The results of the studies are presented which is an extension earlier authors’ work combined bolted-welded joints for building steel structures. Data on parameters stress-strain state finite-element models physical specimens bolted, welded and connections given. These manufactured being prepared testing. There some special features design numerical models: conditions have been created realizat...

Fretting fatigue is a damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing reduced life respect the plain case. has now been studied deeply for over 50 years, but still no univocal design approach universally accepted. This review presents literature study involves three main types of mechanical joint affected by fretting (press-f...

Bolted spherical joints are widely used in space grid structures. However, the preload loss, which may arise from fabrication error, insufficient twist of screw and some other unknown reasons can undermine structural integrity even lead to collapse whole structure. Therefore, a method for evaluating status bolted is vital health monitoring To this end, non-destructive evaluation loss based on t...

This paper reviews Fibre Reinforced Polymer (FRP) composites in Civil Engineering applications. Three FRP types are used Structural Engineering: profiles for new construction, rebars and strengthening systems. Basic materials (fibres resins), manufacturing processes material properties discussed. The focus of the is on all-FRP new-build structures their joints. All-FRP use pultruded profiles. T...
