under compression Open
A generalised model based on damage mechanics for predicting the response of masonry subjected to compression is presented. The model accounts for the behaviour of the constituents of the masonry, viz., the units, the mortar and the unit–m…

Behaviour of thin layer mortared concrete masonry under combined shear and compression Open
This paper presents experimental studies on the behaviour of a thin layer polymer mortared concrete masonry under combined shear–compression. Thirty thin layer mortared concrete masonry panels with five bed joint orientations were construc…

Steel-concrete-steel composite columns subjected to lateral impact Open
Concrete-filled double skin tube (CFDST) is a creative innovation of steel-concrete-steel composite construction, formed by two concentric steel tubes separated by a concrete filler. Over the recent years, this column form has been widely …
View article: Out-of-plane deformation and failure of masonry walls with various forms of reinforcement
Out-of-plane deformation and failure of masonry walls with various forms of reinforcement Open
Out-of-plane behaviour of mortared and mortarless masonry walls with various forms of reinforcement, including unreinforced masonry as a base case is examined using a layered shell element based explicit finite element modelling method. Wa…

Effects of Principal Stress Axis Rotation on Unsaturated Rail Track Foundation Deterioration Open
Precise assessment of cyclic plastic deformation of rail track subgrade is essential in designing cost effective rail tracks. Plastic deformation of rail tracks is often underestimated due to the omission of effects of principal stress axi…

Cyclic plastic deformation characteristics of subgrade under moving train wheel load Open
Cyclic plastic deformation of subgrade and other engineered layers is generally not taken into account in the design of railway bridge transition zones, although the plastic deformation is the governing factor of frequent track deteriorati…
